Root Barrier Cloth vs Solid Plastic: When to Use
Root Barrier Cloth: When a Permeable Barrier Beats Solid Plastic
Root barrier cloth controls roots while letting water and air pass through. Here is when permeable cloth is the smarter choice.
Table of Contents
Root barrier cloth is a permeable fabric barrier that controls root growth while still allowing water and air to move through the soil. It is the right choice when a solid plastic wall would trap too much water or where drainage must be preserved.
Key takeaways:
- Cloth barriers are permeable, so water and air pass through while roots are controlled.
- Useful where solid HDPE would block needed drainage.
- Biobarrier fabric uses time-release nodules to inhibit root growth at the barrier.
- Often chosen for large commercial and landscape areas.
Cloth vs. Solid Plastic
A solid HDPE sheet physically deflects roots and blocks water movement across the wall. Root barrier cloth instead lets water and air pass through the fabric while still controlling roots. That permeability matters in landscapes where blocking drainage could waterlog soil or starve nearby plantings.
Permeable cloth covers broad surfaces while preserving drainage.
How Root Barrier Cloth Controls Roots
The best-known permeable option, Biobarrier, is a fabric embedded with time-release nodules that create a treated zone at the fabric. Roots approaching the barrier are inhibited from crossing, while the fabric still breathes and drains. The effect lasts for many years.
Where Cloth Makes Sense
Permeable cloth is favored for broad surface applications, vegetation control around infrastructure, and any site where preserving water and air flow through the soil is important. For a hard, impenetrable line along a sidewalk or foundation, solid HDPE is usually the better tool.
Biobarrier cloth is treated to inhibit roots while remaining permeable.
Cloth or Plastic for Your Project?
| Need | Better Choice |
|---|---|
| Maximum drainage and air flow | Root barrier cloth |
| Hard, impenetrable wall | Solid HDPE |
| Large surface vegetation control | Root barrier cloth |
| Sidewalk or foundation line | Solid HDPE |

What is root barrier cloth?
Root barrier cloth is a permeable fabric that controls root growth while allowing water and air to pass through the soil, unlike a solid plastic barrier.
When should I use cloth instead of solid plastic?
Choose cloth when drainage and air flow must be preserved or for large surface areas. Choose solid HDPE when you need a hard, impenetrable line along a sidewalk or foundation.
How does Biobarrier cloth control roots?
Biobarrier fabric contains time-release nodules that create a treated zone at the barrier, inhibiting roots from crossing while the fabric still drains and breathes.
