Soilbond A01 is a liquid stabiliser for stronger, more durable, longer lasting natural surfaces

Key Benefits

Soilbond A01 is a liquid binder designed to increase cohesion, structural integrity and erosion resistance, delivering long‑term performance while preserving natural aesthetics.

When mixed through the material and compacted, A01 binds fine particles together to create a durable, natural-looking surface while helping reduce erosion, dust and ongoing maintenance.

Suitable for civil, landscape, council, commercial and residential applications, Soilbond A01 provides a flexible alternative to traditional stabilisation methods where maintaining the natural appearance and lifespan of granular materials is important.

Product Description & Composition

Soilbond A01 is formulated using Tall Oil Pitch (TOP), a naturally derived material produced during pine processing in the pulp and paper industry.

Tall Oil Pitch provides the binding properties that help improve cohesion within granitic sand and suitable granular materials.

When thoroughly mixed through the material and compacted, A01 helps create a robust, stabilised surface while retaining the natural granular appearance.

A01 is supplied as an easily handled liquid and is designed for uniform mixing across a wide range of civil, landscape and recreational applications.

Applications

Soilbond A01 is suitable for a wide range of applications where stabilisation of granitic sand or granular material is required. Typical applications include:

Unsealed roads and road shoulders
Driveways and access roads
Pedestrian paths and shared paths
Cycleways and bike tracks
Public realm and open spaces
Parks and recreational areas
Sportsgrounds
Playground areas
Median strips and verges
Roundabouts
Car parks
Road patching and potholes
Solar and wind farms
Residential landscape projects
Fire pits and garden areas
Granular pavements
Surfaces subject to wind or water erosion
Suitable pavement applications requiring improved surface cohesion

Suitable for projects ranging from large-scale civil, infrastructure, council and government works through to commercial and residential installations.

Material suitability can vary depending on grading, particle size distribution, fines content, location and the intended application. Contact our team for advice on materials not listed above or before commencing larger projects.

Coverage & Application Rates

Standard Application Rate
Soilbond A01 is generally added at a rate of:
2% of the dry weight of the material being treated

For a treatment depth of 50 mm, this equates to approximately:
2 litres of Soilbond A01 per m²

A standard 2% application rate is suitable for most installations.

Refer to the Stabilisation Coverage Table for more information.

Higher Application Rates
Increasing the application rate to 3% may be considered where additional surface binding is required. This may further reduce loose fines and reduce permeability.

Where pavements are subject to particular site conditions, including slopes of 5 degrees (approximately 1:12) or greater, contact us for project specific advice.

Application rates may be adjusted depending on:

Material grading and fines content
Required surface performance
Traffic loading
Moisture conditions
Site conditions
Surface gradient

Installation & Application

Soilbond A01 must be diluted with water and thoroughly mixed through the granular material before final compaction.

Application is required by one of the following methods:

1. Stockpile Mixing
This is the preferred method where practical.

Soilbond A01 is mixed through the granular material using suitable mechanical equipment, such as a:

Bobcat
Front-end loader
Backhoe
Excavator
Cement mixer or other suitable mechanical mixing equipment
Your preferred landscape supplier may be able to assist

The treated material is then placed, levelled and compacted.

2. In-Situ Application
The existing surface is scarified to the required treatment depth, we recommend a minimum 50 mm compacted depth.

Soilbond A01 is then distributed through the loosened material and thoroughly mixed before levelling and compaction.

Suitable application equipment may include spray equipment, hoses or other methods that provide event distribution and are appropriate to the project size and site conditions.

Compaction
Adequate mixing and compaction are essential to achieving a consistent treated surface.

Compaction may be carried out using suitable equipment such as:
