Continuous Flight Auger Drilling (CFA)
Continuous Flight Aauger (CFA) Piles are Hollow Auger Piles also know as Deep Foundations Cast in Place or Helical Displacement (HDP)
Full Displacement Pile System (FDP)
Drilling with Cased Continuous Flight Auger (CCFA)
Driven Cast-In-Situ Piles (DCIS)
Ductile Piles
Secant Pile Walls
Tangent Pile Walls
Rigid inclusion or Controlled stiffness columns (CSC®)
Controlled modulus columns; CMC
Bi-modulus columns or Hybrid columns (Colonne à module mixte/CMM®)
DSM - Wet soil mixing, also known as Deep soil mixing or Mass stabilization
Vibro Concrete Columns or Vibro Displacement Columns (VDC)

Full Displacement Pile System (FDP)

This technique has many benefits of driven piles without the disadvantages of noise, vibration, joints and waste.

FDP are a type of reinforced concrete pile that are built in situ. This technology combines the advantages of driven (displacement piles) and bored piles (piles without displacement).

A displacement head is drilled into the soil with high torque and crowd. Displacing of the soil results in a densified skin area with increased bearing capacity. Concrete is pumped through the hollow stem. As the tool is rotated in one direction during extraction, it is possible to recompact loose sidewall areas.
