Steel intensive underground car park constructed for the East Midlands Examination Board in Birmingham.
The steel sheet piles were designed to support both temporary and permanent soils loads and also to carry vertical axial loads from the three storey steel framed building above. The sheet piled structure was made watertight to meet the requirements of BS 8102:1990 grade 2 as defined by CIRIA report 140 using our SPUK Lockblock Hydrostop System.
The piles were designed for a service life of 75 years which was accomplished using sacrificial steel thickness.
The site was enclosed on three sides by existing occupied offices and noise/vibration levels had to be controlled to an exceptionally low level.
The sheet piles were installed to the underlying sandstone strata at approx 8 metres below commencing installation level using our U.P. 150 Silent Vibration Free Pile Press equipment. Two piles in each side of the basement were then dynamically load tested to ensure that the appropriate load capacities had been achieved. The exposed pile faces were wire brushed and painted with a conventional oil based paint system as part of the main contract works.

Typical example of steel sheet piles used as permanent works for the construction of an underground C.S.O. (Combined Storm Overflow chamber) for the West of Scotland Water Authority. Once the sheet piles had been installed a permanent reinforced concrete capping beam was constructed and tubular struts fixed to facilitate excavation for the base slab works.
The sheet pile installations were sealed using our SPUK Lockblock Hydrostop System.
The photo alongside shows a typical base slab/sheet pile interface with a continuous steel puddle flange water bar welded to the sheet piles. A hydrophilic strip is bonded (using hydrophilic glue) to the steel plate to further enhance the integrity of the seal.
Where appropriate, for example in deep basements installed in soils with a high water table, shear studs or rebar can be connected to the piles to resist hydrostatic uplift.
