What Is Pressure Grouting?
Pressure grouting is a geotechnical process involving the high-pressure injection of specialized grout materials—such as cementitious, chemical, or polyurethane grouts—into voids, soil, and fractured ground beneath slabs or structures. This technique strengthens soils, fills cavities, and provides essential support for concrete slabs, foundations, utilities, and other critical systems.
Often used interchangeably with slabjacking or mudjacking when applied under slabs, pressure grouting fills both voids and soil gaps, ensuring improved load-bearing capacity and reduced settlement.
Engineered Subsurface Support
Pressure grouting repairs subsurface voids, stabilizes weak soils, and can lift or support settled concrete without requiring full slab removal — saving time and cost while maintaining structural integrity.
