All the retaining structures processes

Diaphragm walls: Concrete panels to stabilize trenches during excavation

A diaphragm wall is a panel of reinforced concrete poured in the ground. The stability of the trench during boring operations, installing the rebar reinforcement, and concreting is obtained by using a drilling fluid called slurry, which is made using bentonite.

The reinforced concrete cut-off wall can be temporary or permanent, in which case it becomes part of the final structure. Due to its great inertia, a diaphragm wall is very resistant to deformation.

Besides their retaining function, diaphragm walls can act as foundations and provide waterproofing.
