If you want a more permanent retaining wall, then contiguous pile walls are the answer, and at the East Coast Group of Companies, we can provide everything you need. This particular method involves installing the piles closely together, with only a small gap between them, exposing the retained soil. The exposed soil will, however, ‘self-support’ via a process known as ‘soil arching’, during the excavation process.
If you choose this method, the retaining walls may be created either as cantilever walls or you can draw on additional lateral support from anchors or bracing. Contiguous pile walls are also suitable for a variety of soils, where groundwater lies below the maximum excavation depth.
