CuTex

CuTex is a permeable geocomposite root barrier consisting of a copper sheet mechanically encapsulated between a woven polypropylene geotextile and a high strength nonwoven polypropylene geotextile. CuTex functions not only as a physical barrier, but also as a chemical barrier.

CuTex - Copper Composite Root Barrier

CuTex is a permeable geocomposite root barrier system consisting of a specially formulated copper sheet mechanically encapsulated between two high strength geotextiles. 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 undergo a progressive collapse.

The copper acts as a signal layer that all plants avert their growth from. CuTex only releases minute quantities of the copper ion and is a safe, yet effective root growth blocking material.

CuTex can provide direct protection from invasive weeds and plants. Particularly the risk posed by Japanese Knotweed to environments such as utilities’ infrastructures and foundations, across a wide range of industries including construction, highways, rail and water.

CuTex functions not only as a physical barrier, incorporating strong and durable geotextiles, but also as a chemical barrier. It acts by releasing Cu2+ ions into solution. Confocal laserscanning microscopy and differential contrast interference microscopy was used to analyse the morphology of root tips grown in the presence and absence of CuTex. The results demonstrated that when root tips approach the zone of inhibition they undergo a progressive collapse. The dividing cells at the very tip of the root (the meristem) die off and the cells above the meristem differentiate.

The localised copper toxicology only affects the root exposed to the zone of inhibition making CuTex a safe and effective material for blocking root growth. Over time CuTex releases Cu2+ ions into the soil creating an effective chemical barrier.

Cutex has been independently tested by The Centre for Plant Science at the University of Leeds; the research verified Cutex as a safe and effective barrier for Japanese Knotweed and other invasive species.

This innovative root barrier is truly multi-purpose and suitable for many applications, especially where water and nutrient flow is important. Conventional root barrier often creates a ‘wet side’ once it has been installed which attracts plant roots while CuTex alleviates this problem as it is permeable.

CuTex can provide a direct protection from root intrusion to foundations and drains, landfill caps, roads, railways, dams and green roofs.

 


 

Examples of Cutex Uses

  • Burial cell lining for Japanese Knotweed and other invasive plants
  • Vertical root barrier on land/development boundaries
  • Tree root barrier and bamboo planters
  • Protection of vertical & horizontal foundation faces
  • Protection layer under new concrete foundations
  • Capping of containment bunds
  • Lining of service trenches (rail and highways)
  • Water outfall pipe joints where Japanese Knotweed is present

 


 

Cutex & SUD’s

SUDS are drainage systems that are environmentally beneficial, causing minimal or no long-term detrimental damage. They are often regarded as a sequence of management practices, control structures and strategies designed to drain surface water efficiently and sustainably, while minimising pollution and managing the impact on water quality of local water bodies.

The use of root barriers to prevent the spread of Japanese Knotweed has traditionally involved the use of impermeable membranes which prevent the free flow of water within soils, thus contributing towards poor drainage and potential flooding.

An important characteristic of CuTex is that it remains permeable while still preventing the spread of Japanese Knotweed and other invasive species.
