Context

Phi Group's expertise in retaining walls is being utilised to full effect on West Dunbartonshire Council's project at Bonhill, where 26 highly energy-efficient homes are being constructed for social rent. The sloping site meant that some substantial retaining walls were required.

Project detail

Phi Group's BBA-certified Permacrib timber crib system was chosen as the method of retention as it is sustainable, cost effective, quick to construct and aesthetically pleasing.

The company's Dunfermline office was involved at an early stage to provide design assistance and ensure the site was effectively used and the most buildable solution employed.

When complete there will be four Permacrib walls constructed with a total length of 285m, a maximum retained height of nearly 4m, and a face area of 850m2.

As part of the works Phi Group also supplied and placed the granular backfill material, supplied and installed fencing to the top of the Permacrib wall and the climb prevention mesh to the front face.
