How does Polyurethane foam concrete raising work?
Firstly, we believe it’s good for you to know that most concrete raising jobs will take between one to two (1-2) hours—start to finish—and your concrete will be ready for use immediately upon completion!
1. When you level your uneven concrete using poly foam concrete raising techniques, ⅝” injection holes are strategically drilled around the areas where the concrete is sunken and requires lifting.2. The concrete raising equipment is contained in a truck or trailer and has a sufficient length of hose to accommodate most locations, the hose is extended to reach the area in need of repair.3. Once everything is prepped and the hose and materials are in place, the polyurethane foam is injected through the holes which fill the space underneath the concrete slab, using the concrete slab itself to drive the foam into the crevices, thereby lifting the concrete back to its original, correct level.4. Upon completion of levelling the concrete, the injection hole(s) are filled discretely with new cement, allowing you to use your surface immediately.
