Root bridge system
RootBridge from Green Grid is designed to prevent soil compaction and root damage to existing trees within the root protection zone. It consists of a steel framework that provides a stable sub-construction that bridges the root zone and allows heavy loads to be supported across pedestrian and vehicular areas. The steel framework houses mesh grids that ensure natural water drainage, and the finished installation can also be overlaid with asphalt or paving.
Other key benefits of RootBridge include its high load-bearing capactiy and its low structure height, which enable minimum impact during construction.
