Tree Root Barrier
30″ Heavy Duty
Maximum protection for large trees and critical infrastructure—when deeper is better.
Why It Works
- Engineered from 80 mil (2 mm) recycled HDPE with proven 155 lb puncture strength (ASTM D 4833)—perfect for large mature trees like oak, maple, and pine.
- At 30″ deep, this barrier provides superior root control, redirecting even aggressive root systems away from critical infrastructure.
- The flexible, continuous roll design handles complex installations around large tree canopies and extensive planting areas.
Key Benefits

30″ depth provides maximum root control for large trees and aggressive root systems
Infrastructure Shield
Protects foundations, underground utilities, septic systems, and high-value hardscaping
Professional Grade
Built for commercial landscaping, municipal projects, and demanding residential applications
Seamless Installation

Century Lifespan
Recycled HDPE construction designed to last 100+ years underground without degradation
Ideal For:
- Large mature trees—oak, maple, pine, and other trees with extensive root systems
- Commercial and municipal projects—parks, streetscapes, and public infrastructure
- High-value protection zones—around foundations, underground utilities, and premium hardscaping
- Problem areas—where previous root damage has occurred or shallow barriers have failed
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
