Diaphragm walls are subsurface reinforced concrete structures formed and cast in slurry trenches.
✔ Diaphragm walls are subsurface reinforced concrete structures formed and cast in slurry trenches. Excavation is accomplished by digging panels along temporary guide walls using a mechanical or hydraulic clam shell attached to a rig or crane, and then connecting the panels to form continuous walls.
✔ Bentonite or polymer based slurries are used during construction to prevent soil incursions into the trenches. Reinforced cages are placed followed by structural concrete.
✔ The result is a structural wall system that not only provides temporary earth support and a groundwater barrier, but also provides the permanent foundation system, being load-bearing.
