Diaphragm (slurry) walls - DeepEx

Slurry wall construction cost for cut-off barries is considerably cheeper than diaphragm wall construction for deep excavations. The differences arise mainly from construction method differences. In cut-off walls construction is much quicker as a continuous trench is excavated and backfilled and reinforcement cages are seldomly used.

Diaphragm wall - Franki Foundations UK

A diaphragm wall (slurry wall) is a reinforced cast-in-place continuous concrete wall. The construction includes the excavation of a trench under the protection of a support suspension (i.e. a thixotropic slurry such as bentonite mud for example) designed to temporarily stabilize the trench wall. After excavation with a mechanical or hydraulic
