Are you planning a home renovation project? Building a new parking lot? Or do you need someone to handle the groundwork and foundation for your new residential or commercial building projects? Whatever your reason is, choosing a good concrete contractor in San Jose can be a daunting task especially when you’re completely clueless on how to start. 

Don’t worry, we’ve got you covered! We know how important it is to find someone trustworthy to get the job done right. This guide will walk you through some simple tips and tricks for finding good concrete contractors. From checking out their experience to reading reviews, we’ll cover all the bases to make sure that your project is in good hands. 

Do your research

First off, you need to research concrete contractors in the San Jose area. It’s crucial to do your homework when looking for concrete contractors. You can start by checking out online directories like Google and even asking friends and family for recommendations.

After that, you can proceed to check out the testimonials indicated on their websites or social media accounts. When doing this, you have to pay attention to things like quality of work, communication, and overall satisfaction because they’ll give you a good idea of what to expect! Paving companies that are proud of their work show it off on their social media.

Evaluate their experience and expertise

When it comes to choosing concrete contractors, experience is key. You need someone who is experienced and knows all the ins and outs of what they’re doing.

So, how can you tell if a concrete contractor has the right experience? You can start by asking about the past projects they’ve worked on, how long they’ve been in the business, and if they specialize in doing concrete projects.

You want an excellent concrete contractor with experience in a variety of concrete services, whether it’s creating a new driveway or fixing cracks. 

Check their licensing

Making sure your concrete contractor is licensed is a big deal. So, if in any case something goes wrong, you want to make sure your project is well covered!

To check if a contractor is legit, you can usually ask for their license number and check with your local licensing board. 

Hiring licensed and insured concrete contractors isn’t just about playing by the rules but it’s also about keeping everyone safe. Plus, it guarantees that your project is compliant with the law, so you can have peace of mind knowing everything’s legal.

Request Detailed Quotes

Asking for a detailed quote for your concrete project is a wise move that everyone should do. This will help you budget every dollar you spend and make sure that there are no unexpected expenses along the way! 

What to look for in a quote? You can look for things like the cost of materials, labor, and any additional fees or taxes. The more details, the better! Once you’ve gathered quotes from different concrete contractors, you can compare and evaluate each quote while taking note of their similarities and differences. This will help you figure out which concrete contractor is the best match for your budget and needs.

Communication and Professionalism

Establishing good communication with concrete contractors will make sure that everyone’s on the same page. Miscommunications during the project are the last thing we want, which makes this part crucial.

When meeting with a contractor for the first time, you have to keep an eye out for signs of professionalism, like showing up on time, listening attentively to your needs, and being honest and transparent about their process. 

Whether it’s discussing project timelines or addressing any concerns, keeping the lines of communication open will result in a smooth journey to the success of your concrete project. 

Don’t forget to ask the right questions! 

Before you proceed with starting your concrete project, you need to ask questions to get to know them better! You can ask about things like their experience, previous projects, and how they handle challenges. 

Take note of how quickly the concrete contractors respond to your inquiries and how transparent they are about their process. This part is crucial especially when problems arise in the middle of the project.

Asking questions is a great way to establish understanding and trust as well as gain knowledge.  Here’s a list of sample questions you can ask your concrete contractor:

  1. Who are your material suppliers and why?

  2. What is your working day like?

  3. How will additional charges be dealt with?

  4. How do you handle unexpected issues or changes during the project?

  5. What is your policy on cleaning up the job site at the end of each day?

It’s time to finalize everything and make a choice

Start off by carefully reviewing all the information you’ve gathered from the tips above. Consider different factors like the contractor’s experience, cost, and how well you trust the contractor. Trust your instincts and go with what feels right for you!

Remember that when it comes to contract and timeline negotiations, finding common ground is important. So, don’t hesitate to ask questions to your concrete contractors and speak up whenever there’s something that doesn’t quite line up with what you had in mind. 

After all that, never forget to finalize everything by signing a detailed contract. This detailed contract lays out all the terms and expectations for your concrete project.

7 Tips for Maintaining Pavement in the Bay Area

cavlac paving in San Jose commercial asphalt road

Pavement is an integral piece of our day-to-day infrastructure and movement in the Bay Area – although it may not be something most of us think about on a daily basis. In fact, you know pavement has been well-laid and well-maintained when it is hardly noticed at all! Smooth surfaces, little-to-no cracks, and a sidewalk or parking lot void of vegetation allows you to get from your point A to point B in the Bay Area without a second thought. 

It is when pavement has not been maintained well, however, that it is noticed. A jolt from driving over a pothole in a parking lot, a trip over uneven pavement and its cracks, or an unexpected step in pooling water brings poorly cared for pavement to our attention, and they are clear indicators that pavement needs some attention. It is best for everyone to avoid scenarios such as these altogether! Let’s take a look at seven ways concrete companies and asphalt companies in the Bay Area maintain pavement and help you avoid the need for major rehabilitation over time.  

1 – Sealcoating

One of the surest ways to extend the life of your pavement is to apply a sealcoat. Typically, this should be done within thirty to ninety days after pavement installation. To be truly effective in ensuring pavement longevity, sealcoating should be done again every two to three years. Not only does sealcoating protect the surface of the pavement from UV rays, water penetration, and other environmental factors common to the Bay Area, but it can extend the life of your pavement up to 20 years! These protective factors, along with improving the appearance of your pavement, makes regular sealcoating a worthy investment of your time and resources. 

2 – Crack Sealing

Any cracks in your pavement should be promptly addressed to prevent water infiltration, which can cause damage as weather shifts from warm to cold and back. We normally crack-seal the same day we apply sealer. This is almost universally performed from spring through early fall. This allows the sealant to more easily penetrate the cracks in the pavement. 

Although crack sealing may be a more expensive maintenance action for you as the pavement owner, this is outweighed by the value of an extended pavement life expectancy. Crack sealing may last for up to five years or more, preventing the formation of potholes and extending the life of your pavement. 

3 – Pothole Repairs

If potholes do form in your pavement, they should be quickly addressed to prevent their expansion and the occurrence of more significant damage. Asphalt and pavement companies would recommend using the best materials and techniques to result in longer-lasting and more durable pothole repairs. 

4 – Proper Drainage

Proper drainage is crucial to ensuring the extended life of your pavement. The drainage of your pavement should be such that it prevents water from pooling. This means that correct grading and drainage systems are crucial upon installation. Should you notice drainage issues with your pavement, it is recommended to consult with a trusted asphalt and paving company on how to best implement repair and quickly avoid any water-related damages. 

5 – Vegetation Control & Routine Cleaning

A simple and cost-effective means for maintaining the life of your pavement is to consistently inspect and promptly remove any vegetation that may pop up through the cracks in your pavement. In a moisture-prone climate such as the Bay Area, the appearance of vegetation between cracks in pavement is inevitable. The simple and essential means of vegetation-maintenance will help you avoid potential damage which vegetation can cause in your pavement. In the same way, routine cleaning by sweeping away dirt, debris and leaves will help sustain both the integrity and look of your pavement over time. 

6 – Professional Inspections

In order to extend the life of your pavement, it would be to your advantage to hire a professional pavement company to take an in-depth look at the condition of your pavement every few years. The expert eyes of a trusted company will be able to take an assessment of the state of your pavement and provide you with professional recommendations for any repairs or maintenance required. 

7 – Responsive Repairs

One of the most important things you can do to protect and maintain your pavement is to immediately address any small issues or damage that may arise. By doing this on a regular basis, you will avoid small issues snowballing into larger, more expensive repairs down the road. 

At Calvac Paving, we complete each job with our high-quality materials and equipment to ensure the longevity of your paving in the Bay Area. When you work with us for your paving needs, you can trust that the end result will be reliable, long-lasting, and visually pleasing for years to come. Contact us today!

Maintenance Monday: 5 Areas to Consider as you Decide if Concrete or Asphalt is Right for You.

Maintenance Monday:

5 Areas to Consider as you Decide if Concrete or Asphalt is Right for You.

Calvac Paving Bay Area

As a property owner, you know more than anyone the importance of making an informed choice when it comes to your space. Whether you are making decisions ranging from structural integrity to landscape design, you know the value of using quality materials, and how these choices will provide longevity and create an inviting aesthetic for your property. 

At Calvac Paving, we know that one of the most important decisions you can make is how to pave your property’s parking lot. With this in mind, we want you to have the information you need to make the most informed choice for your next paving project. As a concrete and asphalt company that has served the Bay Area for 50 years, we believe that with the right information, property owners can make a paving decision that will serve them well for the years to come. 

As you begin planning to make the next big decision for your property, here is everything you need to know as you decide between concrete and asphalt.

1 – Composition and Production


Asphalt is created by mixing aggregates (sand, gravel, or crushed stone) with binder and filler. When this mixture is heated, it becomes pliable and can be smoothed into a flat surface. 


Concrete is composed of cement, aggregates, and water. Through a mixing process, concrete becomes a stone-like, hard material. 

2 – Appearance


Asphalt is dark in appearance, typically black or dark brown. There is little room for color customization with asphalt, as the materials used to create asphalt result in a dark and sleek tone with a single texture. 


Unlike asphalt, concrete can vary in both color and texture. Colors can range from dark to light, and texture from smooth to coarse. Choices with concrete can be made to meet a variety of aesthetic preferences. 

Calvac Paving Bay Area

3 – Strength and Durability


Due to its flexible composition, asphalt is less inclined to crack. This is a bonus for climates with frequent freeze-to-thaw rhythms (not a factor we have to highly consider here in the Bay Area). 

Although asphalt is durable, it is less solid than concrete. This can often result in a need for more ongoing maintenance. 


Since concrete is less pliable than asphalt, it is more prone to cracking – especially when regularly exposed to extreme temperature variation in a given climate. Although more likely to crack than asphalt, the strength and durability of concrete contributes to less maintenance over time, and a longer lifespan than asphalt. 

4 – Cost


In general, asphalt has a lower installation cost than concrete. Contributing factors include asphalt materials and the fluctuating price of crude oil, as petroleum serves as a base for asphalt.


Concrete is typically more expensive to install than asphalt. There are a number of customization options with concrete (finish color, texture, stain, etc…) and this can contribute to an increased price tag. 

Calvac Paving Bay Area

5 – Maintenance


Although lower installation cost is a benefit of using asphalt, property owners need to understand that regular maintenance and repairs will be a reality. In order to extend the longevity of asphalt, it should be sealed every three to five years. Regular patching and resurfacing will also be required. When properly installed and regularly maintained, asphalt has a lifespan of up to 30 years. 


Initially, concrete has a higher installation cost than asphalt. Factors which contribute to the initial cost of concrete include color tint, stain, and stamping or engraving on the concrete. Although concrete has more upfront costs than asphalt, maintenance is more minimal and costly. When cracks are properly repaired and maintenance is promptly managed, concrete has a lifespan of up to 50 years. 

As you consider the goals for your paving project, take the time to consider your needs in the areas of materials, appearance, strength and durability, budget, and maintenance. As you do this, your preference for asphalt or concrete will become clear. We encourage you to reach out to your local asphalt and concrete company for additional guidance and pricing. If you are in the Bay Area, Calvac Paving has the experience and expertise you need to make your paving project come to life!

What’s the Difference Between Cement and Concrete?

Calvac Paving in San Jose concrete work

One question we hear a lot at Calvac Paving, usually from private homeowners and people who don’t work in construction, is what the difference is between cement and concrete. After all, many people call concrete trucks “cement mixers” and refer to the finished product as “cement.” The problem is, this isn’t just inaccurate, but it can cause a lot of unnecessary confusion between contractors, engineers, and the general public. To explain why this matters, let’s start by taking a closer look at how cement, the key ingredient in concrete, is made.

Everything You Need to Know About Cement

Cement is not the only ingredient in modern concrete, but it is the base agent. The most commonly used type of cement is known as Portland cement, because of the end product’s resemblance to an ancient building material found on the island of Portland, off the British coast. This method of creating concrete was first patented by an English stonemason in 1824, meaning modern cement is two hundred years old! Portland cement is created by burning and then grinding down a mixture of limestone and either shale or clay. This forms a fine, gray powder with hydrophilic properties, meaning it attracts and binds readily to water. When it is mixed with water and allowed to cure, it creates a stonelike surface, similar to plaster of Paris but far stronger and less brittle. The problem with hydrophilic cement is that it’s both fairly volatile in terms of how readily it reacts with water and can take a long time to cure. Because of this, it has to be carefully stored in a cool, dry place to keep it in powder form until it’s ready to be made into concrete. Admixtures that help reverse the cement’s hydrophilic properties are often added to the matrix during the mixing stage to reduce the cure time and boost its strength, flexibility, and resilience.

How Concrete is Made

Now that we know how Portland cement is made, it’s time to take a look at how concrete is created, which is really quite simple. By adding water, aggregates from fine sand to large crushed rocks, and in many cases chemicals to the Portland cement, you can create a concrete mix that will meet target strength and flexibility profiles, a specified air content range, and even make concrete in different colors! The quantity and percentage of cement, water, and aggregates of different sizes to be added will depend largely on what the concrete mix is intended for. On a freeway bridge where asphalt paving is not desirable, you will probably want a fairly lightweight, smooth mix. This typically requires more sand and chemicals with a larger quantity of smaller aggregates than an ornamental walkway, which obviously won’t be expected to stand up to the same stresses as a highway.  The various dry materials are loaded onto the concrete truck at a batch plant. Each truck is supplied with a batch ticket, which shows the percentage and weight in pounds of the various dry ingredients and chemicals. Once the dry materials are loaded, the driver will add a specified amount of water. With the water added, the concrete has to be constantly agitated by rotating the drum to keep it from hardening in transit. If the mix cures on the truck, it’s nearly impossible to remove. If you’re a fan of the show Mythbusters, you may remember they did an episode where they tested a myth about using dynamite to clean out a drum full of concrete that had been set up en route to a job site. Yes, concrete really does get THAT hard!

Concrete on the Jobsite

Once the mixture reaches the placement location, the tickets are often collected by the technicians who sample and test the concrete to ensure compliance with the project parameters. These technicians may be employed by the company supplying the concrete, a private third-party laboratory, or local, state, and federal authorities. About halfway through the load, if required, they will take a sample from the truck for testing.

Some Common Concrete Tests Include:


  • Slump Test: Too little or too much water means the concrete may not perform to specifications when it hardens. Many companies send their concrete from the batch plant with the minimum water possible added, because it’s far easier to add water to a drier load than it is to get water out of an overly wet one! A slump test is performed by using a steel cone to form the raw concrete into a 12-inch-high cone and then pulling the steel form away. Upon removing the cone form, the concrete cone should fall. By measuring the amount the cone falls, or “slumps,” when the cone form is removed, the technician can determine whether the concrete’s water concrete is within the proper range for the mix design to perform as expected.
  • Unit Weight and Air: These tests allow a laboratory to extrapolate from a given sample about whether the mix design as loaded on an individual truck is within the parameters specified for a given project or application. The air test is particularly important and most commonly done on high-traffic roadways which will receive a lot of exposure to the elements and temperature extremes, because too much air in the mix may allow for air bubbles to form, allowing moisture and frost to infiltrate the matrix and over time, break it up.
  • Cylinder Tests: When you hear someone talking about “pulling cylinders” on a concrete pour, it’s almost certain they’re talking about this test. The raw concrete is formed into cylinders of a specific size and depth using plastic molds and allowed to cure onsite in a temperature-controlled environment such as a cooler for at least 24 hours. After this, the cylinders are taken back to the lab, “stripped” out of the molds, and placed in a high-humidity environment to cure until it’s time to break them. Commonly, a set of four cylinders is taken from a given load. This includes one to be broken at 7 days, at which point the concrete mix should meet 70% of the intended break strength; 2 to be broken at 28 days when the concrete should have reached 100% of the specified break strength; and one cylinder to be kept on hold in case one of the 28-day breaks fails to meet the specified strength, in which case it will be broken at 56 days or as directed by an engineer. Note: Your project may have different requirements, so be sure to check with the Engineer of Record for the exact testing protocols!

Once these tests and any others the project specifications require are done, the concrete can be certified as meeting the project parameters and construction can continue.

Putting It All Together

Now that you know how cement and concrete are made, you can see they’re not the same thing. It’s easy to understand why some people persist in calling concrete mixers “cement mixers,” even though this isn’t entirely accurate. It’s also obvious why some people stick with calling concrete “cement,” since it’s the Portland cement that cures and makes concrete a durable building and paving material rather than just a jumble of wet rocks and sand. However, it’s important to understand that when you ask for “cement” and you mean “4500-PSI blue concrete for an exposed-aggregate walkway,” you’re at the minimum going to cause some confusion and brand yourself as an amateur. At the worst, you’ll wind up with a pile of dry Portland cement, which on its own will certainly do you no good when you’re building a roadway or a sidewalk.

But Now That You Know And Understand The Difference, You’re Far Less Likely To Have That Problem—And You’ll Sound Just Like The Experts!

Bay Area Golf Course Asphalt Repair

Bay Area Golf Course Asphalt Repair

Revitalizing Poppy Ridge Golf Course!


At Calvac Paving, we know a thing or two about asphalt repair and Golf Courses.

So when Poppy Ridge Golf Course called us to bid on a project to rehab an extensive areas of failed asphalt encompassing the road leading to the golf course and the parking area itself, and to reseal and restripe the parking area and drive entrance, we were pleased to submit our expertise and cost for consideration. Soon thereafter, we learned we had been awarded the project at 4280 Greenville Road in Livermore.
To achieve the repair, we provided 4” asphalt repairs and two coats of seal followed by restriping. This required excavating the failed asphalt and recompacting the subgrade beneath the asphalt paving. Then the hot mix asphalt needed to be placed in two 2” layers, or “lifts,” using 3/4” asphalt on the base lift and ½” medium asphalt on the surface lift. Covering 4,000 +  square feet of surface area. This ensures strength, flexibility, and density within and between the asphalt layers, while minimizing air voids which can facilitate water infiltration and lead to premature asphalt failure over time.  
Once the subgrade and the lifts had been individually compacted, we provided two coats of Reed and Graham’s OverKote, an asphalt emulsion seal for asphalt which incorporates a latex additive. This step gives a smooth, finished appearance to the asphalt, adds surface resiliency and increases water and dust resistance, extending the operational lifespan of the asphalt. The staff and patrons of the golf course were extremely cooperative and understanding of our schedule and the project went very smoothly.
We’re proud to announce that Poppy Ridge Golf Course has already recommended us for similar projects on the strength of our work here, and we’re excited to be able to demonstrate the quality and efficiency of our work once again as the leading Bay Area Asphalt repair company.
Calvac Paving has been serving the Bay Area since 1972, and we’re proud to bring the same great results to every project we work on.

8 Signs Your Asphalt May Be Failing

8 Signs Your Asphalt May Be Failing


Asphalt is a very versatile and durable paving material. Its resilience and flexibility make it an ideal surface for everything from eight-lane superhighways to driveways to parking lots. However, asphalt does require care and maintenance to function at peak performance, and it can fail for several reasons. If you see any of these warning signs of failing asphalt, quick action can save you a lot of time, money, and hassle. Here are eight signs your asphalt may be failing—and what you can do to fix them!  

1.  Alligatoring

Alligatoring is called that because of its appearance: interconnected cracks that look like alligator skin. It is an indication of load-related deterioration which could be caused by a weakened or improperly compacted subbase material, excessive traffic loading, inadequate pavement thickness, or a combination of these factors.  

2.  Edge Cracks

Edge cracks are found within 1-2 feet of the outer edge of the asphalt surface, running longitudinally, or roughly parallel to the outer edge. These cracks are caused by improper support of the paving surface at the margins.  

3.  Reflective Cracks

Reflective cracks most typically form in joints or areas of concrete or asphalt paving which have been previously repaired, such as with crack sealing or where a temporary corrective overlay has been placed to relieve stress on deteriorated paving. These cracks form because of continuing movement of the old pavement due to continuing traffic load.  

4.  Slippage Cracks

Slippage cracks are easily identifiable because of their crescent shape. They occur either due to poorly bonded pavement layers or an asphalt mix design which is insufficient to the demands of the traffic patterns. These cracks appear because of forces applied by turning or braking vehicles, which cause the pavement to move slightly at first but with accelerating damage to the surface the longer the underlying cause goes uncorrected.  

5.  Rutting And Depressions

Ruttingis caused by weakness of the subgrade or base soil layers, instability of an asphalt mix, insufficient pavement thickness, or poor compaction. Rutting is a linear, surface depression of the wheel path caused by deformation or consolidation of any of the pavement layers or subgrade. Depressions,also known as birdbaths, are localized areas of pavement surface failure caused by poor initial construction techniques that undermine the asphalt over time. These may occur on their own or in conjunction with other failure indicators. If left unchecked, depressions can become potholes(see #8).  

6.  Asphalt Patch Failure

These failures are easy to spot because they’re very localized to the area where a patch was placed, and characterized by unevenness, deflection, or stress cracking along the perimeter of the patch. They are caused by either not fully removing the damaged area to be patched, or not allowing a minimum of one extra foot around the perimeter of the patch area to ensure the patch is bonding to an uncompromised surface. The rate of patch deterioration is influenced by materials selection, compaction, and the quality of the surrounding pavement as well as the underlying subbase. While the latter is not typically visible, adding one additional foot around the patch can help patches last longer and function better under load.  

7.  Raveling

Raveling is caused when the aggregate particles in the asphalt cement wear away under traffic forces. This condition suggests either that a poor-quality mixture was used or the asphalt surface has hardened enough to no longer be supple and flexible.  

8.   Potholes

These bowl-shaped holes are caused by localized disintegration of the pavement surface. Potholes are usually the result of another type of distress that has not been properly addressed. Segregation, failed patches, and cracks can all lead to a pothole over time. Weak spots and localized areas of improper or insufficient compaction in the subgrade or subbase, or poor asphalt mix designs, can accelerate the degradation of the pavement surface and the formation of potholes.   When you notice indications of paving failure, bring in an experienced paving contractor as soon as possible to restore the surface and minimize downtime, expense, and the risk of further, more severe failure in the future. Calvac Paving has been proudly serving the Bay Area and beyond for over 45 years, and we’d like to put that experience to work for your next paving repair or new construction project.

7 Signs Your Parking Lot Paving Needs to be Repaired

7 Signs Your Parking Lot Paving Needs to be Repaired


Asphalt pavement is one of the most durable and resilient materials currently used in modern construction. It’s easy to place, maintain and recycle when its service lifespan has expired, helping to reduce manufacturing costs and greenhouse gas emissions associated with asphalt paving production. Asphalt surfaces are also very flexible relative to other paving materials, which is just one reason why asphalt parking lots have become so popular. But, like any other construction material, asphalt and concrete paving don’t last forever. A well-placed asphalt surface can last 10-20 years or more with proper pavement maintenance. As we move into the wetter, colder months, you’ll want to be on the lookout for these 7 signs your parking lot needs repair.  

1.  Look For Cracking And Crumbling Edges.

You’re most likely to see these signs of asphalt deterioration around joints in the parking lot paving and the curb and gutter areas of industrial parking lots and asphalt driveways, although they can occur anywhere. When this happens, it could indicate that people are driving too close to the edge, the asphalt is not properly supported at the edges or the asphalt is beginning to age out of effective service. If not sealed or repaired, the cracks can spread throughout the entire surface. Crack sealing early can help extend the life and performance of the asphalt surfaces.  

2.  Potholes And Sunken Areas

These commonly occur when water seeps into cracks in the parking lot’s surface. Over time, the water undermines the subbase, causing the paving in that area to sag and crack. One key symptom of an incipient pothole is the presence of pooling water on the surface. If you notice this, a spot asphalt repair can help prevent larger and more costly problems later.  

3.  Alligator Cracks

Alligator cracking, named for its distinctive appearance, is a sign of too much stress on the asphalt. If your asphalt surfaces look like the skin of an alligator, it can indicate the subbase was improperly prepared by the original paving contractor and/or the pavement is routinely subjected to heavier traffic than it was designed to withstand, such as parking large trucks on a residential driveway. When you see this, you need parking lot and driveway repair or replacement right away.  

4.  Oxidization

The binding agents in asphalt which give it its flexibility and strength don’t last forever. In fact, from the moment asphalt is laid, the sun, wind, water, weather, and oil and chemical leaks from vehicles begin to eat away at them. This is why asphalt’s color fades from black to gray and the aggregate begins to peek out of the surface. Depending on the size of the area and whether other signs of damage are present, asphalt seal coat, asphalt milling, and parking lot resurfacing may all need to be considered.  

5.  Improper Drainage

Evidence of improper drainage can be an early sign asphalt repairs are needed. If water can’t drain off your parking lot or driveway it can damage the asphalt surfacing and cause larger problems later. Blocked storm drain inlets can lead to damage as well, so it’s important to inspect them regularly and make sure the runoff from your lot or driveway can go to where it’s intended.  

6.  Faded Or Illegible Striping

Proper parking stall and line marking make your property look better and more user-friendly. It’s also a requirement of the Americans with Disabilities Act. In addition to directing traffic, striping often works as a sort of visual canary for indicating potential issues which might otherwise go unnoticed. If your parking lot’s striping is looking worn, difficult to read, or hard to understand, you need to take a closer look at the entire area for other potential issues.  

7.  Time

If you can’t remember the last time you had any repairs or maintenance on your driveway or parking lot, it’s probably time. For best results, your asphalt surfaces should be seal coated at least every 4-5 years to help keep them looking their best and preventing chemicals, motor oil, and water from infiltrating the surface. If there are no major issues with the asphalt surfaces, minor crack sealing and spot repairs can also be made before sealing the surface again. It’s also a good opportunity to update your parking layout and striping to comply with ADA guidelines if they don’t already!     Keeping your asphalt paved surfaces in good repair isn’t just about making your property look and perform its best. Driveway or parking lot problems could also present ADA compliance issues with hefty associated fines and even open your company to workers’ compensation claims or civil lawsuits arising from injuries and vehicular damage. By making timely preventative asphalt repairs you can save time, money, and worry while presenting a more professional face for your business.

7 Reasons Why Quality Asphalt & Paving Is A Must for Bay Area Commercial Properties

7 Reasons Why Quality Asphalt & Paving Is A Must for Bay Area Commercial Properties

Calvac Paving in San Jose commercial services

Have you ever thought about the signals your paving might be sending? Most people don’t, but properly executed concrete and asphalt commercial paving can make a big difference in how your property is perceived, from the initial impression people receive just driving by to potential customers or even buyers. 

If your property is used for regular commerce, such as a shopping center, big-box store, church, or apartment complex, you may find you don’t entice the sort of clients and visitors you’re hoping for if your asphalt surfaces aren’t up to par. 

Even worse, it could adversely affect the bid numbers your property receives if you decide to sell!

If you’re noticing cracking, discoloration, warping, areas of exposed aggregate, faded striping paint, or other common signs and symptoms of asphalt and concrete failure, you might be tempted to just ignore it—or worse, try to figure out a fix for satisfactory asphalt repairs with the staff and materials available to you and your company. 

But DIY asphalt repair isn’t always the best way to deal with problems like this. If they’re not dealt with by reputable asphalt paving company contractors, you could be left with an even bigger problem than you started with—and your customers, visitors, and potential buyers might be scared off by poorly placed asphalt paving or improper asphalt maintenance.

Calvac Paving is the asphalt company the Bay Area and Northern California trust for all your concrete and asphalt construction needs, delivered on schedule and on budget. 

So if the points above haven’t convinced you that you really do need the help of professional asphalt paving companies to make sure your asphalt driveway, parking areas, and roadways are up to scratch, here are seven reasons why quality asphalt paving is a must for commercial property owners!  

1. Enhances Curb Appeal

Commercial asphalt paving contractors can help improve the aesthetics of your property. Quality asphalt paving will enhance the curb appeal of your commercial property, making it look more professional and attractive to potential customers. Whether it’s a convenience store or a chain of community centers, even small cracks in your pavement can add up to high costs in lost revenues and interest for your business.

2. Boosts Property Value

Quality commercial asphalt paving is an investment that can increase the value of your commercial property. It can also make your property more appealing to potential buyers or tenants now and in the future.

3. Provides Safe and Smooth Surfaces

A quality commercial asphalt paving contractor will provide asphalt installation that delivers a smooth and level surface that is safe for pedestrians and vehicles and retains striping and marking paint at maximum visibility for a longer period too! A poorly paved surface can be dangerous, causing accidents and damage to vehicles. It’s also an ADA compliance infraction that could rack up big fines or even shut your business or property down if it’s not corrected.

4. Reduces Maintenance Costs

Quality asphalt paving can help reduce maintenance costs. A well-paved surface is less likely to develop cracks or potholes, reducing the need for frequent repairs.

5. Improves Drainage

Commercial asphalt paving contractors can design, build, and install a drainage system that prevents water from pooling on your property. This reduces the risk of damage to your pavement and prevents accidents caused by slippery surfaces. It also helps extend the life of your asphalt paving, keeping it looking and performing great for longer, reducing the future cost of maintaining and repairing your asphalt over time.

6. Enhances Sustainability

A quality commercial asphalt paving contractor will use sustainable materials and techniques to create long-lasting pavement. This reduces the environmental impact of construction on your property and the world around us and helps you meet sustainability goals. Going green, or at least greener means everyone wins!

7. Increases Customer Satisfaction

A well-paved parking lot or driveway can help improve customer satisfaction. It provides a positive first impression of your property, making customers feel more comfortable and safer while visiting your business while sending a clear, simple message: “We’re up to the job!” This is a crucial first step in the customer experience because if your facilities don’t look like they’re up to par, why would their expectations include the excellent, even exceptional, customer service and results you and your experienced staff strive so hard to provide?

Frequently Asked Questions About Why Quality Asphalt Paving is a Must for Commercial Property Owners

Calvac Paving is the asphalt paving contractor commercial businesses and government entities in Northern California trust for parking lot and driveway paving that lasts longer, as well as roadways that will stand the test of time!

Question: What Is A Commercial Asphalt Paving Contractor? –Reynaldo, San Jose, CA

Answer: A commercial asphalt paving contractor is a professional who specializes in the construction and maintenance of commercial properties such as parking lots, driveways, and roads using asphalt, as well as commercial paving and coating operations for other applications. But caveat emptor! Not all asphalt commercial paving companies are created equal. A commercial contractor who can handle a simple, minor repair job that only requires a touch-up on asphalt sealcoating to bring the surface back to life again may find themselves out of their depth on a job that requires a complete tear-out and reinstallation because the cracks have infiltrated through the entire asphalt mat, allowing in water, frost, and biological and environmental contaminants that can undermine asphalt’s flexibility and resilience. It’s important to always check the expertise of the company you’ve chosen for your commercial paving and coating needs, so you know you’ll get great, durable results that last far beyond the day the contracting company leaves the site!

Question: What Is The Typical Lifespan Of An Asphalt Surface? –Artie, Los Gatos, CA

Answer: The typical lifespan of an asphalt surface can vary depending on the quality of materials used, how well the ground preparation was executed before the final mat was introduced, the amount of traffic it receives, and the level of maintenance it receives. Generally, an asphalt surface can be expected to last between 15-20 years with proper care and maintenance.

Question: What Services Do Commercial Paving Contractors Offer? –Jeanette, Santa Clara, CA

Answer: In general, a reputable, established commercial paving company will typically offer a range of services, including new construction, repair, maintenance, and replacement of asphalt surfaces. Commercial contractors can also provide asphalt and concrete paving repair services, such as seal coating, striping, and crack filling, to extend the service life of your paving, so it looks and works better for longer.

Question: How Do I Choose A Reliable Commercial Asphalt Paving Contracting Company? –Chuck, San Francisco, CA

Answer: To choose a reliable commercial asphalt paving industry contractor, you should look for a company that has a good reputation, proper licensing, insurance, and experience in the field. You can also ask for references and check reviews from previous clients. If available, review the project gallery of previously completed projects to make sure the results they’ve delivered in the past are in line with your expectations for the future of your project. It’s even better if you can independently contact communities or municipal office personnel, such as a project manager, who has interacted with the company in the past and can give you an unvarnished review of your paving contractor’s services.

Question: What Factors Affect The Cost Of Commercial Asphalt Paving? –Thomas, Hobart, CA

Answer: The cost of commercial asphalt paving can be affected by various factors such as the size, scope, scale, and complexity of the paving project, the quality of materials used, the location, and the equipment and labor required for the job. For example, a job that only requires a pump truck with a single two-person paving team to dispense seal coat or crack sealer is going to cost a lot less money than one that requires a lowboy, pavers, a parade of asphalt delivery trucks, a front-end loader, and steel-drum and rubber-tire rollers, plus an experienced and seasoned roster of multiple paving crews to run and manage all this equipment. In general, residential driveways need a lot less equipment than most parking lots, and most parking lots (excluding schools and universities) typically require less equipment than roadway construction does, which obviously has a large impact on the pricing range you can expect for your job.

Question: How Long Does It Take To Complete A Commercial Asphalt Paving Project? –Ilsa, Sunnyvale, CA

Answer: The time it takes to finish a commercial asphalt paving project depends on the size, complexity, type, and requirements of the project. However, with proper planning and preparation, most projects can be completed anywhere from a day or so after starting to a few weeks, in the case of large industrial projects. This does not include the time to survey, plan, make sure the necessary crews, equipment, and materials are reserved, set up any necessary traffic controls, and similar “pre-work” logistics tasks that need to be done but often get overlooked when considering a deployment and execution schedule.

Question: I Manage The Development Of Townhouses, And I’m Considering Having My Maintenance Staff Work On Some Paving Problems I’ve Noticed. What Are The Benefits Of Hiring A Commercial Asphalt Paving Contractor? –Karen, Palo Alto, CA

Answer: While going the DIY route to stay within budget can be very tempting, it’s almost never the best way. What videos from YouTube or Instagram often don’t tell you are things like why this specific solution worked, or that one didn’t. They also don’t address hidden problems you might encounter trying to do the work yourself, such as water or frost infiltration into the mat, which can compromise its performance and presage more serious problems in the making, which may mean replacement rather than repair, is the right call. Hiring a commercial asphalt paving contractor at the outset can help ensure that your project is completed efficiently and to a high standard. They can also provide professional advice and guidance on the best solutions for your specific needs and situation. Obviously, there’s a lot more that goes into helping keep your paving looking and working great than just keeping it clean.
