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.
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.
To date KSP has delivered:
18 April 2018: February saw the start of KSP installation on the A14 Ellington to Fen Ditton highway project. Planned other UK Smart Motorway work this year using KSP walls includes the M1 Jnct 23A-25, M6 Jnct 2-4, M4, Jnct 3-12, M1, J13-16 and M23 Jnct 8-10. Last summer saw completion of KSP walls on M1 Jnct 19-16, M25 Jnct 30 Improvement and M5 Jnct 4A-6.
