(952) 818-7659 PolyTech offers the industry's leading technology for concrete lifting and concrete leveling projects. Our trained professionals treat your sunken concrete with high density, polyurethane foam injections and fill voids using our state-of-the-art geofoam fill. Lifting concrete with polyurethane foam, also known as polyjacking or foamjacking, is up to 50% cheaper than re-pouring concrete. It is a long-term repair, not a temporary fix like traditional slabjack methods such as mudjacking or sandjacking. PolyTech is the Twin Cities’ leading geotechnical contractor for residential, commercial, industrial and municipal projects. Services include polyurethane concrete raising, soil stabilization solutions, void fill grouting, concrete culvert repair, concrete crack repair, interior floor leveling and bridge repair and maintenance solutions. Concrete raising applications include sidewalks, steps, stoops, concrete patios, driveways, garage aprons, garage floors, shop floors, pool decks, basement floors, slab on grade structures, loading docks, warehouse floors, bridge approaches and more. We can eliminate trip hazards, correct drainage along your foundation and stabilize weak soils. Our process is clean, reliable, and requires little down time. PolyTech offers additional applications for warehouse floors that become unstable due to heavy machinery and forklift use. These applications include concrete joint support, machine pad support, void filling, slab raising and floor stabilization.
