Sheet piling

Coffer Dams, Temporary or Permanent Retaining Walls

Sheet piling

Sheet piling is an earth retention and excavation support technique that retains soil, using steel sheet sections with interlocking edges.

Sheet piles are installed in sequence to design depth along the planned excavation perimeter or seawall alignment. The interlocked sheet piles form a wall for permanent or temporary lateral earth support with reduced groundwater inflow. Anchors can be included to provide additional lateral support if required.

Sheet pile walls can be used to retain water from pump shafts, support excavations for basements, carparks, tunnel launch pits and many other types of deep excavation. Sheetpiles can also be used to create seawalls and bulkheads. Permanent steel sheet piles are designed to provide a long service life.

Vibratory hammers are used to install sheet piles. If soils are too hard or dense, an impact hammer can be used to complete the installation.

Sheet piles can also be used as a permenant retaiining wall for harbours or bridge abutments, Sheetpiles can be coated to increase there lifespan when being used in water or agressive soil types.
