Permeation grouting is typically defined as the injection of a low-viscosity grout (sodium silicate, microfine cement, acrylate or polyurethane) into the pores of the soil without displacing or changing the soil structure to impart strength and/or reduce permeability. The characteristics of the ground are modified with the hardening or gelling of the grout. Depending on the requirements of the project, grout materials can be temporary or permanent.
