TerraRoads is a concentrated liquid multi-enzyme soil stabilization formula. When mixed with water and applied to existing on-site soils during road construction, it catalyses the natural bonding of soil particles — producing a denser, stronger, more water-resistant road base without cement, lime, or bitumen.

How do enzymes stabilize soil?

The enzymes in TerraRoads act as biological catalysts. They reduce the surface tension of water in the soil, allowing finer compaction and tighter particle bonding during the construction process. The result is a road base with significantly higher density, load-bearing capacity, and resistance to water infiltration than untreated soil.

What soil types does TerraRoads work with?

TerraRoads is effective across a wide range of soil classifications including clays (CL, CH), silts (ML, MH), and mixed soils (SC, SM, GC, GM). It performs best in soils with sufficient fine-particle content. Sandy or gravelly soils with very low clay content may require a soil assessment before treatment.

How is TerraRoads applied?

TerraRoads is diluted in water at the specified application rate and applied to the prepared road base using a water cart or spray system. The treated soil is then mixed, graded, and compacted using standard road construction equipment. No specialist machinery is required beyond what is already on a typical road construction site.

How long does TerraRoads treatment last?

A properly constructed TerraRoads-treated road base can last up to four times longer than an untreated road under equivalent traffic and environmental conditions. Longevity depends on correct application, adequate compaction, appropriate drainage design, and traffic loading.

How does TerraRoads compare to cement stabilization?

Cement stabilization permanently alters soil chemistry, requires significant material haulage, and carries a high embodied carbon footprint. TerraRoads uses existing on-site materials, requires no cement delivery, reduces water demand by up to 25%, and leaves no permanent chemical alteration to the soil. It is also non-toxic and biodegradable, unlike cement which raises soil pH significantly.

How does TerraRoads compare to lime stabilization?

Lime is effective on high-plasticity clays but raises soil pH dramatically, can cause alkaline leachate into groundwater, and requires careful handling due to caustic burn risk. TerraRoads is non-caustic, non-toxic, and does not alter soil pH. It is safe to handle without specialist protective equipment and poses no groundwater contamination risk.

Does TerraRoads replace cement and lime entirely?

In many applications, yes — TerraRoads can replace cement or lime stabilization entirely when the existing soil has sufficient fine-particle content and the project specifications allow for enzyme-based treatment. In some high-load or marginal-soil applications, TerraRoads may be used to reduce the quantity of cement or lime required rather than eliminate it entirely. A soil assessment will determine the appropriate approach.

Can I stabilize soil for a road without using cement?

Yes. TerraRoads is specifically designed to stabilize road bases without cement or lime. By catalysing the natural bonding of existing soil particles, it achieves CBR improvements of up to 300% and produces a road base that meets or exceeds the structural performance of cement-stabilized roads in many soil types — without any cement input.

Is TerraRoads an eco-friendly road stabilization product?

Yes. TerraRoads is non-toxic, fully biodegradable, and derived from natural organic sources. It reduces water consumption by up to 25%, eliminates the need for high-carbon inputs like cement and lime, suppresses road dust by up to 95%, and does not leach into groundwater or alter soil chemistry permanently. It is one of the most environmentally responsible road stabilization products available.

Is TerraRoads toxic to humans, animals, or the environment?

No. TerraRoads is non-toxic to humans, animals, and aquatic organisms at recommended application rates. It is fully biodegradable and classified as non-hazardous for transport and storage. It is safe for use near waterways, farms, wildlife corridors, and populated areas.

How does TerraRoads reduce water use in road construction?

TerraRoads reduces the optimum moisture content required for soil compaction by up to 25%. This means less water needs to be added to the soil to achieve maximum density during construction. On a typical 10 km rural road project, this can translate to hundreds of thousands of litres of water saved — a significant advantage in arid regions, drought-affected areas, and remote locations where water trucking is expensive.

Does TerraRoads suppress road dust?

Yes. TerraRoads-treated roads generate up to 95% less dust than untreated gravel roads. This protects surrounding vegetation from particulate coating, reduces fine-particle contamination of nearby waterways, and improves air quality for communities and workers along treated roads.

What types of roads and projects is TerraRoads suitable for?

TerraRoads is used on rural and municipal roads, mining haul roads, agricultural access tracks, airstrips, subgrade stabilization for paved roads, forestry roads, and conservation area tracks. It is suitable for any project where the existing soil can be treated in place and where improved load-bearing capacity, dust suppression, and extended service life are required.

Is TerraRoads suitable for mining haul roads?

Yes. TerraRoads is widely used on mining haul roads where dust suppression, load-bearing capacity, and reduced maintenance frequency are critical. Its ability to achieve CBR improvements of up to 300% makes it well-suited to the high-load, high-frequency traffic conditions typical of active mine sites.

Can TerraRoads be used in remote or arid locations?

Yes — and it is particularly well-suited to remote and arid environments. Its 25% water reduction benefit is especially valuable where water is scarce or expensive to transport. It requires no specialist equipment beyond standard road construction machinery, and its concentrated liquid format means it is practical to transport and store in remote locations.

Can TerraRoads be used to rehabilitate existing roads?

Yes. TerraRoads can be applied during road rehabilitation projects where the existing base material is ripped up, treated, and recompacted. This in-place recycling approach avoids the need to import new base material, significantly reducing project cost and environmental impact.

How do I get TerraRoads for my project?

TerraRoads is available through our global distributor network. Contact us with your project details — location, soil type, road length, and traffic loading — and we will connect you with the appropriate regional distributor and provide a project-specific application recommendation.

What formats and pack sizes is TerraRoads available in?

TerraRoads is available in 1 US Gallon jug, 5 US Gallon bucket, 55 US Gallon drum, and 275 Gallon tote formats to suit projects of all scales — from small rural road trials to large-scale infrastructure programmes.

How much TerraRoads do I need per kilometre of road?

Application rates vary depending on soil type, road width, and compaction depth. The standard rate is 1 litre of product per 15 m³ of material. Contact us with your project specifications for a precise application rate calculation and product quantity estimate.

Does TerraRoads provide technical support for projects?

Yes. Our team provides full technical support including soil assessment guidance, application rate calculations, construction methodology advice, and quality assurance recommendations. We work directly with project engineers, contractors, and government road agencies to ensure correct application and optimal results.
