Root barriers prevent root penetration into the waterproof membrane. Dependent on the roof membrane and types of plant materials chosen for a project, we provide a range of materials that can be used as a root barrier. We off er LLDPE, HDPE and PVC Root Barriers, each with its own specifi c applications.
