For sites with minimal space or difficult access including railway embankments, cuttings, and suburban development projects. Also suitable for use in flood defence walls and traffic screening.


KingPost is a cost-effective retaining wall system also known as 'Berlin Walls' and 'Soldier Piles'. The system has a huge range of both structural and non-structural applications. The retaining wall structure is formed by the vertical insertion of H beams in the ground; pre-stressed concrete panels are mounted between them. The use of pre-stressed rather than precast concrete panels results in a high strength/ size ratio, ensuring that units can be lighter and thinner than precast alternatives.

The use of retaining wall systems on suburban development sites has increased as developers have tried to make maximum use of available space or design in underground structures.

There are however many other applications for this system, including in flood defence walls and traffic screening.

Features and benefits:

  • Easy to handle component parts, pre-stressed concrete panels and H beams.
  • Minimal risk of settlement and soil movement during installation process.
  • Minimal soil displacement, no arisings, which may incur muck-away cost.

General information





The panels have a smooth (ex-steel mould) finish. If special finishes or colours are required, including fair faced units or textured finishes, consult the manufacturer.
