Unlike traditional invasive concrete repair methods such as mudjacking and concrete replacement, polyurethane foam injection utilizes high-density polymers to stabilize and lift concrete. It also much lighter material that requires smaller and fewer injection holes. Also known as foam lifting, polyurethane concrete raising is the latest and greatest concrete repair method available.
Polyurethane foam injection is both lightweight and durable and is able to support and lift sunken concrete without any extra added weight. It also provides an affordable and less invasive solution to your sunken, cracked, uneven concrete issues.
Most Polyurethane Foam Concrete Lifting and repair projects can be completed quickly and affordably with minimal disruption, and one day turnaround and return to service. The concrete repair typically takes a 1-2 hours based on the scope of your project. Injection holes are strategically drilled into the concrete slab(s) that requires lifting.
The equipment is contained in a trailer rig with a long hose capable of reaching direct to the concrete slab location. Polyurethane foam is then injected under the slab filling voids, and raising it to the correct level. After the injection is done, the hole is patched with polymer concrete or cement. The concrete slab is repaired and for immediate use.
