\  The main function of the diaphragm wall is to give lateral support to excavations by offering a reaction to horizontal forces from earth and water pressures.

\  Diaphragm walls are a safe and cost-effective solution for retaining the vertical faces of excavations. They are ideally suited to sites that are close to existing roads or buildings and can be used in conjunction with props and ground anchors.

\  Constructed on a panel-by-panel basis formed in the ground, diaphragm walls restrict the effect of ground movement caused by excavation work. The load deformation of reinforced concrete diaphragm walls is very small and there is virtually no limit to the scale of excavation that can be supported.
