Compaction Grouting uses low mobility grout to rapidly improve discrete zones of weak or loose soils. The method provides a low cost, low risk solution for underpinning, liquefaction mitigation and re-leveling of buildings back to their original elevation. It can be used on large projects using high capacity plant as well as with hand tools, allowing improvement to be carried out in the most restricted locations.
The ground can be improved by adapting certain ground improvement techniques. Vibro-compaction increases the density of the soil by using powerful depth vibrators. Vacuum consolidation is used for improving soft soils by using a vacuum pump.
