Overview

Value: £91k

Specialist piling was awarded the contract to install 212 contiguous piles for a new apartment development in Poole. Contiguous pile walls (cast in-situ bored or CFA) – this wall method is often used in permanent applications. Structural piles are installed at close spacing’s typically with a 100mm gap between piles. The soil is therefore exposed during excavation but will often self-support temporarily due to “arching”.

This method is suitable in a variety of soils where groundwater lies below the maximum excavation depth.
