Polyurethane foam is used in a number of different applications. Polyurethanes are a strong material that is often used to manufacture high-resilience foam seating, rigid foam insulation panels, and durable elastomeric wheels for roller coasters, for elevators. Repairing concrete slabs is simplified with high-density polyurethane foam that is injected beneath the slab of concrete to raise it up, and keep it level with the area around it. High-density polyurethane is very popular marketplace-driven product because of the low cost and quick repair it offers. There is not a lot of equipment or machinery that is required for pumping polyurethane. Just a pumping system and the container that holds to foam is needed for the installation. Crew members pull the hose to the area being repaired and inject polyurethane foam under the slab through a series of holes drilled into the concrete, filling voids and raising it to the proper level. Polyurethane concrete raising much quicker than other repair methods, and will only take about a few hours till your concrete is fully repaired. Polyurethane has high durability and provides a solid and dense product that can permanently support the roadway structure. Therefore, it will provide a sturdy foundation allowing you to not worry about walking or driving over the repaired concrete slab.
However, consumers must remain cautious about HVAC ducts that may run through the floor since the foam could infiltrate and clog them. It’s also necessary to perform plumbing tests prior to the foam injection to ensure there are no leaks in the supply or drain lines. So having a professional do the job will be very important to make sure the problem is fixed, and that no additional problems are created.
