Diaphragm Wall

Building foundations of tomorrow

Diaphragm walls are generally reinforced concrete walls, constructed in the ground using an under-slurry technique developed in Europe. This technique involves excavating a narrow trench that is kept full of an engineered fluid of slurry. This way, walls with thickness ranging between 300 mm to 1200 mm can be formed as deep as 45 meters underneath. Inclined rock or soil anchors are used for this purpose.
Diaphragm walls are commonly used while constructing structures with deep basements in congested areas, as they can be installed in close proximity to the existing structures.
