Concrete Lifting, Stabilization and Void Filling
Polyurethane 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 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.
On the day of your job, injection holes are strategically drilled into the concrete slab that requires lifting. The equipment is contained in a trailer, and has a sufficient length of hose to accommodate the location. Our equipment remains parked, while our crew pulls out enough hose to reach the area being repaired.
Polyurethane foam engineered specifically for concrete lifting is injected beneath the slab, filling voids, and raising it to the correct level.
The concrete lifting foam has an average reaction time of 12 seconds. Within those 12 seconds, the foam travels in a 6-foot diameter beneath your concrete, throughout the voids & then expands in a slow and controlled fashion.
Our lifting technician will “bunny hop” from hole to hole in order to lift your concrete slab to avoid breaking it. With use of our specialty equipment, this is extremely rare.
After the injections are complete, the holes are patched with a coloured hydraulic cement compound that is matched closest to the colour of your concrete.
At last, your concrete slab is ready for use immediately!
This repair typically takes a 1-2 hours based on the scope of your project.
