Pool Deck Repair in Hopewell, NJ

This Hopewell NJ homeowner contacted BQ Basement Systems regarding a huge tripping hazard along his pool deck. Our team performed saw this significant gab and knew our PolyLevel concrete leveling system was the perfect solution. Voids had formed underneath the concrete slabs do to erosion of the soil under the slab. One specific slab had sunk and creating a huge gap between the level surface and the concrete slab. A sinking slab is especially dangerous around the pool because it is a major tripping hazard. BQ installed our PolyLevel System as a solution. Our team drilled holes through the slabs, filled the voids with Polyurethane, which lifted the area that had sunk and created a leveled stabilized surface. This homeowner could not have been happier and was ready to spend Summer months by the pool!
