Modular pavement protection
The Root Director
Designed for the protection of pavements and hard landscape areas, the root director systems divert root growth downwards and ourwards avoiding the unsightly and hazardous root damage.
Without ribs, roots will tend to grow along the root barrier rather than downwards. In surround applications this can lead to root girdling which in the longer term could suffocate the tree. Both 2110 and 2111 have root deflecting ribs formed ino them.
- Protection for paved surrounds
- Encourages a deeper root growth pattern
- Enhances tree drought tolerance through deeper rooting
- Improves tree stability
- Integral ribs to prevent root girdling
- Optional integral irrigation/aeration inlet vents
- Compatible wih most makes of tree grille
- Simple to install

Root Director installation
- Choose your Root Director by rootball diameter: RD640 has a top opening of 580mm, RD1050 is 960mm.
- We suggest backhoe excavation of a square hole about 100mm deeper than the Root Director so that sand can be used to assist final levelling. The soil beneath the centre of the new tree should be loosened to a depth of 400mm to ensure there are no obstructions and assist root penetration downwards.
- Stake holes can be simply cut, using a stanley knife or similar, before placing the Root Director, and give firm vandal-proof support for the stakes.
- If a tree grate finishing flush with the paving is to be installed on top of the Root Director its thickness should be allowed for, otherwise the upper lip of the Root Director should be flush with the surrounding surface.
- If the original soil is suitable as a planting medium it can be re-used to backfill inside the Root Director. Alternatively your tree supplier can suggest an appropriate material.
- The backfilling outside the Root Director should be no more permeable to the roots than the undisturbed ground. Internal and external backfilling should proceed together so that the Root Director is not unduly distorted.
