Raising a Sinking Patio in Ballwin, MO

A concrete patio was sinking in Ballwin, MO, causing the step leading up to the house to separate from it. To solve this issue, the PolyLevel System was installed. This will stabilize, lift, and level the concrete slab with high-strength polyurethane foam. Pea-sized holes were drilled into the concrete and the foam was injected to fill the void underneath. This installation technique allows the foam to expand as it cures, precisely lifting the slab back up. This will improve the safety of the patio and restore peace of mind for years to come!
