Where TerraRoads performs

Applications across every terrain and industry

From remote mining haul roads to municipal streets and agricultural tracks, TerraRoads natural enzyme stabilization adapts to the project — not the other way around.

Use cases

Rural & low-volume roads

Unpaved rural roads are the most common application for TerraRoads. Enzyme treatment converts native subgrade and base course material into a stable, all-weather surface without importing aggregate.

  • Eliminates seasonal softening and rutting
  • Reduces grading frequency by up to 80%
  • Suitable for all-weather access in remote areas
  • Works with existing native material — no aggregate import required

Project example

A 42 km rural access road in a semi-arid region was treated with TerraRoads at a rate of 1 litre per 15 m³ of material. Post-treatment CBR testing showed a 280% improvement in bearing capacity. The road has required zero re-grading in 36 months of operation under daily light vehicle and weekly heavy vehicle traffic.

Mining & haul roads

High-axle-load haul roads demand exceptional bearing capacity and dust control. TerraRoads delivers both, reducing the water-cart cycles required for dust suppression and extending the service life of compacted haul surfaces.

  • Supports heavy axle loads without surface deformation
  • Dramatically reduces water-cart operating costs
  • Improves visibility and air quality for site workers
  • Compatible with standard mine road construction equipment

Project example

A copper mine in a high-altitude arid environment treated 18 km of primary haul road. Water-cart frequency dropped by 70% in the first season. Independent dust monitoring confirmed a 92% reduction in PM10 particulate levels at the road edge, meeting the site's environmental compliance targets.

Agricultural tracks & farm roads

Farm tracks carry heavy harvesting equipment and must remain passable through wet seasons. TerraRoads stabilizes the subgrade so tracks stay firm under loaded grain trucks and combine harvesters without the cost of sealed pavement.

  • Maintains access during and after rainfall events
  • Prevents crop loss from inaccessible paddock tracks
  • Non-toxic — safe for surrounding soil, crops, and waterways
  • Low application cost relative to gravel or sealed alternatives

Project example

A grain farming operation treated 8 km of internal paddock tracks before the harvest season. The tracks remained passable through three significant rainfall events that had previously caused harvest delays. The farmer reported zero lost harvesting days compared to an average of four per season in prior years.

Subgrade stabilization for paved roads

Treating the subgrade beneath a paved road with TerraRoads increases the structural capacity of the pavement section, allowing thinner asphalt or concrete layers — reducing material costs and construction time.

  • Increases subgrade CBR, enabling thinner pavement design
  • Reduces asphalt or concrete material quantities
  • Extends overall pavement service life
  • Compatible with standard pavement design methods (AASHTO, Austroads)

Project example

A municipal road rehabilitation project used TerraRoads subgrade treatment to justify a 40 mm reduction in asphalt overlay thickness across 3.2 km of residential street. The saving in asphalt material offset the cost of enzyme treatment by a factor of 3.4, with the treated subgrade achieving a post-compaction CBR of 22 versus 6 untreated.

Dust suppression & airstrip surfaces

Unsealed airstrips and high-traffic unpaved areas generate fugitive dust that impairs visibility, damages equipment, and creates health and environmental compliance issues. TerraRoads binds surface fines permanently.

  • Eliminates fugitive dust from unsealed surfaces
  • Suitable for remote airstrips and helipads
  • Meets environmental dust compliance requirements
  • Single application provides season-long suppression

Project example

A remote pastoral station airstrip was treated with TerraRoads at a 1:300 water dilution for dust suppression. Post-treatment dust monitoring showed a 95% reduction in visible dust during aircraft operations. The strip surface remained stable and dust-free through a full dry season without re-treatment.

Forestry & conservation access roads

Forestry operations require temporary access roads that must be rehabilitated after use. TerraRoads provides the necessary load-bearing capacity during operations while remaining biodegradable and environmentally benign.

  • Provides temporary high-capacity access for heavy logging equipment
  • Biodegradable — no long-term environmental residue
  • Approved for use in environmentally sensitive areas
  • Reduces erosion and sediment runoff from access tracks

Project example

A forestry contractor used TerraRoads to stabilize 6 km of temporary haul road through a sensitive catchment area. The treated road carried fully loaded log trucks through a wet season without rutting or erosion. Post-harvest environmental inspection confirmed no detectable enzyme residue in adjacent waterway sediment samples.
