Sheet Piling (UK) Ltd are leading experts in the design and construction of Steel Intensive Sheet Pile Basements. This innovative solution specifically involves the use of sheet piles as the permanent sheet pile retaining walls for underground basement construction and can be utilised on underground car parks, pumping stations, basement, storage tanks and many other applications where underground retaining structures are required.
Working closely with leading developers, consulting engineers and contractors from initial concept stage, Sheet Piling (UK) Ltd are able to offer invaluable advice to produce Value Engineering solutions for any permanent basement construction. Often this advice results in alternative permanent sheet pile basements being specified which offer significant cost and programme benefits over traditional reinforced concrete basement construction and also secant or contiguous piled walls.
Sheet Piling (UK) Ltd are able to offer installation techniques to allow basement construction in even the most restricted and environmentally difficult locations using our specialist equipment.
Through our vastly experienced in-house design team, steel sheet piles are designed to support both temporary and permanent horizontal soil loads and also if necessary to carry vertical superstructure loads from any building construction above.
Designs are carried out to current EuroCode standards and relevant industry guidance documents including CIRIA C760 ‘Embedded Retaining Walls: Guidance for Design’, ‘Steel Construction Institute’ Technical Document SCI P275 ‘Steel Intensive Basements’ and Highways Agency DMRB BD42/00 ‘Design of Embedded Retaining Walls and Bridge Abutments’. A design life of up to 120 years can be accommodated for the permanent basement structure by using sacrificial steel on the sheep out section or protective paintwork systems.
Sheet Piling (UK) Ltd have developed a range of systems to ensure a 100% watertight basement construction is achieved which includes non-structural welding to the exposed sheet pile interlocks and watertight wall / basement slab connections. All these construction details ensure a watertight construction which meets the waterproofing requirements of BS8102:2009 ‘Code of Practice for Protection of Structures against Water from the Ground’.
All welding works are carried out to specific Lloyd’s accredited Welding Procedures with associated Welder Qualifications, Acceptance Criteria and Testing Regimes to ensure the highest levels of quality are achieved for the critical waterproofing works. A full insurance backed warranty is provided for the permanent basement solution which covers both design and waterproofing.
