Vibro Concrete Columns or Vibro Displacement Columns (VDC)

Tangent Pile Walls

Tangent piles, a variation of secant piles, are columns constructed adjacent to each other along the perimeter of an excavation to form a structural or cut-off wall. Typically, the piles in a tangent wall are reinforced with steel bars or beams. Tangent pile walls offer an easy and quick construction and increased construction alignment flexibility.
