Repairing Foundations with

Polyurethane Foam Injections

Slab lifting & concrete repair using high-density polyurethane foam injection

High-density polyurethane foam injection offers a powerful solution for concrete slab repair. It is injected into concrete slabs to fill cracks and lift foundations. It solves issues like cracked concrete, filling voids beneath concrete, loose soil, and water seepage.

High-density polyurethane foam injection is a fast-acting solution, capable of lifting concrete slabs, filling abandoned pipes, and filling voids. It’s traffic-ready in just 15 minutes, offering high strength and efficiency. It works effectively in wet environments by displacing water and bonds with soil and concrete, making it suitable for a variety of applications, including pool surrounds, sidewalks, and driveways.
