The Polyurethane Concrete Raising Process

Small, precise holes are drilled into the concrete slab at carefully chosen spots to reach the problem areas beneath. Then a high‑strength, expanding foam is injected under the slab through those openings. As the foam’s components blend, they create a powerful chemical reaction that causes the material to rapidly expand.

This expanding foam rushes into empty spaces, fills hidden voids, and gently lifts the sunken concrete, restoring smooth joints, safe walkways, and proper drainage. The material is lightweight, incredibly durable, and permanent, weighing only about 2 pounds per cubic foot — yet strong enough to support heavy loads for decades.

Most concrete lifting projects take only a few short hours from start to finish, and your concrete is ready to use immediately once the job is done. No waiting. No mess. No downtime.
