Sheet Pile > Union Straight Web Sections

Union straight web sheet piles are designed for the construction of cellular cofferdams which can be used when considerable depths of water, or subsequently placed fill are to be retained. They are also used when it is not possible to drive far into the ground, necessitating a free-standing gravity structure.

Typical uses of straight web piles are construction of permanent walls for land reclamation, quays, wharfs and dolphins. They can also be used for structures to temporarily seal off dock entrances so that low level work can be carried out in the dry.
