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.

Knotweed Barrier

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 persistent 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.

Tree Root Guiding Panel

Tree Root Guiding Panel (TRG) was designed to prevent root growth from lifting and damaging paving. Its panels feature special guide ribs which redirect tree roots deeper into the soil. The Root Guide can be used within two meters of the tree. Conventional root barriers do not guide roots and therefore offer no stability and limit the growing space. To prevent roots lifting the panels, horizontal ground anchors fix the panels in place. Our panels meet all requirements of root guidance. In addition, the TRG panels are also equipped with double top edge. The rim prevents root growth over the panels and prevents cracking entry of the screens.
