CHD
PILES

RB Continuous helical displacement (CHD) Piles form a cast in situ pile without producing any spoil. An ideal solution for contaminated sites. CHD is often a popular choice in reducing waste going off-site, vibration and noise pollution.

WHAT THEY’RE USED FOR

CHD piles can be used across various sectors and construction projects. This technique is most commonly used within the residential and commercial sector. Suited for light to moderately loaded piles, and can be used in a variety of soils. Some examples include sands, gravels and cohesive soils such as soft to stiff clays.

THE PROCESS

Like CFA methods however the auger string, instead of breaking down the soil for extraction from the bore, forces the ground away from the bore laterally. Due to this reason, this technique is classified as a bored displacement piling method – unlike the CFA piling method which it a replacement pile.

WHY THIS METHOD?

  • Alternative to CFA piles

  • Cost effective as it reduces minimal waste

  • Ideal for contaminated sites

  • Can be used for cohesive and non-cohesive soils

  • Improved soil strength

  • Improved pile capacity and load transfer
