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.

What does the word "control" mean in the referenced studies?
In these studies the term "control" is the test when the CuTex barrier is not used. Think of it as "without CuTex".
Does CuTex inhibit root Growth?
The most effective demonstration of CuTex was a setup using an upper layer of vermiculite and a lower compost
layer separated by CuTex. The vermiculite contains no nutrients to support the development of the plant, and
thus the long-term growth and survival of the plant depends on growing through the CuTex. The experiment was
conducted using a number of plant species, including Japanese Knotweed, with the CuTex being assessed against
a control fabric.
Japanese Knotweed is a strong growing herbaceous plant native to
Japan, Taiwan, China, and the Korean
peninsula. It was introduced into
Europe in the mid-19th Century as an
ornamental plant. The plant has
thrived in fertile European soils and is
now classified as an aggressive weed
species. The plant has a significant
negative impact on the environment
where it occurs. Japanese Knotweeds
stout rhizomes can push through
asphalt, building foundations, cracks
in concrete, retaining walls and even
It out-competes other species affecting landscaping
programs, it disturbs the aesthetics through
the accumulation of litter in dense thickets which
encourages vermin and it increases the maintenance
costs of buildings. It can also disturb local ecosystems
by blocking migration of native plants and animals.
This can add huge costs to development and
Contaminated soil must be treated as controlled
waste. Additionally, the plant is capable of obscuring
railway signals and road signs as well as causing
trip hazards in paving. Hence, Japanese Knotweed
can cause excessive costs for remediation, lead to
prosecution and/or compensation claims, especially
from neighboring sites, physical damage to buildings,
hard surfaces and harm to the environment (through
the repeated applications of herbicides).
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 analyze 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
The localized 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 barrier orders typically ship same day (M-F) if order is placed before 12:00 noon EST. Transit times displayed in the map are listed in business days and are approximate.
The transit times displayed on the map is for standard ground shipping.
