When the retained soil cannot be de-watered, a sheet pile earth retention system is an effective solution. Sheet piles are steel sections in a wide variety of cross-sectional shapes - all with the ability to interlock with one another forming a continuous, watertight wall. The sheets are driven or vibrated into the ground. Cantilever walls are typical, but the sheet piles can be laterally braced to suit the specific needs of the work site. Being manufactured from steel, they offer a high strength material with excellent quality control.
