Driveway Repair & Concrete Leveling

Why Do Concrete Driveways Sink and Crack?

Concrete surfaces such as driveways, sidewalks, and walkways experience a lot of wear and tear. If the soil supporting the concrete slab becomes weak, the concrete will crack and sink. Other factors that can cause concrete to sink include:


A common cause of sunken concrete is erosion. Erosion washes away soil from under your driveway, creating a void under the concrete slab. Your driveway can begin to sink in areas where the soil has been washed out. 

Poor Yard Drainage

Clogged gutters and downspouts that are not installed correctly and poor yard drainage can make erosion worse. A heavy load, such as an RV that’s kept in your driveway, can cause sections of the driveway to sink and crack over time. 

Badly Compacted Soil

If you have a newer home with a sinking driveway, it could be because the ground around the house is settling or the base of the driveway was not compacted properly. A sinking driveway near your garage can lead to foundation cracks and expensive damage over time.

We Can Raise Your Uneven Concrete Driveway

While surface problems can likely be patched, this won't fix the underlying settlement problem and more cracks can form in your driveway. 

Although do-it-yourself repairs might be less expensive, they can be messy, require special tools and equipment, and it can be as long as 30 days before you're able to use your driveway again. No matter what's causing your driveway to sink, we can fix the problem fast and prevent further sinking with our concrete leveling services.

Lift and Level Your Driveway Permanently with PolyLevel®

Do you have a concrete driveway that’s cracked, sunken or uneven? NSquare, Inc. can quickly and effectively repair your driveway by leveling the concrete, rather than tearing out and replacing it. We use a process called PolyLevel® to raise the existing concrete slab back to its original position. 

PolyLevel®: the Permanent Concrete Repair Solution You Can Trust

PolyLevel® is a less disruptive alternative to mudjacking. The polyurethane injection expands and penetrates all voids, creating a supportive pillow of protection. The PolyLevel® process is less invasive and fast-acting – the expanding polymer reaches its final strength and is ready to support weight within 15 minutes, as opposed to mudjacking which takes a whole day.

The Process:

First, your contractor will drill small holes in the slab. Then they will inject a high-density polyurethane through the holes. The polymer will spread beneath the slab and lift it. Finally, the holes are patched, and the cracks are filled. You'll be able to use your driveway within one day.

Driveway Repair: Before and After

This concrete driveway had sunk about two inches in front of the garage. Using PolyLevel®, we were able to raise the concrete, making the driveway level with the garage entrance. No more ugly sunken driveway!
