Due to their versatility, driven piles are widely used and are suited PRECAST DRIVEN PILING TECHNIQUE to most ground conditions. They are particularly suited where the founding strata is overlain by soft alluvial deposits or made ground. Driven piles are unaffected by ground water and don’t generate spoil on site.

WEMBLEY STADIUM, LONDON – CONTIGUOUS PILE WALL BORED PILE RETAINING WALLS

CONTIGUOUS PILE WALLS Used in locations where water retention is not a consideration and soils are stable, contiguous bored walls dispense with interlocking piles completely. Typically a gap of 150mm to 300mm is left between the piles. GAP BETWEEN THE PILES CAN VARY DEPENDING ON SOILS

SECANT PILE WALLS (HARD / HARD AND HARD / FIRM) FEMALE PILE Secant walls are particularly suitable where high water retention is a consideration as they have a positive interlock between adjacent concrete piles. Both male and female piles can be reinforced enabling high lateral loads to be supported. MALE PILE FEMALE PILES CAN BE REINFORCED

SECANT PILE WALLS (HARD / SOFT) FEMALE PILE This wall is used where considerations of height and lateral deﬂ ection are less critical. Female piles use self hardening slurry or unreinforced concrete to provide the seal between the reinforced concrete male piles.

BBGE PRECAST PILE FACTORY – ZERO WASTE TO LANDFILL SUSTAINABLE SOLUTIONS

OUR FACTORIES Our two factories in Scotland and Nottinghamshire manufacture all our precast piles. This means that as well as having full quality control we are also able to ensure they are sustainable. This includes the use of 100% harvested rainwater, 99% recycled steel reinforcement and a minimum of 25% cement replacement in the production of all our precast piles. Having our own factories also means that we are able to produce non standard pile sizes and reinforcement to meet specifi c needs, as well as setting up modular pile production units as required. GEOTHERMAL LOOPS WITHIN CFA PILES GEOTHERMAL PILES Providing Geothermal Piles for use in ground storage systems is one way that we can help with the provision of renewable energy and reduce carbon emissions.
