Compaction Grouting is the process of injecting a stiff, mortar-like grout under varying pressures and flow rates, to ensure a homogeneous expanding mass of grout in pre-specified zones of soil. The surrounding soils from the injection point become densified as the existing soil pour space is reduced by the expanding mass of grout. The use of controlled flow rates and grout pressures, with proper casing installation and extraction rates, enable the grouting to be performed under water or to form pile shaped structural elements which immediately improve the soil’s characteristics in the area of injection.
Low Mobility Grouting (LMG)
Low Mobility Grout is typically used where the soils are less compactable than that for compaction grouting, and where displacement is the key element for LMG. This application is more commonly used for void filling, displacement of soft soil, solidification of fractured rock, filling voids in rock fill, and foundation lifting over large areas.
