Compaction Grouting

Compaction Grouting is the stabilization of poor soils under buildings, structures, roadbeds, railroads, or runways, by driving injection pipes down to stable ground and then injecting low-mobility grout to force out soft soils and replace with grout columns. Injeciton is continued in a pattern to cover all of the target area until the ground or building is raised back to original elevation. The amount of grout injected and pressures at each lift are closely monitored for quality control.
