Compaction Grouting
A ground improvement method that uses stiff, low-mobility cement grout injected under controlled pressure to compact and densify weak soils. As grout is placed, it displaces surrounding ground and builds dense, bulb-shaped masses that increase stiffness, improve bearing capacity, and help limit settlement.
Common applications include:
- Treating sinkholes, voids, and washouts
- Improving support beneath existing foundations
- Reducing liquefaction susceptibility in loose soils
- Managing settlement risk for new construction
