Q.Tree Root Protection During Construction
Hello, We have a back land residential development site with planning permission to build 4 detached houses. As part of the planning conditions tree roots have to be protected before any work can commence on site and remain throughout the construction period . There is an existing driveway that will provide access to the 4 new houses. The driveway already provides access to an existing house beyond the site. The driveway is unmade and well compacted having been providing vehicle access to the existing house beyond the site for 40 years. There are several established trees next to the driveway, with roots running under the driveway. Fencing that is often used to provide tree root protection cannot be used to provide tree root protection in this case as this would block access along the existing compacted unmade driveway to the existing house beyond the site whilst construction of the 4 houses is undertaken. Given the circumstances and what we need to achieve whilst construction is carried out please can you recommend a temporary tree root protection solution for the trees next to the compacted unmade driveway.

Construction vehicles traveling over that unmade driveway will surely compact the soil even further, to the detriment of the trees. If fencing is out, I suggest finding a new pathway for the construction that will avoid all the trees. Here is more:
