Polyurethane grouting is the cleanest concrete lifting and stabilization process. The injection equipment is mechanically connected to the slab or structure. Mechanical seals engage when not injecting material, no loose material is introduced to the repair area. Extruded material is easy to clean up because it cures very quickly.

Polyurethane grouting is the quietest and fastest process for stabilizing and raising settled concrete slabs. Because of the small hole size, drilling is fast and quiet. There is virtually no noise associated with the injection process itself. The equipment for polyurethane grouting is self-contained in a box truck. The trucks can park up to 400 feet away from the injection point.

Polyurethane grouting crews can lift up to 12 times faster than standard slab jacking or mud jacking crews in many situations. Because of the small hole size and ability to lift larger areas per hole, polyurethane grouting is much quicker than slab jacking. Because of the equipment design, upon arriving on a job, polyurethane grouting crews are typically actively lifting slabs within 10 minutes of arrival for typical repairs.

Lightweight material reduces the overburden on underlying soils, reducing the chances for resettlement. Even the highest density polyurethane foams used for polyurethane grouting are significantly lighter than alternative lifting and stabilization materials. This reduces the amount of additional burden weight placed on the underlying soils. Geotechnical polyurethanes are an excellent choice for lightweight fills. Because of their exceptionally low unit weights (down to 2 PCF) and fast cure times (few minutes).
