King Sheet Piling (KSP®)

The award-winning King Sheet Piling (KSP®) retaining wall system typically saves 35% to 40% of the steel used in a standard wall, whilst delivering marked productivity, environmental and sustainability benefits. It can be up to 4 times faster to install.

What Does KSP Offer?

KSP is a simple, radical innovation that revolutionises 120 years of sheet piling practice. It uses sheet piles more efficiently to yield typical steel savings of 35% to 40% in standard cantilever walls, whilst guaranteeing dramatic productivity, environmental and sustainability benefits.

How Does KSP Work?

Many sheet pile walls are sized for driveability, using heavier sections than required structurally for the wall. KSP harnesses the surplus structural capacity by 'thinking laterally' to use pairs of Z section piles as "kings" with lighter, shorter Z piles or "intermediates" spanning horizontally between them. For further details, including options for water cut-offs, see the Technical page.

What is KSP’s Track Record?

To date KSP has delivered:

  • Multi-million pound savings for Contractor and Client
  • De-risked critical programmes on two major projects worth a combined £1.2 billion
  • Substantial sustainability, constructability and environmental benefits
After 25 km of KSP on the M25 motorway DBFO initial widening, KSP has since been used on over 18 schemes across the Highways England network. KSP walls are now the solution of choice where sheet pile walls are considered and are a familiar sight across the nation’s roads. KSP walls have also yielded substantial savings on Network Rail projects.
