Neoloy Tough-Cells: Sustainable Road Solutions for Unpaved Gravel Roads
Neoloy is a more sustainable, cost-effective and long-term solution for unpaved roads more than any other geocell, geogrid or ground reinforcement method.
Key Challenge:
Although 80% of the world’s roads are unpaved, millions of people rely upon them for access, services and resources. However, these roads often face multiple challenges – soft soils, insufficient aggregate, maintenance and drainage, as well as accelerated rutting and degradation. That’s where you need an innovative, sustainable solution like Neoloy.
The Neoloy Tough-Cells Solution
Neoloy Tough-Cells are a sustainable geocell road solution for unpaved, gravel and low-volume roads. Neoloy Tough-Cell stabilization stabilizes soft subgrades and reinforces the unbound base of all types of unpaved roads: access roads, haul roads, gravel roads as well as rural, low volume or temporary roads.
Made of Novel Polymeric Alloy (NPA) the rigid Neoloy Tough-Cells offer the following benefits:
- Soil bearing capacity – improve by 7.6x
- Sustainable – improve locally available, marginal quality soils for infill
- Fast construction – reduce pavement layer thickness by 75%
- Extended lifespan – more traffic for up to 10x longer service life
- Low maintenance – low rutting means without frequent addition of gravel/regrading
Why Neoloy
The unique Novel Polymeric Alloy (NPA) adds high stiffness (>500 MPa @ 60°C) to Neoloy®. This creates a semi-rigid slab or beam effect, which improves layer modulus up to 500%, verified in Accelerated Pavement Testing (APT). The improved pavement stiffness and durability reduce rutting and surface deterioration. Wear and tear on vehicles are decreased as are road repairs and maintenance. Neoloy makes unpaved roads over challenging terrain safer, more reliable and sustainable.
Neoloy Tough-Cells’ unique reinforcement factors also enable marginal quality materials for infill as well as up to 75% thinner pavement layers. Locally available, partially cohesive, recycled and granular materials can be used as structural fill, instead of expensive imported aggregate. These translate into considerable savings in construction time and costs as well as lower carbon footprints.
The Neoloy Tough-Cells solution is proven worldwide for easy logistics, all-weather construction in extreme climates/conditions, durable use and a longer service life. Unpaved roads constructed with Neoloy Tough-Cells are more sustainable and economic with a lower total life cycle cost.

- Large increase in bearing capacity due to validated improvement factors
- Lower construction costs and time – reduce pavement thickness up to 70%
- Green/sustainable solution – uses inferior/recycled materials for structural infill
- Resilient solution extends service life
- Reduce settlement, rutting and maintenance
- All weather construction and all-weather use
- Reduce aggregate, hauling and placement costs for unpaved roads
- Reduce unpaved road repairs, long-term maintenance, operating costs
- Lower initial unpaved road construction costs and Total Cost of Ownership
- Use of marginal and recycled infill reduces quarrying, hauling and carbon pollution
- Reduce road dust and sedimentation – low environmental footprint
- Self-draining system for reliable year-round transportation
Unpaved Road Solutions
Neoloy Tough-Cell geocells are suitable for all types of low volume unpaved access roads construction, such as:
- Access roads for transporting heavy equipment and vehicles to remote oil rig sites
- Haul roads for natural resources, mining and forestry logging operations
- Service roads for transportation, energy sector, pipeline and utilities maintenance
- Rural roads for remote areas and developing regions (laterite or murram soil ‘dirt’ roads)
- Military roads for reliable, secure roads for heavy vehicles in hostile environments
- Green roads for intermittent trafficking over grass shoulders, parking lots and low impact development
- Temporary roads for access to drilling sites or for bypass roads in road construction projects
Unmatched by other ground improvement solutions (e.g., chemical stabilizers, geotextiles, geogrids, access mats), Neoloy Tough-Cells unpaved road, access road, and haul roads reinforcement consistently exceed customer expectations.
