Driven Precast Piling

Due to their versatility, driven piles are widely used and are suited to most ground conditions. They are particularly suited where the founding strata is overlain by soft alluvial deposits or made ground.

Basic Techniques

Piles are manufactured off site in standard lengths, and driven into the ground using a hydraulic hammer until the required depth/resistance is reached. Where greater depth is required, the lengths are jointed together using the BBGE Multijoint or a pinned UNIjoint. In this way, piles can be as long as required to meet the load bearing specifications. Driven piles can also be raked up to 1:3 depending on hammer weight and pile size.

Pile Manufacture

With a combined capacity of over 800,000 metres per annum, BBGE has two permanent pre-casting facilities in Nottinghamshire and in Scotland. These facilities give BBGE the ability to control precisely the specification and quality of piles used. Piles are manufactured in 1 metre increments from 5 to 14 metres and in four standard sizes from 187 to 350 square mm.

BBGE is also experienced in producing non-standard pile sizes and reinforcement to meet specific needs, as well as in setting up modular pile production units in the UK and overseas.

Contaminated Land

Where piles are required to penetrate contaminated material, modifications can be made to the pile section in line with Environment Agency guidelines.

Noise

Where environmental disturbance needs to be kept to a minimum and other piling techniques may be unsuitable owing to ground conditions, BBGE offers the most up-to-date enclosed hydraulic hammers, which keep noise disturbance to a minimum.
