Requirement

Driveway access was granted through a Root Protection Area (RPA) at planning stage for five new dwelling houses on the basis of a proposal to use a concrete slab set on concrete piles to protect the tree roots.

However, it transpired the proposed solution was not workable due to a gradient across two planes on the proposed driveway.

Green Grid Systems was approached to see if their steel tree RootBridge system could do the job.

Work undertaken

Green Grid was able to modify its heavy-duty root bridge system to accommodate the gradient across the two planes – something that was not possible with the original concrete option.

The root bridge is rated to take vehicles up to 30 ton, with stub legs set at specific angles and heights to connect to the piles and manage the gradients.

The system in this project was left as a mesh grid finish at the client’s request, with a heel-friendly mesh size and anti-slip serrations.
