Polyurethane Foam Void Filling

Pumped at full volume fillfoam does not lose volume when pumped in confinement.

Polyurethane foam void filling.

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. The foam expands approximately 3 times its original volume is tack free in approximately. Fill and seal expanding foam sealant is urethane foam designed to fill large areas quickly and permanently.

High density polyurethane foam injection is used for concrete lifting concrete stabilization and void filling under concrete. It can be cut after 5 minutes and reaches full strength in an hour. Without the bi product of heat fillfoam is a safe and fast way to fill voids and cavities quickly and with limited access. The key to uretek s void fill process is our patented geopolymer and unique polyurethane injection methods.

Concrete slabs settle due to voids or unstable soil. Fillfoam is a pre expanded open cell foam formulated with ideal characteristics for any void filling applications. By utilizing soil reports and the customer s property knowledge uretek provides an accurate void fill solution tailored to your specific needs. By pumping polyurethane foam through the concrete you essentially push the concrete slab back up from below.

Lifting concrete with foam offers the same results as traditional concrete mudjacking for raising stabilization and void filling but with new and improved characteristics. Of the most resilient void fill foams ap fill 420 is a two component high expansion hydro insensitive polyurethane foam. Mudjacking and polyurethane injection work to fill the voids in the soil under the structure and help halt the unfolding catastrophe. Void filling properties of polyfoam vs.

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. Ap fill 420 weighs 1 8 to 2 2 pounds per cubic foot. Patch up the holes with concrete and your new driveway or sidewalk or walkway will look good as new. The foam will fill up the parts of the concrete that are uneven and will raise it to the proper height.

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. 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.
