Compaction Grouting

Compaction Grouting

Compaction grouting is injected into soil increasing its density. The grout pushes the ground to the side of where it was injected forming a bulbous grout column. The homogeneous and stiff grout mixture is pressurized at low injection rates just below the surface compacting and displacing weaker soils. Air and water are forced out of the soil mix in this process and injection can continue until containment pressure and heave are noticeable. Compaction grouting significantly hardens and stabilizes soil. Structures can be re-leveled, settlement mitigated and underground pipes and tunnels stabilized utilizing compaction grouting. Reduced dangers of liquefaction, bearing capacity enhancement and sinkhole prevention are just some of the benefits of using compaction grouting. Compaction grouting greatly improves soil conditions and can be more economical than using piling methods.
