Stabilise foundations. Conquer cracks

Our foundation barrier allows you to tightly control soil moisture under your building, preventing movement.

Tell us about your project

Installation can be certified by structural engineers

When correctly installed, our Root Barrier™ offers guaranteed root protection and is trusted by arborists, builders and engineers.

Foundation Barrier Uses

Control moisture for clay soil

Control moisture levels for reactive soils to stabilise them and prevent building structure movement

Building code compliant

Be compliant with standard building codes and be sure that the property is on stable soil

Avoid costly repairs

Our foundation barrier prevents property movement, so you won’t need to spend thousands of dollars repairing cracks, or underpinning footings

The widest barriers on the market

Our deep root barriers can be cut to two metres or greater, to protect against large trees

Lightweight and extra-strong

Our 0.75mm product is made of high density polyethylene and virgin resin, to create a light, high-strength barrier

Highly stretchable

700% elongation, allowing the product to stretch to a huge degree without breaking

Stop bank-busting house damage

When correctly installed, our Root Barrier™ offers guaranteed root protection, and is trusted by arborists, builders and structural engineers.
Structural engineers will oversee the installation of the root barrier, to help protect your property from soil-shifting trees that can take litres of water from the earth everyday. By placing the root barrier in the optimal spot, the barrier stops roots in their tracks and diverts them away from your home, where they can raise or lower the ground without causing bank-busting foundational damage.
Structural engineers trust in the innovative technology of Root Barrier™—It’s the number one way to protect your property from roving tree roots and is the original root barrier that gets the job done.

How our Foundation Barrier works

Trees and shrubs suck up large amounts of water from the soil. When the soil becomes dry, equalising pressure is created which causes moisture to move to nearby dryer soil (a process known as matric suction). Matric Suction causes subsidence in the foundation soils and when a property is built on top of this land, its foundations become unstable often subsiding causing cracks to appear in the property’s concrete slab including walls and the repair bill can be thousands of dollars.

By eliminating the tee effect and its matric suction forces and or controlling soil moisture levels. Our Foundation Barrier controls its moisture content, which stabilises it and keeps the property on level ground.

Easy to install

Our barrier is straightforward to install and we have clear installation guides for various scenarios.

Complete protection for foundations

Complete two-part package that fully protects foundations against shifting reactive soils:

1) Root barrier membrane

These products can be used separately, depending on your needs. We can recommend a solution for you.

Avoid expensive cut-off walls

Shifting soils are often prevented by constructing an underground cut-off wall between the property and the tree, made from reinforced concrete or steel sheet piling. This is expensive, time-consuming and fails if the concrete cracks, allowing roots to weave their way through.

Our foundation barrier doesn’t suffer from these problems. It’s made from super-strength high density polyethylene which has 700% elongation. Even the biggest and most motivated tree roots are unlikely to break through.
