Can You Lay Tarmac on Concrete?

Posted on: July 23, 2022

Many people wonder: Can you lay tarmac on concrete? There are several reasons why it can be problematic. In some cases, the concrete may be heaving, cracking, or buckling. In other cases, it may simply be insufficient to cover the entire area. In the latter case, it may be necessary to lay the asphalt on top of the existing one. Ultimately, it is a matter of taste and preference, but concrete issues can damage a new layer of asphalt.


Heaving when laying tarmac onto concrete is an issue that can cause significant damage to a car’s suspension and tire. It is a common problem in California and other climates, and can be prevented by following a few simple tips. To start, make sure that your concrete is compacted properly. If not, heaving is likely to occur. And if it does, it could result in damage to the new asphalt you lay on top.

Asphalt heaving, also known as frost heaving, is a common problem in the winter in the Westchester/Putnam Counties. This happens when moisture trapped underneath asphalt freezes. As a result, the asphalt pushes up, or heaves, causing cracks in the surface. These cracks look like alligator skin, so if you do not get them fixed, your driveway is likely to suffer further damage.


In some cases, cracking when laying tarmac on concrete may be a sign of a problem. Cracks may continue to form after paving or sawing. Some cracks may be visible in the early stages, but later cracks may appear, suggesting something is restricting the movement of the concrete. If this is the case, further inspection of the concrete surface will be necessary. Fortunately, cracks may not be serious and can be repaired without causing further damage.

Uncontrolled cracking can be caused by differential thermal contraction. Cracking can occur if the temperature of the concrete varies from its surface to the depth below. This sudden drop in temperature can result in excessive surface contraction. This is particularly common during the spring and autumn when the air temperature is relatively higher. During the summer, when the air temperature is lower than the air temperature, the concrete may begin to contract.


It is common to see wavy sections of concrete pavement. This can be a result of improper installation of the sub-grade and failure to repair alligator cracks. Heavy vehicle traffic can also contribute to buckling. Buckling is common in communities where heavy vehicles drive across the pavement. Here are some tips to avoid this problem. The following tips will help you prevent buckling. These tips will help you to avoid buckling on your concrete driveway, walkway, or street.

First, know the causes of buckling on concrete roadways. When concrete and asphalt are mixed, the mixture reacts differently to changes in temperature. In the summertime, for example, the ground can reach a temperature of 130 degrees. When this happens, asphalt and concrete pavements may buckle. In this case, the repair crews push the concrete up again and place a temporary patch. They will have to come back to repair the buckling concrete.

If you’ve ever driven on a roadway with buckling asphalt, you know that it’s dangerous for drivers. Buckling pavements can send cars flying off the road and cause accidents. That’s why proper subsurface preparation is essential before placing asphalt on concrete. If you’ve noticed buckling asphalt on your concrete, you’ll need to have it removed and replaced by a professional. Read on for more information.

Before pouring your concrete, make sure the sub-surface is properly prepared. If the asphalt is cracking, then there’s probably something wrong with the ground underneath. The asphalt should be at least 5 inches thick and sit on a sub-base of at least eight inches of gravel. You can check the depth by drilling into the asphalt before installing the concrete. If the asphalt is too deep, you may have to scrape it off.

Cost of tarmac

If you’re looking to cover a large area of concrete with tarmac, there are some factors that will determine the total cost. The base price for tarmac depends on many factors, including the size of the area and the type of driveway you’re installing. The price will be higher for large areas, as more labour and material will be required to cover the area. You can save money by buying in bulk, which is common among building suppliers.

When choosing a driveway material, tarmac is usually the most expensive, but it’s also the most durable. Compared to gravel and other paving types, tarmac lasts the longest. Plus, the material is easy to maintain, and requires little ongoing maintenance. You can also get a DIY solution by installing a gravel driveway. Resin driveways are another option. These don’t require any sweeping or weeding, making them perfect for homeowners who want a low-maintenance driveway.
