Root Solutions extruded root barrier panels offer the simplest way to keep tree roots from damaging sidewalks, roads, and structures. Whether used as a linear barrier or surrounding a rootball, the flexible panels will contour to irregular or difficult locations. The self-locking channels require no glue or additional parts, and slide together in seconds. Made of a blend of 100% recycled high-density and low-density polyethylene, they won’t become brittle, harden, or fail over the life of a project.
