Caisson walls are typically used in areas with poor or wet ground conditions. Caisson walls are designed where it is otherwise not possible to install lagged shoring without suffering the loss of ground, such as excavations that penetrate below the water table. Caisson wall shoring is also utilized where excavation support is required in close proximity to existing structures or services. This structural support system helps to reduce any movement to neighbouring structures.
A caisson wall is completed by drilling vertical holes which are interlocked. This system is a more rigid system than traditional soldier piles or lagged shoring. Similar to a lagged shoring system, caisson walls can be braced by tiebacks, rakers or struts.
