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:
2020 saw completion of substantial anchored and cantilever KSP walls for Langport Embankment for Network Rail, following on from those on Bridgewater rail embankment in 2019. KSP walls completed or in progress for Highways England include M23 J8-10, M1 J13-16, M4 J3-12, M25 EAs 01 & 06 and A19 Norton to Wynyard. Further KSP walls are envisaged on Highways England SMA schemes currently in the design phase.
