CuTex as a preventative strategy for invasive weed management
across the North West.

Get professional help for the implementation of CuTex as a method to prevent Japanese Knotweed.

How to prevent the spread of Invasive Weeds

At Helmrig Ltd, we have been dealing with invasive weeds for many years, and we have used various methods in the past to control and prevent the rapid spread of Japanese Knotweed. We have found the most effective way to combat it is by using CuTex, as part of a wider preventative strategy for affected land. We are proud to supply and install CuTex across the North of England and Scotland as an effective solution for invasive weed management. Get in touch with us for more information on CuTex, advice on invasive weed survey options and treatment quotes now.

CuTex – an extremely effective method to dealing with Japanese Knotweed and other Invasive Weeds

CuTex is a copper composite root barrier that has proven an extremely efficient method of preventing ingress of Japanese Knotweed and other invasive weed species. In the past we have used various weed barrier options before adopting CuTex as our go-to method of dealing with this pernicious weed as part of a wider strategy to ensure your land is no longer compromised. As a permeable, geocomposite root barrier, CuTex still allows for soil drainage while creating a ‘zone of inhibition’ for root growth at the source through safely releasing Cu2+ ions, this creates a localised zone which causes roots to undergo a progressive collapse. Using a specially formulated design, CuTex consists of a copper sheet encapsulated between two high strength geotextiles.

The copper in the material acts as a signal layer that plants can grow from, with only minute quantities of copper released safely into the soil to prevent root growth which will not affect the biomass of surrounding plants. Typically, roots will cease to grow near this around 15mm from the barrier and nearby seeds will fail to establish. Through installing CuTex during development, this can provide an effective protection from invasive weeds and plants and avoid costly damage in the future from the extremely problematic Japanese Knotweed. This is particularly useful for the construction industry where it is essential to control this invasive native species before laying tarmac.
Recently, CuTex received RIBA accreditation for use as an Invasive Plant Root Barrier as part of a development.

Treatments for Japanese Knotweed

Helmrig Ltd can advise on the most appropriate root barrier designed for your situation and can develop and install a superior range of specialist root barriers to meet the varied demands of civil engineering, commercial development and tree related subsidence projects, together with issues with residential properties. Manufactured by Geofabrics, CuTex is an all-round solution to providing a safe and effective barrier to Field Horsetail (“Mare’s Tail”). We are proud to represent this product as a distributor across the Northwest and Scotland and have found it to give excellent results across a wide range of scenarios. Please see the reports and information provided below and get in touch to chat to us about how we can use CuTex to help you remove and control Field Horsetail on your property.

Field Horsetail background
  • Does CuTex inhibit root growth?
    To assess whether CuTex can effectively inhibit root growth the University of Leeds used a range of approaches with different plant species. Testing in a sterile culture using Arabidopsis Thaliana demonstrated how CuTex creates a ‘zone of inhibition’ whereby roots grow towards this zone, but then ceased at approximately 1.5cm from the composite. Even when seedlings were established at different distances all roots stopped at this zone, and seedlings trying to establish within the zone failed to do so.
  • Does the effectiveness of CuTex increase with time?
    CuTex in soil will effectively form a chemical barrier as the Cu2+ ions diffuse into the soil. It was hypothesised that the effectiveness of the CuTex increases with time. This was tested by pre-incubating CuTex in an agar media for a period of 4 weeks following which time seeds were sown. The plates where the CuTex had been allowed to incubate indicated a much stronger and larger zone of inhibition abolishing the growth of seeds.
  • Is CuTex safe?
    The biosafety of CuTex was tested by assessing how it affects the overall health and growth of plants. Whilst CuTex prevents plants from growing through the composite and within the zone of inhibition, the effects were shown to be relatively localised. CuTex was not shown to negatively affect the biomass of surrounding plants.
  • How does it work?
    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 laser-scanning microscopy and differential contract 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.
