Diaphragm Walls are cast-in-situ walls used as retaining walls for perimeter walls of deep, multi-level basements and underground parking facilities, highway cuts, subways, underpasses and shaft walls. T-Shaped diaphragm wall is used for deep-water wharves.
FS has, by use of cast-in-place diaphragm walls, built steel mill pits, steel rolling mill pits, marginal wharves, docks, deep basements for buildings, underground parking, retaining walls, bridge abutments, dams’ foundations, cofferdams, walls for underground water reservoirs, canal training walls, underground drainage and sewage covered canals, walls, seawalls, dry docks.
Diaphragm walls are ideal for the construction of wharves using the FS 'T-shape' panels, also for slurry walls made of self-hardening mud used for isolating and cutting off the water table. This can also apply to isolation of dumping areas, sewage disposal and industrial effluents where it is necessary to avoid pollution of underground water.
FS diaphragm walls can also be used in rock excavation for dam foundations.
