Many of Australia’s trees, bushes and other varieties of plants take in a lot of water when faced with adverse conditions. This means that once the water is depleted from one part of the soil, the roots will begin to disperse to obtain more water. This dispersion of roots can cause significant damage to other plants, as well as walls, footpaths, and driveways. To prevent damage from root systems, install a root barrier.

Our Root Control Barrier consists of a flexible High-Density Polythene membrane designed to restrict the unwanted movement of root growth. As well as this, Root Control Barrier is lightweight and easy to install and maintain, and it is a far less expensive and flexible solution to invasive root growth than more difficult solutions such as sheet metal and concrete.

Features and Benefits:

  • Stops the spread of roots to unwanted areas
  • Reduces damage to walkways, driveways, garden beds, roads, and infrastructure
  • Easy to install, can be cut to shape, and is cost-effective
  • Joined by butyl tape to form a tight seal, blocking moisture and vapor
  • UV stabilized, high-density polyethylene to ensure long-term protection
  • Root Control Barrier retains moisture around the root ball

All of the features of the Root Control Barrier are designed to allow it to tree roots damaging your property while still allowing it to easily integrate into its environment.

Root barrier installation process

1. Dig a 10cm wide trench around the tree. You may need a 360* barrier OR just a single side barrier depending on your tree location and where you wish to prevent root growth.

2. The depth of the trench should be from 600mm to 1000mm, depending on how aerated the soil is. Few roots grow below 1000mm.

3. Once you dig the trench, insert the root barrier, flat against the side of the trench wall, ensuring 50mm of the barrier is exposed. This allows for settlement.

4. If placing the root barrier in a 360* circle around the root ball, use Butyl tape to join each end.

5. Fill in the trench with soil, compacting the dirt.

6. Place the lawn or alternative topping back over the compacted soil trench.

7. Trim the barrier if needed to ensure it doesn’t interfere with lawn-mowers or the look of the garden. Make sure the top of the barrier is still visible.

Am I able to use a root barrier on planted, mature trees?
No. It is an effective solution before a tree becomes too mature, as the perimeter of the root system is too difficult to locate. The barrier can be installed at any time when protecting structures such as footpaths.

As well as tree roots, what other plants would benefit from root barrier installation?
It could also be used to limit the spreading of Kikuyu grass. This type of grass has aggressive growth and is considered a noxious weed in many areas.

Is there a possibility that a root barrier can harm my tree?
Yes. If it is placed too close to the tree, it can restrict the roots and inhibit growth or worse kill the plant.

Where is the material sourced from?
Our Root Barrier is Australian made. They are made from durable polymer plastic that is UV resistant and designed for the Australian climate.

Will I need to purchase the butyl tape separately?
Yes. The butyl tape is highly recommended as its pressure-sensitive and creates a moisture-resistant seal.

Does it come with a warranty?
All of our products have a 12-month manufacturer’s warranty.

On average, how long can I expect my root barrier to last?
They are made from flexible, UV stabilised High-Density Polythene and can last extremely long periods. It is a permanent solution which shouldn’t need replacing
