J N Piling are able to offer the design (where required), supply and installation of steel sheet piles (Z or U piles) to form both permanent and temporary cofferdams using the methods covered in the What We Do section.

Steel sheet pile cofferdams can retain both ground and water to allow the enclosed area to be pumped out and excavated dry.

Sheet pile interlocks are able to be sealed or welded if required to improve water tightness.

Sheet pile cofferdams can be modified with the use of walings, tie bars or ground anchors.
