Ultra-tough root barrier that lasts

Our Root Growth Inhibitors are bentonite barriers that repel tree roots. They keep your path or driveway level by shielding it from thirsty roots and stabilising the surrounding soil.

How our Tree Root Inhibitor works

Trees and shrubs suck up large amounts of water from soil. When the soil becomes dry, pressure is created which causes it to move towards moister nearby soil (a process known as matric suction). This soil movement can easily damage paths, driveways and pipes, which are expensive to fix.

Our Root Growth Inhibitors have a pH level that is unsavoury to tree roots, which causes them to avoid the compound and find moisture elsewhere. By adding a layer of Root Growth Inhibitor under your path or around your pipe, there’ll be no roots to disturb the soil, which keeps it nice and secure.

Root Barrier Uses

Stabilise paths, driveways, and pipes

Our Root Growth Inhibitors repel roots, which helps to control soil moisture around paths and pipes and stabilises them

Double the life expectancy of paths and driveways

With reactive soils stabilised, your paths will last for much longer

Reduce maintenance

By adding our root growth inhibitors underneath paths, driveways, or around pipes, you can avoid time-consuming, expensive repairs

Stabilise paths against wandering tree roots and reactive soils

Pipe Trench Inhibitor
Prevent pipes from moving, and keep them connected

Tightly-controlled soil moisture

Australian plants are incredibly thirsty, and when combined with reactive soil, can cause substantial damage to buildings and other infrastructure. Our barrier protects against matric suction and reactive clay soil, by preventing roots and moisture from ever reaching them.

Plenty of stock, cut to your specifications

We keep plenty of flexible root barrier in our warehouse, which is cut to custom lengths and delivered to you fast.

100% natural

Our Root Growth Inhibitors are made from sodium bentonite and 100% natural (no nasty extra chemicals). They’re essentially the same salinity as sea water, which repels tree roots.
Combine with Root Barrier membrane for extra protection

Combine our Root Growth Inhibitor and Root Barrier membrane to create an impenetrable wall against tree roots, guaranteed to protect important infrastructure.
Plant trees closer to paths

When used in combination with our Root Barrier membrane, our bentonite root barrier allows you to plant trees close to paths, without worrying about future damage. Public paths will remain flat and smooth, without a crack in sight.
Keep public pathways safe

By ensuring that public pathways are flat and smooth, you can prevent people from tripping or falling over.

Easy to install

Our Root Growth Inhibitors are easy to install and we provide full installation guides for a range of scenarios.
