Polyurethane foam has for many years been used to lift and level concrete sections such as sidewalks, patios, driveways, garage floors, warehouse floors, and other uneven or sunken concrete that could pose problems such as trip hazards, water ponding, or expensive total tear out and concrete replacement.
Unlike traditional repair methods such as heavy cement based "mudjacking," polyurethane is lightweight and will not add any extreme weight to already loose or poorly compacted soils. Additional Advantages include:
- The polyurethane is injected through a 5/8 inch hole in comparison to much larger 1-1/2 to 2 inch mudjacking injection pumping holes
- Clean application for interior and exterior application
- Numerous polyurethane systems are available to meet the various soil, slab sub-grade conditions and load applications
- Injected as a liquid, the polyurethane will flow uniformly into voids and sub-grade cracks and fissures
- The use of polyurethane polyjacking can eliminate the possible need to tear out and replace expensive slab section
- Once the slab is raised back to its original grade or position, the slab section can be put back into use
