A company's sidewalk was unenven and craking in front of their building. So they called our team and we installed PolyLevel, a system that fixes settlement issues in concrete slabs. A polyurethane foam that expands and has a high density is used in order to raise the concrete. The process is quite simple and is done by drilling small holes into the concrete and then inserting the foam into the holes. Also, the PolyLevel system is waterproof and long-lasting.
