Neoloy® Tough-Cells Technology Make Gravel Roads Stronger & Sustainable
If you are building a gravel road over soft clay, sand or peat soils – Neoloy Tough-Cells offer a proven solution.
Neoloy Tough-Cells are an ideal for road construction solution for soft, problematic soils. Neoloy is an innovative geoengineering technology example that improves gravel or paved road construction, increases sustainability and reduces costs – particularly in problematic soils, difficult locations and where aggregate resources are limited.
If you have a pavement design or gravel road over soft ground with clay, sand or peat bogs, or high-water tables, Neoloy Tough-Cells offers a unique, validated and supported solution:
Road Reinforcement for Soft Clay
Neoloy Tough-Cell reinforcement of gravel roads over soft clay soils creates a beam effect over the problematic subgrade. This results in a layer that essentially ‘floats’ over the clay layer, minimizes the effects of heaving (Read more)
Road Reinforcement for Sandy Soils
The 3D confinement of Neoloy Tough-Cells enables the use of non-cohesive sand for structural infill in gravel roads. NPA based Neoloy increases the bearing capacity and elastic modulus of the reinforced sand by providing confinement to the infill material. (Read more)
Road Reinforcement for Saturated Peat
Neoloy Tough-Cells confine, stabilize and reinforce granular material in saturated peat soil. Neoloy unique improvement factors increase the modulus of the layer and distribute vertically stresses laterally. The result is a stiff layer that increases bearing capacity and decreases differential settlement. (Read more)
The unique improvement factors and engineering properties of NPA based Neoloy Tough-Cells enable all-weather, durable use and extended service life. Neoloy reduces repairs, increases maintenance cycles and saves maintenance budgets. Roads, Rails, Ports and other pavements constructed with Neoloy Tough-Cells are more sustainable and economic with a lower total life-cycle cost.
Alternative cement and chemical stabilizers are complicated and time-consuming to apply while their long-term effectiveness is unreliable. In addition, stabilizers are often affected by rain and water, as any cracks provide entry for water and eventual weakening of a gravel road base.

Benefits
- Improve bearing capacity of soft soils (reduce vertical stress by 50%)
- Modulus improvement factor enables reduction of layer thickness x3
- Improve gravel road durability and lifespan in all climates and temperature
- Confinement protects soil integrity preventing movement of infill
- Use available local borrow pits even with marginal infill to reduce gravel layers – saves money, time and resources
- Lower gravel road construction costs for limited budgets and maintenance cycles
- Self-draining system protects the gravel road base and prevents accumulation of surface water for reliable year-round transportation
- Use of local soils reduces need to import gravel aggregate
- Sufficient long-term durability to serve the rural communities throughout rainy seasons, without degradation and repairs.
