Contiguous & Secant Piled Walls
Contiguous, or bored piles are used by mini piling contractors and cfa piling contractors to create retaining walls. We place these piles in a row. They virtually touch each other to create a box below ground for a basement, or to hold back higher ground.
With Secant piled walls, the process is in a sequence: we cut subsequent piles into previously installed piles, thus creating a seal between the units to hold out liquid or running sand. The result is a continuous, efficient structure over which an inner wall may be built.
