This chapter details the ground improvement using grouting. Grouting can be defined as filling the voids in the ground for increasing shear strength, compressive strength as well as reduce the conductivity in an aquifer. Grouting are divided into hydro fracture grouting, permeation grouting, compaction grouting, and jet grouting. This chapter details the grouting process using cement and chemicals. Today, commercially available chemical grouts cover a wide range of materials, properties and costs, and give the grouter the opportunity to select a grout for specific job requirements. The decision on choosing a particular grout has been discussed. Chemical grouts namely Sodium Silicate System, Silicate Chloride Amide System and Silicate Aluminates–Amide System, Aminoplasts, Acrylamide, Epoxy Resins, N–Methylolacryl Amide (NMA), Polyurethane, Phenoplasts, Lignosulfonates, are dealt with. Case studies have been included at the end of the chapter.
