poly foam injection bauDo you have a patio, driveway, or other kind of concrete slab that is starting to sink or settle? Erosion, dry conditions, and poor construction can cause concrete slabs or floors to settle and even crack. When this happens, the concrete not only looks unsightly, but can also become a tripping hazard. That is why you should invest in concrete lifting from Bay Area as soon as possible. But what is the right method for your concrete lifting needs? One excellent method is our polyurethane foam injection.

Polyurethane foam injection is designed to lift/level concrete and fill in voids without replacing existing concrete. Whereas it will take multiple days to prep, pour, and finish a new concrete slab, poly injection can be done the same day with minimal cleanup and the area may be utilized after repair.

How Poly Foam Injection Works

Poly foam is a two part urethane chemical that expands into a foam consistency when mixed. After the two parts mix the foam forms and starts to expands which creates the ability to fill voids and lift slabs.

In order to inject the polyurethane foam under the concrete slab a 5/8 inch hole would be drilled through the concrete. An injection port is hammered in the hole for a solid seal to prevent back flow. Here is when the magic happens! The poly foam is injected in the port, through the hole and underneath the concrete slab.

Polyurethane is a minimally invasive, quick process that can be used in a variety of different situations for concrete leveling. Whether the sinking slab is a floor or patio, polyurethane foam injection can help. Just what we can raise with polyurethane foam?
