Piling
Hollow Stem (CFA) Piling for Poor Ground Conditions
CFA piling
Where the ground won't allow normal augered piles, DW Clayfield can install hollow stem piles, also known as continuous flight auger (CFA) piles. Concrete is pumped down through the hollow auger as it is withdrawn, so the bore stays supported throughout.
We own all of the equipment for this work, including our own on-site concrete batching facility.
DW Clayfield can design and construct your foundations, including the ring beams and ground slabs. Give us a call to discuss your requirements.
