Available in either Epoxy or a UV stable Polyurethane, the resin binder is mixed with our range of natural or recycled aggregate with a typical grading of 6-10mm.
The open texture achieved provides a highly porous resin bound surface, allowing the tree roots access to both air and water penetration.
As Addastone Tree Pit installations are installed flush with the surrounding paving areas they have the added advantage of not becoming a litter trap that can occur with traditional tree grilles.
25mm depth - No foot traffic.
50mm depth - Light foot traffic.
75mm depth - Heavy foot traffic.
A suitable edging detail and optional collar should be installed around the base of the tree as required. To allow for tree growth, the optional protective tree collar can be infilled either with loose aggregate or an increased ratio of aggregate to PU Addastone TP resin.
The tree should be planted and anchored in urban tree soil or similar. The addition of a Greenleaf Root Rain Precinct Irrigator/Aerator and Greenleaf Root Director is also advisable.
