Permanent 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. 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.

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 EuroCodes, relevant industry standards and the 'Steel Construction Institute' Technical Document SCI P275 'Steel Intensive Basements'. A design life of up to 120 years can be accommodated for the sheet pile basement by using the sacrificial steel thickness of the sheet piles or specialist coatings.

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.
