CuTex Copper Composite Root Barrier

Application

Used as vertical and horizontal root barrier and burial cell liner, tree rings and other invasive plant barriers. Suitable for housing developments, boundary line segregation, protection of utilities and foundations.

Description

A permeable geocomposite root barrier system consisting of a copper sheet mechanically encapsulated between a woven polypropylene geotextile and a high strength nonwoven polypropylene geotextile.


CuTex acts by safely releasing Cu2+ ions to inhibit root growth. The copper ions create a localised zone of inhibition which when approached by root tips causes them to avert their growth or stop growing. The copper foil only releases minute quantities of the copper ion that does not constitute an ecosystem burden or impact on groundwater.


Plant shoot/root primordia (growth tips) are averse to growing into the vicinity of copper concentrations. The roots turn their growth in a different direction when confronted with the copper foil. These principles make CuTex an excellent root barrier for Japanese Knotweed as well as other plants.


Features and benefits:

  • Provides a barrier for Japanese knotweed growth.
  • Provides direct protection from invasive weeds and plants.
  • Protects utilities' infrastructure.
