During basement excavation or tunnel crossing, high groundwater and permeable soils can cause water inflow and collapse. Water injection grouting requires fast mobilization, technical skill, and calm on-site response.
Large water inflow and collapse risks often appear in basement excavation, dewatering well sealing, and tunnel excavation. Each site requires quick judgment of groundwater level, soil permeability, and site risk before grouting and consolidation.
Water inflow can occur when diaphragm walls break, pile gaps are too large, groundwater is high, or soils are highly permeable. If gravel or sand falls onto wall construction joints, rising water pressure may also force water into the basement.
