Project at a Glance Application Retaining wall Subgrade/Soil Claystone and sandstone Location Northern England Region Western Europe Installation Date 2006 Client Barratt Homes, a nationwide developer of new houses and apartments in the UK
Building a Green Retaining Wall in a Residential Neighborhood in Northern England Challenge The developer of this residential project needed to stabilize a claystone/sandstone slope to enable construction of adjacent apartment buildings (at distances as little as 1.2 m from the buildings). The soil suffered from erosion and poor bearing capacity. To gain resident approval, the solution had to be strong and aesthetic. Since the wall would be visible from many of the properties, residents demanded a green-faced solution to suit the surrounding park landscape requirements.
