Tree roots can cause serious damage to underground structures. BioBarrier is a proven solution to stop roots for a minimum of 15 years by creating a chemical barrier that prevents root growth. BioBarrier works invisibly to deflect roots along hardscapes, under pots, and in dams and levees. The nodules in BioBarrier slowly release Trifluralin, which prevents root division and the expansion of roots without impacting tree health. Works more proactively than physical barriers, which can create more problems. BioBarrier stops continuous root growth, which helps overall tree health. Root system includes a standard drainage fabric to allow water, air, and nutrients to pass through.
