Polyurethane Foam Injection also known as Foam Injection is a process of injection a 2 part polymer underneath concrete to fill voids, re-compact soils, and even achieve lift. This process has a wide variety of uses and applications. If you are noticing concrete sinking or breaking, you may need foam injection. Concrete is heavy and anytime there is poor drainage or poor compacted soils the weight of the concrete will sink into the ground. This creates trip hazards and eventually causes the concrete to break apart over time. Sure you could replace the concrete and if the situation is bad enough you should. But, if you having slight settlement, spending several thousands of dollars just to have it level seems a little much. No worries, Polyurethane to the rescue! Polyurethane is a two part chemical that is comprised of a resin and an iso. One component creates the expansion and the other hardens. Together we have a structural foam solution to lift and stabilize concrete slabs of all kinds. Before Polyurethane there was a process called mud-jacking. The reason it was replaced with Poly was because the mudjacking process was less effective and ultimately a temporary solution. The cementitious grout mix used in mud-jacking can get eroded with water. If that can happen, what's the point in using it in a poor drainage situation that created the problem in the first place. Polyurethane is hydrophobic and actually repels water. Also the light weight composition allows it to fill voids and sit on sub-standard soils; whereas the heavy weight of mud-jacking grout just sinks into the failed soils. Another benefit of the Poly is the expansion. This allows us to re-compact the underneath soils in addition to filling lateral voids. All in all the Foam wins in just about any aspect of the process.
