Root Barrier

Protection from invasive weeds

PA Geotechnical provide root barrier solutions for a variety of applications.

Root Barriers can be used for simple tree root problems and landscaping applications, to engineered barriers preventing the horizontal growth of Japanese Knotweed.

PA Geotechnical has a range of materials including Nicotarp 100 PE based coated fabric and the Nicoflex range of reinforced polyethylene monomers.

From basic solutions to re-direct root growth and eliminate surface rooting, providing ongoing root control in hard landscape applications, to fully welded and installed vertical root barrier projects on development sites, where Japanese Knotweed has been identified, we are able to work with clients as part of their Japanese Knotweed Management Plan.
