Don't ignore your sinking concrete! As soon as you start to see settlement or a trip hazard, address the area with a professional right away to avoid an accident. Our team raised an entire concrete porch area located in Phillipsburg, New Jersey with our concrete raising system known as, PolyLevel. Since this concrete porch was in great condition with no cracking, our team injected the PolyLevel Foam underneath, to fill the voids and raise the slabs back towards their original level.
