Tree Root Barrier
18″ Standard Duty
Protect sidewalks, driveways, septic systems, and more—before roots do the damage.
Why It Works
- Crafted from 80 mil (2 mm) recycled HDPE, proven to handle up to 155 lb puncture strength (ASTM D 4833)—ideal for small to medium trees such as oak or maple.
- At 18″ deep, this barrier safely redirects lateral roots downward, preventing costly heaving in hardscapes.
- Unlike brittle panels, the flexible, continuous roll smoothly adapts to curved trenches and larger planting areas.
Key Benefits
Durable & Built to Last
Made from recycled HDPE designed to last 100+ years underground
Single-Piece Genius
No weak joints—one seamless roll means fewer failure points
Easy to Install
Simply trench, insert, and backfill. Cut easily with a utility knife. Lay in the sun for flexibility
Liability Protection
Prevents sidewalk uplift and tripping hazards—safeguard walkers, wheelchairs, and reduce legal risks
Smart Water Management
The impervious HDPE also acts as an underground water divider, protecting foundations and septic systems
Ideal For:
- New or young trees—establish root direction early for long-term control
- Single-tree pits or continuous planting zones—install in circular or linear trenches
- Areas prone to root heave—near sidewalks, driveways, pipes, and foundations
Installation Tips
- Locate underground utilities before digging
- Dig trench to barrier depth, or leave 2″ exposed for mulch retention
- Unroll the barrier and position it vertically—bend gently to navigate curves
- Overlap pieces by a couple of inches and secure with our stainless straps
- Backfill and water—monitor surface roots for trimming
