Check out how we fixed this sinking and settling concrete porch area. Quality 1st Basement Systems met with a homeowner in Phillipsburg, NJ to provide them a solution for the unsettled porch area they had been dealing with for quit some time. Our team used Polylevel to lift, level and stabilize each concrete slab area. Stabilizing the concrete will prevent future movement and settlement since it fills the void between the weak soil and concrete. This environmentally friendly and waterproof, polyurethane foam is the perfect solution for settling concrete that is not crumbling.
