Foam Jacking and Concrete Lifting in Houston, Texas

Foam jacking is a concrete lifting method that raises sunken or uneven slabs by injecting expanding polyurethane foam through small holes in the concrete. The foam fills the empty spaces underneath, lifts the slab back to level, and hardens into a lightweight, waterproof base. Two Brothers Foundation Repair provides foam jacking for driveways, patios, sidewalks, porches, garage floors, and commercial slabs across the Greater Houston area.

Sunken concrete is more than an eyesore. It creates trip hazards, traps water, and can tilt rain back toward your home's foundation. Replacing the slab means demolition, new concrete, and days of curing. Foam jacking lifts the concrete you already have, usually in a few hours, with very little mess and at a fraction of the cost of replacement.

Why Concrete Sinks in Houston

Concrete sinks when the soil underneath it shrinks, compresses, or washes away, leaving empty spaces called voids. With nothing supporting it, the slab drops into the gap and cracks.

Houston is especially prone to this because most of the area sits on expansive clay soil. The clay swells after heavy rain and shrinks during dry, hot stretches. Each cycle loosens the soil under driveways, patios, and walkways. Poor drainage, downspouts that empty next to the slab, and soil that was never properly compacted before the concrete was poured all speed up the process.

How Foam Jacking Works

1. Inspect and measure. We find where the slab has dropped, how far it has moved, and what caused the soil under it to fail.
2. Drill small injection holes. We drill a few holes about the size of a dime through the sunken section of concrete.
3. Inject the foam. High-density polyurethane foam is pumped beneath the slab, where it expands to fill the voids.
4. Lift to level. As the foam expands, it raises the slab. We control the injection carefully and monitor the lift until the concrete is back in position.
5. Patch and clean up. We seal the injection holes and clean the work area. The foam cures quickly, so most surfaces are ready to use the same day.

Foam Jacking vs. Mudjacking vs. Replacement

Foam jacking and mudjacking both lift existing concrete instead of replacing it. The main difference is the material. Mudjacking pumps a heavy cement slurry under the slab, while foam jacking uses lightweight polyurethane foam.

Because foam adds very little weight, it is a strong choice for Houston clay, where heavy fill can cause the soil to compress and settle again.
