A Geo-composite root barrier system consisting of a copper sheet mechanically encapsulated between a woven polypropylene geotextile and a high strength non-woven polypropylene geotextile. The copper acts as a signal layer that plants avert their growth from. The copper foil only releases minute quantities of the copper ion. These do not constitute an ecosystem burden, or impact on groundwater.
Provides a physical and signal root barrier.
