Homeowner noticed their front porch slabs had settled creating a small gap where the slab and home's foundation use to meet. Instead of replacing the entire porch, they contacted Quality 1st Basements to lift and level the existing slabs with our PolyLevel Foam Solution. Our team drills small holes into the concrete slab. Next, using special equipment, PolyLevel is injected underneath the slab to fill voids and provide additional support to the weak soil. The foam expands lifting the slab and once raised, the foam begins to harden, permanently stabilizing the concrete porch.
