"WebProcess. Chemical grouting transforms granular soils into sandstone-like masses by filling the voids with low viscosity, non-particulate grout. Sands with low fines content are best suited for this technique. Typically, a sleeve port pipe is first grouted into a pre-drilled hole. The chemical grout is injected under pressure through the ports. " - Rock grouting
