Ruukki Pile Walls (RD Wall / O-Pile Wall)

Ruukki pile walls are formed by interlocking tubular steel piles to create a continuous retaining wall. The system provides bending strength, axial load capacity and a near-continuous seal against soil and water ingress. They are used for deep excavations, quay walls and flood defences where both retaining and vertical load capacity are required. They are particularly well suited when the retaining wall must be installed into rock.
