Bored Pile Walls

Bored pile walls (contiguous or secant) can be the ideal solution for more restricted sites when the wall is constructed using continuous flight auger (CFA) techniques or large diameter auger (LDA) with temporary casings.

We have designed and built a number of hybrid retaining walls in appropriate ground conditions as cost effective alternatives to sheet piling. Bored piles can be constructed through bentonite cement slurry with lateral loading on the wall carried by “arching” between the bearing piles. This can provide a very reliable temporary works solution.
