THE CORE TREE ROOT PROTECTION ( TRP ) SYSTEM

The CORE Tree Root Protection ( TRP ) System is a CE certified cellular confinement system that provides guaranteed protection for the roots of mature trees from pedestrian and vehicular traffic . It distributes the weight of the traffic which in turn prevents subsoil compaction around the roots .
With the correct fill material , it is completely porous allowing continued water permeation and gaseous exchange to ensure the protected tree stays healthy .
Why is Tree Root Protection Needed ?
Due to the rate of urbanisation within the UK , it ’ s becoming increasingly common to find trees located in areas of development with Tree Preservation Orders ( TPO ’ s ). TPO ’ s ensure the protection of mature trees , especially when construction work is being carried out nearby .
Our CORE Tree Root Protection ( TRP ) cellular confinement system offers a compliant solution to creating a driveway , car park , road , or track for temporary site access . The system creates a threedimensional erosion barrier and structural bridge that uniformly distributes weight-bearing loads – this prevents unwanted ground compaction in and around the feeder roots of the tree .
Failure to comply with a TPO is treated as a serious offense towards the environment and can result in a £ 20,000 fine . 90 % of tree roots are found within 1m of the surface and extend to a distance equal to approximately 65 % of the tree \ s overall height . Making it impossible to build a sustainable surface using traditional methods that can take vehicular traffic without digging and disturbing the feeder roots of the tree .
