How to Raise Sunken Concrete

In the past, contractors relied heavily on mudjacking to lift concrete that had settled over time. Mudjacking is an easy, affordable way to lift concrete by pumping a slurry below a slab through holes at the surface. However, mudjacking isn’t the perfect solution for Atlanta concrete lifting because the material pumped below is extremely heavy and could create additional settling as a result. 

At AquaGuard, we use PolyRenewal® injection in Atlanta for properly lifting concrete slabs to a more even, stable position while using less weight than the traditional mudjacking or slab leveling technique. PolyRenewal® can repair sunken concrete slabs, such as driveways, sidewalks, patios, basement slabs, and more. 

How Does PolyRenewal® Lift Concrete?

The PolyRenewal® System utilizes high-density polyurethane foam to stabilize and lift concrete floors and foundations. The PolyRenewal® process starts with drilling penny-sized holes in the concrete slab. From there, a structural grade polymer is injected into the void. Once the void is filled, the expanding properties of the polyurethane foam begin to lift the slab. The holes are grouted and sealed as part of the final step, and the concrete slab is completely repaired.

How PolyRenewal® compares to other concrete lifting techniques

In the past, mudjacking was considered the best way to fix sinking concrete stairs, driveways, sidewalks, etc. However, mudjacking didn’t completely or permanently solve the problem, which is why AquaGuard turned to PolyRenewal® to fix your sinking concrete problems. Take a look at why PolyRenewal® is actually a better solution for your concrete slab settlement problem.
