The Addastone TP (tree pit) systems are designed to provide an attractive and aesthetically pleasing porous paving system, using a variety of natural or recycled aggregates. Available in either Epoxy (EP) or a UV stable Polyurethane (PU), the resin binder is mixed with a suitable natural or recycled aggregate with a typical grading of 6-10mm.

The open texture achieved provides a highly porous surface allowing the tree roots access to both air and water penetration.

As Addastone TP 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.

Addastone TP is not capable of supporting vehicular traffic. However, by using Addastone Matrix Paver Trays infilled with the Addastone TP Resin and aggregate, areas can be trafficked, subject to being applied onto a suitable base.

Planting:

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.

Kerb edging and collar detail:

A suitable edging detail and collar should be installed around the base of the tree and at the edges as required. The use of the "Permaloc Edging System" or similar can be used to provide smooth curved edges or collar sections around the base of the tree. The Permaloc Edging System is available in natural aluminium; further information is available at www.rtslimited.uk.com.
