CUTTER SOIL MIXING
CSM is an advanced soil mixing technique utilizing two rotating cutter heads to form a homogenous soil mix retaining wall that can also serve as the final structural perimeter wall and a water cutoff structure. This can result in cost and schedule savings during excavation, dewatering, and perimeter wall construction.
WALL AND FOUNDATION INSTALLATION
Cutter Soil Mixing (CSM) panels are formed by drilling overlapping primary and secondary panels to depths up to below grade to serve as a soil retaining and water cutoff wall. Two soldier beams are precisely placed in each panel with survey control and templates to maintain proper placement and verticality. Bentonite slurry is used during drilling and replaced with cement slurry during extraction to provide a structurally sound, low permeability wall.
CSM RETAINING WALLS
- seals groundwater flow
- improves excavation schedule
A CSM wall minimizes the need for temporary and permanent dewatering and the risk of dewatering underneath adjacent structures and roads that could cause settlements outside of project boundaries.
