High Density Polyurethane Foam Injection

The polyurethane density is sufficient to completely fill cavities below a sinking foundation. Among the leading high density polyurethane foam products available ap lift 475 offers a powerful solution that is traffic ready in 15 minutes. When the components of this material are mixed a reaction causes the material to expand.

Polyurethane injection is a long lasting procedure.

High density polyurethane foam injection. High density polyurethane concrete leveling is the most efficient cost effective and environmentally friendly way to raise and stabilize existing concrete slabs. They become very rigid but are really easy to use and cure and can be used as a lightweight casting or filling material. Lightweight materials are used that will not cause additional soil compression and will flow easily during the injection process. High density polyurethane has a fast acting curing time which can help traffic control by reopening lanes immediately after the injection process.

This two component high strength high density hydro insensitive structural polyurethane foam supports 14 000 lbs per square foot. Polyurethane concrete lifting uses a high density foam material that is injected under the slab. This expanded foam fills any voids beneath the slab and lifts the concrete. This material will never lose density is permanent and is environmentally friendly.

Reducing the amount of delays and inconveniences can also be achieved by scheduling repairs during the night for quicker turn around. Used extensively by dots for over 3 decades polyurethane concrete leveling has been real world tested under the toughest conditions. Ap lift 475 weighs 4 5 to 5 0 pounds per cubic foot. Direct injection expanded foam molding is also known as injection molded foam and it s used to create soft foam products from a complex base resin made from an ethylene and polyolefin elastomer.
