Secant Pile Walls

Secant pile walls consist of reinforced and non-reinforced piles. The unreinforced piles are usually installed first and consist of cement or bentonite. The reinforced piles are then installed and the reinforcement can be either cages, I-beams or H-beams.

Secant pile walls retained by anchors or strutting system are often supported by a waler beam to distribute the loads (prevent punching of anchor/strut through the pile) and as a mitigation measure for the unlikely event of an anchor/strut not carrying the load. This waler beam can be constructed as a reinforced concrete beam casted towards the pile wall, or by using steel profiles to be fixed to the piles and anchors/strutting systems.
