Raising by injecting polyurethane is used to raise and support sunken concrete. Holes are drilled and material is pumped under the sunken concrete. Foam is significantly lighter and cures faster than slurry mud mixes. This means you’re not adding more weight to an area that was susceptible.
Once the foam sets (which is typically less than 60 minutes) water cannot penetrate it. It simply bounces off.
This means the foam won’t go away and will provide a long term stable footing for the slab. It doesn’t mean you still don’t need to correct the water issue as ongoing water can still wash away the footings the foam is sitting on, but it won’t go away.
Our material has an impressive lifespan for it is not affected by water, does not change its shape or form, and will not break down over time as other materials often do.
