Our Knotweed and Root Barriers are purpose made specialist products designed to provide proper protection against roots and rhizomes. They are manufactured from multi layered High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE) to provide protection you can rely on. They are also UV stabilised for added durability outdoors.
Japanese Knotweed has gained notoriety by spreading across the country since it was introduced to Ireland in the 1800’s as a decorative plant. This invasive species is very persistant and almost impossible to eradicate. To make matters worse, the roots and rhizomes have the ability to grow through even concrete and tarmac. It is therefore necessary to protect important structures in infected and high risk location against this menace. Our Knotweed 600 consists of a woven HDPE Base material which is reinforced and coated with a triple layer film of LDPE (Low Density Polyethylene). The Membrane is UV stabilised and suitable for outdoor applications.
