Repairing Sinking and Heaving Asphalt

man walking in a parking lot that needs repair

Asphalt can be your best friend or your worst enemy--and sometimes, a little bit of repair and maintenance makes all the difference. One frustration you might have with your asphalt is the "sinking and heaving" problem--a parking lot that dips in one corner and/or lifts way too high in another, creating an uneven and unsafe surface. Let's find out what you can do to solve this problem!

The Thing About Asphalt

The thing about asphalt is that it's designed for high-traffic areas, which means that it must be safe for everyone using it. If someone were to trip in your sinking and heaving parking lot, you could be looking at legal fees that would definitely break the bank--and, all cost issues aside, you want customers and employees to feel safe and comfortable approaching your business. (On top of that, the worn-out sidewalk just doesn't look professional.)

So what can you do? The truth is that commercial repair and maintenance is always going to be cheaper than the problems caused by a poor parking lot--so it's best to call in the experts to help diagnose and solve your asphalt issues.

Causes of Sinking and Heaving

Once you've decided to repair your sinking and heaving asphalt, it's time to find out what caused the damage in the first place. Here are some common causes of this irritating issue!

Soil Problems

The soil under your parking lot needs to be properly compacted. If it isn't, one bad freeze/thaw cycle could be enough to change the levels and balance, making your asphalt completely unstable.

Too Much Moisture

Too much moisture, whether from weather or irrigation or poor drainage, can cause soil erosion--which, in turn, causes your parking lot to sink into the resulting gaps.

Not Enough Moisture

Interestingly, while wet conditions can spell bad news for your asphalt, dry conditions can be just as damaging. When the ground is too dry, parking lots can begin to heave and become unsafe.
