Application

Suitable for use to eliminate ingress of surface layer works materials into tree pit rooting zone and to provide additional support and stabilization for surface subbase materials.

Description

A structural twin-walled geonet used in ArborSystem tree pits selected to fulfill stringent loading requirements. GTWGNA twin-walled geonet is used over the top of RootSpace/StrataCell soil cell systems, beneath the surface layer works (build-up) to eliminate ingress of fines into the tree pit rooting zone and to provide additional support and stabilization for surface subbase materials. It also discourages root growth vertically.


This product cost is included in the metreage rates for StrataCells and RootSpace units.


Features and benefits:

  • 1 m wide rolls up to 100 m long.
  • Structural wall consisting of high strength woven strands plus second fleece non-woven fabric for preventing fines passing through.
  • Stabilizes surface layer-works.
  • Eliminates ingress of surface layer-works materials into the tree pit rooting zone.
