RB (RootBridge) Light is a tree root bridge system designed for light vehicular traffic, including car parking spaces and access roads. It provides a 15kN point load capacity and is capable of supporting vehicles with a 3 tonne axle load.
RB Light has a low overall structure height of 85mm and can be installed with different length groundscrews in order to accommodate various soil conditions. The system can be overlaid with paving or asphalt, and can be finished with an optional heel-safe mesh grid.
- Light vehicular traffic: access roads and car parks
- Low overall depth (85mm)
- 15kN point loads; 3 tonne axle loads
- Paving, asphalt and heel-safe mesh grid finishes
- Installed in 1m x 1m sections
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 rootzone 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.
