Nicholls Lane, Stone, Staffordshire

OVERVIEW

This housing development required a retaining wall solution but presented challenges in terms of limited space and existing services. Two retaining walls were required at the sides of the entrance to Nicholls Lane housing development. While a Geogrid Reinforced Backfill method was appropriate for the Secura Grand retaining wall on the righthand side of the development, the retaining wall on the left was met with the challenges of limited space and existing services. The highway boundary limited the amount of space available to construct the retaining wall on the left- hand side. The existing services present within the retained soil caused further complexities. On this occasion minimising excavation was crucial due to the services within the retained soil. Efficient use of land was vital as the Secura wall didn’t have the room at the back for geogrid or for no-fines concrete backfill. It was desirable that both walls at the sides of the entrance looked the same despite their different conditions.
