CHAD
PILES

Yellow Arrow

Continuous helical auger displacement (CHAD) piles offer an alternative solution to CFA piles. This piling method can penetrate tougher ground conditions compared to conventional CHD piles. By adopting RB’s CHAD solution, this technique also reduces the amount of spoil excavated from the pile when compared to traditional CFA solutions.

WHAT THEY’RE USED FOR

CHAD piles are mostly used within the residential, commercial and industrial sectors. This piling method is most suited for medium to high loads. It can be used in a variety of soils including cohesive soils such as clay and non-cohesive soils. Some examples include, gravels, glacial tills and contaminated ground.

THE PROCESS

Continuous helical auger displacement piles are formed by drilling the required design depth using a string of hollow stem augers. Soil is then excavated from the ground and brought to the surface. A cage system is then re-enforced into the ground and the bore is filled with concrete, creating the pile.

WHY THIS METHOD?

  • Reduced spoil compared to CFA piles

  • Able to penetrate denser strata than regular CHD piles

  • Improves soil strength

  • Can be used for all foundation applications where bearing piles are required for structures

  • Virtually vibration-free

  • Ideal for urban or sensitive locations

  • Quick installation benefitting contract programming
