CuTex Copper Composite Root Barrier

Advanced Protection Against Invasive Root Systems

CuTex is a permeable geocomposite root barrier engineered for high-performance control of invasive plant species, including Japanese knotweed. The system consists of a copper sheet mechanically encapsulated between a woven polypropylene geotextile and a high-strength nonwoven polypropylene geotextile. This composite structure provides both durability and flexibility for integration into a wide range of civil engineering and landscaping applications.

CuTex functions by releasing low levels of copper ions (Cu²⁺), which create a localised inhibition zone in the surrounding soil. Root tips approaching this zone detect the copper and naturally alter their direction of growth, preventing penetration through the barrier. The release of copper is minimal and controlled, posing no risk to surrounding ecosystems.

Mechanism of Action:

• Root growth tips exhibit a natural aversion to elevated copper concentrations.
• Upon approaching the barrier, roots are redirected away, effectively containing invasive growth without causing harm to the plant or soil environment.

Key Features and Benefits:

• Proven control of invasive species, including Japanese knotweed
• Direct protection for utilities, foundations, and other below-ground infrastructure
• Durable, permeable structure allows water and air flow while blocking root ingress
• Environmentally responsible – minimal copper release with no ecological burden
• Long-lasting and easy to install in both new and retrofit applications
