Polyurethane (poly) concrete leveling involves using a polyurethane foam material to raise and level sunken or uneven concrete slabs. The polyurethane foam is injected beneath the concrete slab through small holes drilled into the surface. The foam expands and fills the voids underneath the concrete, raising it to the desired height and level.
Poly concrete leveling has several advantages over traditional mudjacking, including:
Lightweight: The polyurethane foam used in the process is much lighter than the mixture of cement, soil, sand, and water used in mudjacking, reducing the stress on the existing structure.
Faster: The injection process is quicker and less labor-intensive than traditional mudjacking, making it a more efficient solution.
Stronger: Polyurethane foam is more durable and long-lasting than the mixture used in mudjacking, providing a more stable and permanent solution to sunken concrete.
Better Insulation: The foam used in poly concrete leveling provides insulation properties, making it a better solution for outdoor surfaces that are exposed to the elements.
It's important to note that poly concrete leveling is not a one-size-fits-all solution and may not be suitable for all concrete leveling projects. A professional contractor, like Keystone Basement Systems, should assess the specific needs of each project and recommend the best solution.
