A porous tree pit surface made from resin bonded gravel forming a porous cap over the tree pit.

Features:

• Surface structure allows free flow of air and water to the root zone.

• Will support light vehicular traffic (when laid to a minimum depth of 75 mm).

• Avoids problems associated with loose gravel.

• A standard galvanised steel frame is available to provide an edge to the paving and bound gravel edge to support paving loading for light traffic.

• A choice of aggregate colour for different applications.

Surface preparation and application:

• The area must be clean and dry.

• 100 mm minimum infill depth is required.

• A porous geotextile to be placed at the bottom of the area to be surfaced.

• 30-50 mm of loose aggregate is placed on top of the geotextile layer. It is important to leave a space around the tree to allow for the eventual increase in trunk diameter - this area can be filled with loose aggregate and capped off with Arboresin no greater than 10 mm thick.

• Mix the washed and dried aggregate with the mixed resin and hardener and place on the loose aggregate to the required depth (50 mm or 75 mm), trowelling to a smooth finish.

• Some aggregate colours require a UV resistant resin system.

Aggregates:

• A choice of aggregates for different applications is available.

Aggregate thickness:

• 50 mm: For pedestrian only areas.

• 75 mm: For areas subject to light vehicular overrun.
