King Post Walls

King post retaining walls are a fast and cost-effective way of building permanent or temporary retaining walls, which are occasionally referred to as soldier piles.

They are formed by installing steel H-beams, Universal Columns (UC’s), or sometimes universal channel sections into rotary bored, CFA or SFA piles and can be used with and without anchors.

Concrete precast, prestressed or timber panels are subsequently installed between them to allow for earth retention.

What are king post walls used for?

King post retaining walls are suitable for most earth retaining structures, typically used for basements, the retention of embankments and slopes and for flood defence walls. Suitable for both permanent and temporary retention conditions.

  • Cost effective system for use in hard ground
  • Versatile retention system easily adapted to variable rock levels and changes on site
  • Can be used in combination with ground anchors
  • Seamless transition for follow on construction activity
  • Locally sourced and recycled materials can be used as infill panels
  • Precast panels can include architectural features
  • Cost-effective alternative to sheet piling or contiguous, secant or sheet piled walls due to reduced pile numbers
  • Suitable for permanent and temporary retention
  • Can be used with or without anchors
