Ground Improvement
Crux has been providing ground improvement services to the geotechnical industry for more than 10 years. Our lightweight, componentized drill equipment allows us to access the most environmentally sensitive and difficult-access sites above-ground, as well as to work within the most tightly confined tunnel spaces below the surface.
DewateringWe provide dewatering services to improve ground stability. Slotted PVC screen and riser is inserted into drilled shafts, creating a conduit to allow water to be pumped out or drained. Through various successful projects, we have gained extensive experience in angle- and horizontal-drilled dewatering techniques. GroutingWe offer grouting services to stabilize terrain, preventing cave-ins and obstructing groundwater from infiltrating excavation. Permeation grouting is used in cases involving fine fractures to stabilize groundwater and flow through the rock mass. Low viscosity grout is injected into the rock or soil to decrease permeability and increase the solidity of granular soils through the hardening of the grout. Tube Arch CanopiesCrux has extensive experience in spile installation used to improve tunnel-enveloping ground conditions. Cased horizontal holes with one-way grout valves are drilled to desired depths in an arch formation above the tunnel alignment. Pressurized grouting is then performed to complete the stabilization process, decreasing the risk for possible cave-ins. Peripheral FreezingCrux provides cased horizontal boreholes to support peripheral freezing prior to tunnel excavation. Peripheral freezing involves installing closed-loop freeze lines to temporarily freeze the ground surrounding tunnel alignments and create more stable drilling conditions. |
