Sinking and heaving asphalt can be disastrous to your asphalt pavement. Here is why that happens and how to fix it.


Repairs can take different forms depending on the extent of the damage. After we assess the problem, we can decide on the best course of action that will allow you access to your paved surface as quickly as possible. We can get to cracks as soon as they appear and keep your pavement from sinking. Some sections may have to be removed to facilitate the repairs. Sometimes it is only necessary to remove the top layer, but we may have to dig deeper if there is a problem with the subgrade. Of course, regular maintenance can keep your paved areas strong for years. Services like sealcoating and crack routing can help to prevent water seepage so that the top layer will keep holding up. You can do your part by keeping an eye on your asphalt surfaces and calling us when you notice a problem.

Heaving (From Frost)

Frost heave is a common problem in colder climates. Many people are watching their asphalt heave as the winter temperatures fluctuate. The cause is the freezing and thawing that comes with above and below freezing temperatures that start the formation of ice lenses. Ice lenses form in the soil under the asphalt and push the surface up as they grow. They are fed from every direction and will continue to grow as long as there is an available water supply. Silt or clay soils are more susceptible to frost heave than better draining soil mixtures. Many people never notice the winter frost heave on their older driveways that have sunken at the garage; but once they repave and have a surface that is even with their garage floor, the heaving is much more noticeable. Chances are, after winter your pavement will need maintenance and repairs. Proper initial installation is extremely important in decreasing the number of repairs and damages frost and winter conditions can cause. A base that is too thin, or one with extremely fine soil can be more susceptible to water and frost heave damages. A parking lot lacking proper drainage can also be a leading factor in excessive asphalt damages and/or surrounding structure damages.
