Our 80 mil HDPE tree root barrier is built for demanding containment jobs, stopping aggressive tree roots, bamboo, and other invasive plants before they damage hardscapes, foundations, or neighboring property.

At 5/64″ thick (2 mm), this root barrier delivers a smooth, impenetrable surface that redirects roots sideways rather than letting them spread unchecked. Made in the USA from UV-stabilized HDPE, it’s built to last up to 100 years in the ground. Sold in continuous 80' and 100' rolls, it lets you install one long, seamless stretch — eliminating the connection points where panel-style barriers are most prone to root intrusion.

Easy to cut with a standard utility knife and simple to join with HDPE sealant tape, the 80 mil barrier is the choice for tree planting areas, urban installations, and large-scale projects where root overgrowth could cause significant property damage.
