How Geocells Assist in Unpaved Roads

How Geocells Reinforce Unpaved Road Bases

Unpaved roads are common across South Africa, but anyone who works with them knows they can be tricky. Soft soils, heavy trucks, erosion, and constant repairs make life difficult for engineers, contractors, and drivers. Roads without proper support quickly develop ruts, potholes, and uneven surfaces, which adds maintenance work and slows traffic. PRS Geo‑Technologies has a solution that works in practice: Neoloy® Tough-Cells. These geocells stabilise roads, make them safer, and help them last longer. They also reduce costs and have a lower environmental impact than traditional solutions.

What Are Geocells?

Geocells are three-dimensional honeycomb structures made from a strong polymer. Laid over a prepared roadbed and filled with gravel, soil, or crushed stone, they trap the material in place. The weight of vehicles spreads evenly across the surface, stopping ruts and uneven patches from forming, even under heavy traffic. Compared with traditional methods like thick gravel layers, cement stabilisation, or standard HDPE geocells, Neoloy® Tough-Cells are tougher, flexible, and easier to work with. They’re UV-resistant and handle chemical exposure, which makes them reliable in mining, industrial, or rural areas.

Stabilising Weak and Unstable Soils

Soft or loose soil is a big problem for unpaved roads. Heavy trucks or farm vehicles can sink into the surface and create deep ruts. Geocells hold the soil inside the honeycomb, making it stronger and more stable. You’ll see this working really well on mining haul roads, rural tracks, or anywhere heavy vehicles run regularly. Even after rain, the surface stays firm, which is what you want. The cells prevent lateral soil movement, which is usually the main cause of road failure. That means fewer potholes and a surface that vehicles can actually use safely.

Improving Safety and Traction

Unpaved roads can get slippery, especially after rain. Drivers know the struggle tyres spinning, vehicles sliding, potholes popping up. Geocells help by keeping the surface firm and spreading the load evenly. Cars, trucks, and machinery get better grip, and accidents happen less often. Municipal roads, industrial access routes, and rural tracks all benefit. Engineers often notice that traffic flows much smoother when geocells are in place, and vehicles don’t suffer as much wear and tear.

Extending Lifespan and Reducing Maintenance

Most unpaved roads need constant attention. Gravel washes away, ruts form, and surfaces degrade quickly. Geocells stop that from happening because they hold the infill in place. Roads last longer, and repairs are needed less often, which is especially useful for remote areas where getting machinery in is tricky. Mining haul roads, farm tracks, and industrial access routes benefit most. Roads stabilised with geocells hold up better over time, saving contractors and municipalities a lot of headaches.

Cost-Effective and Sustainable

Geocells allow engineers to use thinner layers of gravel or even recycled soil without losing performance. That reduces material costs, transport, and environmental impact. Using Neoloy® Tough-Cells also lowers the need for virgin aggregates, which is a bonus if you care about sustainability. Roads go in faster but still handle heavy traffic reliably. It’s a practical way to save money while doing something better for the environment.

Installation Made Simple

Installing geocells is simpler than most people think. First, the roadbed is prepared. Then the cells are laid out, expanded, and filled with gravel or soil. After compaction, the road is ready for traffic. You don’t need much heavy equipment, and trained staff can get the job done quickly. Even in remote areas, geocells can be deployed efficiently. In practice, it’s a smooth process that consistently delivers good results without overcomplicating things.

Geocells are a practical and proven solution across a wide range of infrastructure applications, including unpaved roads. By stabilising weak soils, improving load distribution and traction, and extending service life, geocells significantly reduce maintenance demands. PRS Geo-Technologies supplies Neoloy® Tough-Cells, supported by expert design services and performance guarantees, making them suitable for many geocell applications in road construction. Engineers, contractors, municipalities and industrial developers can rely on geocells to address common road challenges while saving time, cost and resources. From rural access routes to mining haul roads and industrial roads, geocells remain a smart, long-term investment for stronger, safer and more reliable infrastructure.
