It involves the Injection of grout material into the underlying rock mass. The major goal is to reinforce and reduce the formation’s permeability. The techniques involved drilling grout injection holes into rock to prevent fissures or cavities from forming. After that, the grout is pumped under pressure.
The consolidation grouting process minimizes permeability and deformability by enhancing strength against sheer pressures. Consolidation grouting reduces water flow outward in high-pressure water shafts and tunnels.
Consolidation grouting is based on geotechnical data, specifications including the pattern of hole layout, technical requirements, and so on for enhancing the water-tightness of shallow foundations created in a small region.
