PolyLevel Injection Holes
The 1/4" holes are small and easy to fill afterwards. The concrete is lifted and there is little sign the repairs were even made. Very clean and efficient installation.
Sloping Concrete Patio
Prior to installing PolyLevel, the concrete patio was sloping towards the house. Water would build up and run under the sliding glass door.
Raising the Concrete Slab
Before injecting the PolyLevel, the production crew likes to use a slab jack to lift the slab to the desired location. They then inject PolyLevel to fill the voids and stabilize the concrete.
