How it Works

• Chemical grout is injected as liquid polyurethane solution under much less pressure than compaction grouting.
• The polyurethane grout chemically reacts over time to form a mass that fills and supports the designated area.

Chemical grouting in most commonly used to stabilize loose soil areas near the surface. Geotechnical contractors and drillers also use this process to solidify soft soils to allow soil borings or excavations. Chemical Grouting is often used in situations where high pressure compaction grouting would be too ricky for nearby structures.

Uses of Chemical Grouting

• Stabilize loose soil areas near the surface
• Creating water-impermeable barriers
• Solidify loose soils to allow soil borings or excavations

Advantages of Chemical Grouting

• Much less pressure required than compaction grouting.
• Able to penetrate voids, fissures, pores and soil conditions that are too small for typical cement grout penetrations.
