Clay - The ProblemThe presence of clay is viewed by pavement designers as a risk to be mitigated. Pavements constructed on expansive clay sub-grades, universally suffer from clay soil heave (which is the expansion of clays due to the ingress of water). Commonly, pavement designers address this risk with a range of techniques such as lime or cement stabilisation, sub-grade pre-wetting, the use of membranes to prevent moisture migration within the sub-grade, and additional drainage.

Clay - The SolutionTERRA-3000 transforms clay into a high-performing asset.TERRA-3000 permanently and irreversibly breaks down the capillary action of water within cohesive fines during treatment.As a consequence, treated soil particles more closely associate during compaction.

Clay - The ResultThe treated layer is no longer prone to the problems associated with the ingress of water.Pavement strength is markedly improved.

TERRA-3000® is TERRA SYSTEM’s flagship soil stabiliser.TERRA SYSTEM is the sustainable development company at the heart of the Thin Pavement Movement™.The Thin Pavement Movement™ proclaims that a single high performing base-grade can replace the multi-layered (sub-grade, sub-base, and base layers) found in traditional pavement design.TERRA-3000® facilitates the creation of a base-grade from in-situ materials at a lesser depth, delivering better performance at lower cost, than traditional pavement design.

TERRA-3000® improves the mechanical and hydraulic performance of treated soils.TERRA-3000® is a liquid concentrate that is diluted with water during treatment.TERRA-3000® permanently and irreversibly improves the performance of treated soils.

Soil colloids are the most active constituent of soil and determine the physical and chemical properties of the soil. They are very small particles which are one-thousandth of a millimetre (0.0001 mm) in size.
TERRA-3000® is a chemical product (nanotechnology) that acts as a catalyst to permanently alter the properties of soil colloids.TERRA-3000® produces an electro-physical reaction (ion exchange) in cohesive fines (clays, and silts) during treatment.
The ion exchange reduces the surface tension of water in soil colloids, so that the barrier film surrounding colloids is dispersed. As a result, the capillary action of the treated soil particles is effectively broken down.

As a consequence, treated soil particles more closely associate during compaction.TERRA-3000® is not a binding agent nor binder, however, treatment enhances the natural agglomeration of fines under compaction. TERRA-3000® produces flexible unbound pavements.
TERRA-3000® is a liquid concentrate that is diluted with water during treatment. In concentrate form it has a milky brown colour.
TERRA-3000® contains chemically engineered amine compounds and has mild ammonia odour during application.

When applied as directed to suitable candidate materials, TERRA-3000 increases the strength and density of stabilised soils and prevents the ingress of water.

Pavement construction with TERRA-3000 typically involves the application of TERRA-3000, mixing, shaping and compaction (stabilisation) of a single layer of suitable candidate material.Treatment is as simple as RIP, MIX, SHAPE and ROLL...TERRA-3000® is a liquid concentrate that is diluted with water during treatment.
The dilution rate is determined by:• NMC: The natural moisture content of the candidate material.
• OMC: The optimal moisture content for compaction of the candidate material.
• Standard Dilution Rate of TERRA-3000 is 1:20 (assuming candidate material has reached OMC).The dilution rate for your project will be detailed in your treatment plan.TERRA-3000 is typically applied from a water cart or injected by a mechanical stabiliser.

TERRA-3000® requires the presence of cohesive clay and silt fines to improve the mechanical and hydraulic performance of soil.
Whilst the majority of soil profiles commonly found in Australia are suitable for treatment with TERRA-3000, any discussion starts with our recommendations for optimal performance:
Model Particle Distribution
1. Even particle distribution range between (particle size 0.002 mm and 37.5mm).
Larger Particles
2. Larger fractions (> 50 mm) to be crushed prior to treatment.
We assist customers to determine the suitability of TERRA-3000, and support customers to commission materials testing to satisfy themselves that TERRA-3000 is suitable for each project.
A sound starting point, is to perform Particle Size Distribution/s and Hydrometer Test/s. The hydrometer test/s quantify the clay and silt fractions within the candidate materials.
TERRA-3000® is suitable and safe to use in environmentally sensitive areas such as rivers and lakes.

TERRA-3000 is subject to rigorous laboratory and in-situ performance testing on a daily basis. TERRA SYSTEM recommends in-situ testing during treatment to ensure outcomes are compliant with pavement design goals.It is the role of TERRA-SYSTEM and our Accredited Solution Partners to assist customers to decide for themselves whether TERRA-3000 is suitable for their project by supporting customers during materials and in-situ testing (pre, during and post-project).Our performance results are largely driven by the suitability of the candidate materials to be treated.

Performance is predictable based on our analysis of particle size distribution and hydrometer test results (to determine the clay/silt fraction of the candidate material).We provide guidelines in respect of the materials suitable for treatment with our products and offer customers assistance in satisfying themselves that the products are fit for purpose.Our willingness to submit our products to testing (in-situ and laboratory) day-in , day-out is what sets us apart from other proprietary solution providers.TERRA-SYSTEM and our Accredited Solution Partners train civil construction crews in the application of our products and construction methodologies.
