Retaining Walls

Bachy Soletanche has extensive experience in the design and construction of structural retaining walls for all temporary and permanent requirements.

Our expertise spans a wide variety of ground conditions, in both urban and green field environments.

Bored pile walls (contiguous or secant) can be the ideal solution for more restricted sites when the wall is constructed using continuous flight auger techniques or 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.

A variation of this technique was developed by our engineers for shaft construction on the Copenhagen Metro Project, using sheet piles driven within a bentonite cement slurry.
