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.
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.
