Yellow Arrow

RB have developed an innovative high production cast in situ displacement piling solution. CDA offers an alternative method to traditional CFA piles, providing a more practical and cost-effective solution for your project. CDA piles are straight shafted bored displacement piles which provide enhanced capacity when compared to traditional auger techniques along with generating minimal spoil.

WHAT THEY’RE USED FOR

CDA piles are suitable for light to moderate loaded piles, typically up to 500kN and can be utilised in a range of soils including stiff clays, silts and loose granular soils.

THE PROCESS

RB rigs are equipped with modern technology to record, monitor and control the installation process, ensuring high quality piles are constructed.

Our bespoke displacement tool penetrates the working platform and underlying soil to a depth predetermined by our experienced Design Engineering team. Once design depth is reached concrete is pumped through the rig as the CDA tool is extracted and the pile is concreted back up to the working platform. The required reinforcement for the pile is then installed.

WHY THIS METHOD?

  • Manufactured in-house, ready for immediate dispatch

  • Quiet installation

  • More efficient and cost-effective

  • Shorter piles to achieve required loadings

  • Quicker installation

  • Reduced spoil compared to traditional CFA piling
