Resin Tree Pits

Tree pits in urban settings can often look untidy. They usually consist of loose aggregate, tree pit grills or just bare soil.  Trees new and established require water and air so the tree pit surface must offer opportunity for both in abundance.

Addagrip Terraco offer a resin bound tree pit product specifically designed to provide an attractive and aesthetically pleasing porous paving system for tree pits in urban and rural schemes.

Addastone TP

Addastone TP is available in a UV stable Polyurethane resin binder which is mixed with our range of 6-10mm natural or recycled aggregates to form a decorative alternative to loose gravel or soil.

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. The bound aggregates ensure that there are no issues with displaced soil or stones and the surface deters weeds.
