Sheet pile wall cappings

Permanent sheet pile wall structures are finished off at the top with a steel capping or reinforced concrete capping beam.

They are designed to suit constructional and operational criteria. However, structural considerations also play a role if the capping is required to transfer support reactions (capping beam). With adequate bending stiffness, a capping enables the top of the wall to be aligned, distributes operational loads and prevents uneven deflection of the top of the wall.
