Helping UK construction projects reduce imported aggregates, transport emissions and waste.
Discuss Your ProjectTraditional road and compound construction often relies on excavating existing soil and replacing it with imported aggregates. Ground stabilisation offers a more sustainable alternative by improving site-won soils using specialist binders such as lime, cement or GGBS.

cement required versus approx. 3,000tn imported aggregate
Requires quarrying, processing, haulage and placement of large volumes of aggregate. This creates high transport emissions, resource depletion and additional excavated waste.
Reuses site-won material, reduces imported aggregate demand and lowers vehicle movements. This supports faster construction, reduced waste and lower overall carbon impact.
| Aspect | Ground Stabilisation | Imported Aggregate |
|---|---|---|
| Material Sourcing | Site-won soils, minimal import | Quarried aggregates, significant import |
| Resource Depletion | Low | High |
| Transport Emissions | Low | High |
| Carbon Footprint | Low | Higher |
| Construction Speed | Faster | Slower |
| Waste Generation | Low | Excavated material waste |
A 1.0km haul road, 5.5m wide, requiring a 300mm sub-base would traditionally require approximately 3,000 tonnes of imported aggregate. Using a carbon intensity of 60kg CO₂ per tonne, this equates to approximately 180 tonnes of CO₂.
With ground stabilisation using 3% cement addition, the same road would require only around 90 tonnes of cement, equating to approximately 54 tonnes of CO₂.
