Soil Bond

Soilbond A01 stabiliser / binder is a naturally derived binder suited for granitic sand materials and an ideal alternative to cement stabilisation as it’s made from natural materials. It’s a liquid emulsion that needs to be worked through the materials before compaction. It’s not a topically applied / spray on the compacted surface product. After compaction, it will provide stabilised material and a robust & durable surface, with a natural looking finish.

Please keep in mind that Soilbond is not a sealer, therefore the finished surface will still have fine loose particles that can be swept, but will not be eliminated.

Soilbond is an environmentally friendly, non-hazardous, non-dust, alternative to cement stabilisation and chemical products.

Soilbond offers the following benefits:

• Greater structural integrity, particularly under wet conditions
• Resistance to wind and water erosion
• It doesn’t leach over time
• Increases surface life
• Reductions in maintenance costs
• Provides a robust & durable surface
• Assists in reducing dust levels
• Maintains a natural look
• Easy and safe to install
• Premix or insitu apply
• Surface is trafficable straightaway
• Non-hazardous, environmentally friendly product and an ideal alternative to cement stabilization
• Australian made – we are the manufacturer

Materials suitable for Soilbond:

• Soilbond will bind with granitic sand materials including: decomposed granite, crushed limestone, gravel fines, toppings, crushed rock, sandstone, crushed bricks, crusher dust and recycled materials. For anything else, please let me know.
• There needs to be some fines/stones in the material up to a maximum of 20mm
• It’s not suitable for clean aggregates as there’s nothing to bind to
• Soilbond needs PI or clay to bind to – this is critical

Application rate:

• Standard application rate of 2% suits most installations
• Increasing the application rate to 3% will reduce the amount of loose fines on the surface and permeability
• When working with a slope / grade of 5 degrees or more we recommend lifting the application rate to 3%

Application Methods:

Soilbond A01 stabiliser / binder requires application as follows:

1. stockpile / premixing; OR
2. In situ application

• Mixing of Soilbond with the Granitic Material prior to laying is preferable, otherwise you need to scarify the top 50mm minimum (or as specified) & mix in the Soilbond then compact using a roller / wacker.  We recommend a minimum of 50mm Compacted Depth at 2% per Tonne of Soilbond.  Soilbond can be applied using a watering can or hose to spray over the area that has been scarified. It then requires levelling / compacting.
• Stockpile / premixing – this can be done with a bobcat, backhoe, excavator, cement mixer, basically any mechanical aid. If premixing material – it will need to be used within 24 – 48 hours max. Check OMC before compaction.

The critical points for a successful installation are:

• Using a granitic sand material that will effectively bind with Soilbond
• Ensuring Soilbond is uniformly mixed into the materials to achieve Optimum Moisture Content (clench test)
  • if this is not achieved and the material is too dry prior to compaction, this can result in excess loose fines
• Properly compacted with a roller / wacker
• Once this is achieved the end result will see stabilised material with a robust and durable surface and a natural looking finish
