Most Polyurethane Foam Concrete Lifting, Stabilization and Void Filling projects can be completed quickly and economically with minimal disruption, and one day turnaround and return to service. 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 completed, the hole is patched with polymer concrete or cement. The concrete slab is repaired and for immediate use. The concrete repair typically takes a 1-2 hours based on the scope of your project. Most jobs can be done in one day. Polyurethane concrete raising achieves the same results as traditional mudjacking, but with a lightweight 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 concrete raising is a cost-effective alternative to replacing concrete. Concrete raising can usually be done for less than half the cost of pouring new concrete. However, the savings may be even greater, since when concrete raising the costs of demolition, removal, and landscaping are eliminated. Polyurethane foam concrete lifting and stabilization avoid costly tear out and disruptive replacement of the slab. This allows the surrounding area to remain in use or service even during the project with minimal downtime, if any.
Polyurethane typically cures in minutes after injection allowing areas to be fully available in minutes not days.
ProRise geotechnical polyurethane foams are ideal choices for making repairs to sunken or misaligned concrete slab sections around residences and structures.
