Polyurethane Foam Injection Concrete Lifting

Foam injection offers the same great results as our grout based method.

Polyurethane foam injection concrete lifting.

Polyurethane concrete lifting uses a high density foam material that is injected under the slab. When the components of this material are mixed a reaction causes the material to expand. Polyurethane foam is injected into the holes causing a chemical reaction to fill uneven space under the slab. Lifting concrete with foam offers the same results as traditional concrete mudjacking for raising stabilization and void filling but with new and improved characteristics.

Lifting foam will fully expand within 10 15 seconds allowing you to monitor the raising and preventing over raising the slab. The process starts with injection holes size of a dime strategically drilled to lift and restore sunken concrete. Foam injection offers a better longer lasting alternative to mudjacking or expensive replacement. How does polyurethane foam concrete raising work.

Polyurethane foam injection also referred to as foam jacking is the process of drilling holes into concrete and injecting them with polyurethane foam. What is polyurethane foam injection. Once everything is prepped and the hose and materials are in place the polyurethane foam is injected through the holes which fills the space underneath the concrete slab using the concrete slab itself to drive the foam into the crevices thereby lifting the concrete back to its original correct level. Also known as foam lifting polyurethane concrete raising is the latest and greatest concrete repair method available.

Raising concrete with polyurethane foam is done with incremental injections. With a range of installation methods and product performance characteristics our foam method may be the best and most cost effective. Polyurethane foam injection is an effective way to raise level or lift concrete in lieu of replacing the existing slab. We suggest using an air purged gun to deliver foam under the slab.

This expanded foam fills any voids beneath the slab and.
