Sheet piling is a process where thin interlocking steel sheets are used to construct a continuous barrier in the ground. They can be used for various purposes and be of permanent or temporary nature.
In most cases, sheet piled walls are used as a temporary shoring method, which allows excavation either in or beside a sheet piled area, to allow personnel and equipment safely into an area that would otherwise not be achievable.
Sheet piling can also be used as a barrier to fill up against, for temporary roads and pads etc.
Sheet piled retaining walls are often reinforced by use of internal propping, bracing, anchors or whalers. It is possible to remove and reuse sheet piles making this an economically attractive retaining wall system.
