Tree Root Barrier
36″ Commercial Grade
Ultimate protection for extreme conditions—engineered for the most demanding applications.
Why It Works
- Constructed from 100 mil (2.5 mm) recycled HDPE with exceptional 200 lb puncture strength (ASTM D 4833)—built for the most aggressive root systems.
- At 36″ deep, this is our maximum protection barrier, designed to stop even the most invasive trees from damaging critical infrastructure.
- The extra-thick, flexible construction withstands extreme soil conditions and heavy equipment loads during installation.
