Fracture / claquage grouting is the intentional fracturing of the ground by high-pressure injection of cement-based grout through sleeve port pipes to form intertwined lenses or veins of grout in order to provide reinforcement and even some consolidation of the soil. Grouting is typically performed in several phases, with repeat injections at each port to ensure the formation of multiple fractures through the soil.

When performed concurrently with underground construction such as soft ground tunneling, fracture grouting of the soils between the tunnel and overlying structures has the specific design intent of providing a controlled ground heave to compensate for potential structural settlement. Such an application of fracture grouting is referred to as compensation grouting
