What are the benefits of polyurethane foam?
Benefits of polyurethane foam to raise a concrete slab is a clean procedure. It does not create grout or concrete splatter and does not require any washing. The injection hole is 5/8 of an inch vs. 1 1/2" - 2" with traditional mudjacking, and when compared to mudjacking it requires a minimum amount of patchwork leaving a much cleaner, less noticeable result.
The results from raising a concrete slab using polyurethane are long-lasting. Polyurethane weighs approximately 4 pounds per cubic foot, while mudjacking weighs about 100 pounds per cubic foot.
The polyurethane foam we use are bio-friendly, consisting of 39-49 percent renewable and recycled materials.
