The document describes a project to build an access pathway into Castle Gardens in Leicester, England. The pathway needed to be built 1.8 meters above the existing path to reach a new entrance, but the area contained tree roots that could be damaged by ground compaction. Cellweb TRP, a geosynthetic material, was used to construct the raised pathway. It was layered to create the elevated structure and distributes weight to prevent compaction of the tree roots below. The pathway was successfully built through the rooting area while maintaining a natural appearance.

Case Study
Cellweb®
TRP
Pravin Godhania, Leicester City Council
Leicester City Council required a sloped path from the new entrance to
the existing path in Castle Gardens. The problem for the council was that
the new entrance was 1.8m higher than the existing path and it was in a
tree rooting area. Cellweb®
TRP was adopted because it can be layered to
create the raised path and because it will distribute the weight of its own
infilled layers, ensuring the increased levels do not compact the rooting
areas.
