Polyurethane Foam Slab Jacking

Polyurethane foam slab jacking offers a newer, less labor-intensive alternative for raising sunken concrete slabs and walkways replacing the cement-based grout mixture typically used for slab jacking with a two-part polyurethane that reacts and expands with enough force to fill voids and raise concrete.

One of the key benefits of using polyurethane is that it’s pre-formulated with the exact characteristics needed for specific jobs as well as saving installation time by using more efficient resources. Instead of hauling tons of material with heavy equipment, the polyurethane process is less labor-intensive to transport and work with and can be less evasive for our customers.

The two liquid components that mix to create the polyurethane foam are kept separate in drums or totes until they are mixed at the tip of the injection gun. When the two liquids combine and react, the foam expands 20 to 25 times its volume within seconds reaching material set in as little as fifteen minutes.

Backyard Patio Concrete Raising

Team Atlas was called to raise this back patio that had settled approximately 2 inches.

Success! Back Patio raised back to original position.

Front Porch Concrete Raising
The customer wanted to raise the concrete walkway up to prevent standing water at the front steps. Success again – Front Patio raised 2 1/2″ then we overlaid a row of brick on top of the existing step to make step level with the newly raised walkway.

2. The Right Team

3. The Right Process
Drill a 1/4″ hole in the concrete and install a white injection port making the area ready to pump the poly foam under the sunken concrete…
