Polyurethane Foam Void Filling

Of the most resilient void fill foams ap fill 420 is a two component high expansion hydro insensitive polyurethane foam.

Polyurethane foam void filling.

Lifting concrete with foam offers the same results as traditional concrete mudjacking for raising stabilization and void filling but with new and improved characteristics. For similar products see the page on concrete leveling. It can be cut after 5 minutes and reaches full strength in an hour. Uses include filling holes cracks or gaps that require a complete airtight and waterproof seal but are too large to be filled with ordinary caulk.

The key to uretek s void fill process is our patented geopolymer and unique polyurethane injection methods. Pumped at full volume fillfoam does not lose volume when pumped in confinement. By pumping polyurethane foam through the concrete you essentially push the concrete slab back up from below. After the geolift has done its magical work the last thing left to do is patching up the holes.

Void filling spray foam insulation cover large areas with this two part expanding foam insulation. First small holes are drilled through the area to be filled then the foam is injected under the slab filling the void and lifting the slab back to a level position. Mudjacking lifts the concrete foundation up on a densely packed swelling wave of slurry a mixture of hard fill including mud sand cement crushed limestone etc while polyurethane injection utilizes dense. High density polyurethane foam injection is used for concrete lifting concrete stabilization and void filling under concrete.

The foam will fill up the parts of the concrete that are uneven and will raise it to the proper height. In our experience using both traditional mudjacking and polyfoam for concrete leveling we have determined that the void filling properties of these foam products are more unpredictable than traditional mudjacking and not worth our customers time or money. Fillfoam is a pre expanded open cell foam formulated with ideal characteristics for any void filling applications. It s the top slab solution for polyurethane void fill.

By utilizing soil reports and the customer s property knowledge uretek provides an accurate void fill solution tailored to your specific needs. Ap fill 420 weighs 1 8 to 2 2 pounds per cubic foot. The foam expands approximately 3 times its original volume is tack free in approximately. Concrete slabs settle due to voids or unstable soil.
