RootBridge is a modular steel lattice construction designed to protect tree roots where new developments, such as walkways, steps and car parking areas, are planned close to existing trees.
It protects the existing root range from harmful pressures which can lead to soil compaction, loss of aeration, drainage problems and, ultimately, the death of the tree.
With a low structure height from 75mm, the RootBridge requires minimal excavation and can easily be retrofitted.
- Protects existing root range from compression
- Modular system allows planning flexibility and expansion
- Low structure height requires minimal excavation
- Meets local authority demands for no-dig tree root protection
- No concrete within the sensitive root range
- Complies with relevant British standards
RootBridge is a modular steel lattice construction that sits on screwed-in foundations.
The structure is 75mm high.
It is installed by inserting foundation screws between the roots, up to approximately 2m into the soil, without damaging the roots.
RootBridge standard systems are suitable for loads up to 57.5kN wheel loads. Higher loads are possible depending on the ground condition.
The final surface finish of steel mesh grids can, if required, be overlaid with block paving, asphalt or resin bound.
