Neoloy® Tough-Cells haul road reinforcement keeps heavy haul trucks moving over the weakest soils in all-weather conditions.
Haul roads and haul trucks are the lifeline of mining and natural resource extraction industries. That’s why Neoloy (Tough Cell) Geocells designed for heavy duty pavements can keep your mining haul trucks rolling with soil stabilization and reinforced haul road bases – even in rainy seasons and freeze-thaw cycles.
With the highest stiffness, elastic modulus and tensile strength of any geocell, Neoloy Geocells can help haul roads handle the heaviest of loads in soft soils using sand for structural infill (650+ ton payload). This is due to the high-modulus of Neoloy®-based geocells and the beam effect that it creates. Neoloy Geocell soil confinement locks soil aggregate and binds soil particles, providing strong surface adhesion and reducing fugitive dust. Neoloy reinforced haul roads resist cuts, impacts and degradation. The result is less wear and tear to tires and vehicles, and more efficient, safe and economic operations for haul roads, mine operators and natural resource extraction. Neoloy reinforced haul roads for mining provide a durable road for year-long operations
The result – Neoloy stabilized haul roads reduce maintenance and increase mine productivity.
How does it work? Neoloy Geocells increase the bearing capacity of soft subgrade and the road base modulus. Mechanical confinement locks aggregate and binds soil particles, providing shear resistance and increased stiffness. (Read more about Neoloy technology here.) The stronger foundation creates a stable road surface that improves fuel economy and ride comfort while reducing fugitive dust.
Neoloy Tough-Cells reinforced haul roads resist cuts, impacts and degradation. The result is less wear and tear to tires and vehicles, and more efficient, safe and economic operations for mining operators.
Neoloy Geocells integrated with geomembranes creates impermeable, non-slip and durable impoundment for mine waste containment and treatment using one of the following infill types:
To stabilize surface cuts or prevent erosion in water channel diversions in mining, Neoloy Geocell retaining walls maintain structural stability, even in wet, compressible and unstable subgrades and offer the following advantages:
To reinforce steep slopes of surface mines and dry waste stacks, Neoloy confines, reinforces and restrains soil and stone infill, which prevents downslope movement from hydrodynamic and gravitational forces. The Neoloy Geocell solution:
Neoloy Geocells are perfect for sustainable rehabilitation of dry and denuded mine slopes. Its unique frictional resistance, soil-cell interlock and wall strength will keep soil infill and vegetation in place, long after the mine is closed. The Neoloy solution:
In addition the same Neoloy soil reinforcement solution can be utilized for unpaved access roads, railways and storage areas and to stabilize slopes, embankments, containment ponds and mine waste heaps and for mine site rehabilitation.
Neoloy stabilizes earth, prevents erosion, allows drainage, enables root-soil interlock, protects plantings and makes landscape rehabilitation effective.
If your mine or abandoned sites need mitigation and rehabilitation, the Neoloy Tough-Cell solution helps you restore natural landscapes by stabilizing re-engineered slopes, protecting containment liners and facilitating revegetation.
The Neoloy Tough-Cell slope protection solutions are installed on eroded slopes, waste stacks or non-permeable membranes. The geocells confine soil, stabilize the slope and prevent erosion. Infilled with topsoil, the Neoloy Tough-Cells are ideal for plants. They mechanically protect plants from runoff, enable drainage, encourage plant growth and root-soil interlock and facilitate the restoration of a natural landscape.
See an example of mine waste stacks rehabilitated to a recreational park in Poland here and rehabilitation of a mine site to an ecotourism visitors center in Mexico here.
Neoloy Tough-Cells are impervious to chemicals, corrosion, acidity and extreme temperatures. When integrated with geomembranes, Neoloy also creates impermeable, non-slip and durable impoundment for mining waste containment and treatment.

Neoloy Tough-Cell surface infill options for site rehabilitation:
To reinforce steep slopes of surface mines and dry waste stacks, Neoloy Tough-Cells confine, reinforce and restrain soil and stone infill, which prevents downslope movement from hydrodynamic and gravitational forces. The Neoloy solution:
Neoloy Tough-Cells protect geoliners and containment membranes while stabilizing slopes and berms of reservoirs and landfills. It holds infill material in place and prevents mass movements by providing tensile reinforcement. The Neoloy Tough-Cell solution:
To stabilize surface cuts or prevent erosion in water channel diversions in mining, Neoloy Tough-Cell retaining walls maintain structural stability, even in wet, compressible and unstable subgrades and offer the following advantages:
Neoloy® Geocells provide reliable long-term protection of geoliners in mine tailings storage facilities, slurry pits & sludge containment ponds.
Neoloy Geocells combined with geomembranes create impermeable, non-slip and durable impoundment for mining waste liquids, leachate, slurry, sludge or tailings.
The Neoloy Geocells protect geomembranes and geoliners while stabilizing mining waste containment and treatment ponds. Neoloy holds slope infill material in place and prevents mass movement by providing tensile reinforcement. Typically filled with concrete, Neoloy shields the liners from natural, accidental or intentional damage.
Neoloy Geocells are also used for ground stabilization of the containment pond beds. They increase the bearing capacity and limit differential settlements that can stretch and damage the liners. (See a case study here.)
Mining and energy concerns in South Africa and around the world have used Neoloy Geocells for safe and reliable environmental protection and waste management. See a case study here and a published paper validating the solution here.
The durable Neoloy novel polymeric alloy (NPA) is highly resistant to liquids, chemicals, UV, oxidation and extreme temperatures for reliable long-term impoundment.
