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:
8 June 2016: Up to 60% steel saved! 1.3 km of KSP walls on the A1 Coalhouse to MetroCentre Improvement achieved a new milestone, saving 44% steel on average, up to 60% steel on individual walls and 902 tonnes overall. The Arup design for Balfour Beatty included the first permanent works use of KSP walls with two pairs of intermediate piles.
15 September 2015: David Baker presented a paper entitled “King Sheet Piling (KSP) – a fundamental and innovative advance on past sheet piling practice” at the International Society for Soil Mechanics and Geotechnical Engineering’s XVIth European Conference on Soil Mechanics and Geotechnical Engineering in Edinburgh in September, 2015. This prestigious conference attracted over 1,150 delegates made up largely of leading practitioners from 65 countries.
