At Burnside we, specialise in Cofferdams temporary work applications.
Cofferdams are simply an extension of the principle of a sheet pile retaining walls, as the soil has to be retained. This would be used to construct a reinforced concrete sub structure or the installations of underground tanks. This allows the added structural integrity benefit to be gained by propping opposite walls off each other using sheet piles and support frames. This offers a reduction in the embedded depths required allowing deeper excavations to be supported.
