Geocells for roads are widely used to improve road stabilization, reinforce weak subgrades and reduce pavement deterioration. However, heavy-duty roads and highways exposed to repeated traffic loading require more than basic cellular confinement.
Neoloy® Tough-Cells are advanced structural geocells engineered for long-term road reinforcement under demanding infrastructure conditions. With high stiffness, creep resistance and dimensional stability, Neoloy improves pavement performance, reduces settlements and extends road service life while lowering construction and maintenance costs.
Neoloy Tough-Cells are proven sustainable tough cells technology for paved roads that do more with less – the highest pavement performance, lowest environmental impact and lowest project costs.
Based on the unique Novel Polymeric Alloy (NPA) properties, Neoloy Tough-Cells add high elastic stiffness (>525 MPa) and tensile strength (>17 kN/m) at low deformation (<3%) to any pavement layer as specified in ASTM, ISO and other global standards. Using verified improvement factors, Neoloy Tough-Cells improve soil load bearing capacity by >7x and layer modulus by 2-5x to limit settlement and rutting up to 80% and reduce surface degradation more than conventional paved roads or other geosynthetics.
The Neoloy highest performance is achieved with 50% lower carbon footprint and environmental impacts from road construction. Design optimization reduces layer thickness up to 70% while enabling the use of marginal or recycled materials for infill. The use of finite aggregate resources is reduced as are the energy and emissions associated with production, hauling and placement. In addition to faster construction and lower costs, Neoloy Tough-Cells also extends the pavement lifespan that reduces lifecycle costs for repairs and maintenance.
Standard geocells are commonly used for road stabilization and load support applications. However, roads and highways constructed over weak subgrades or exposed to repeated heavy traffic loads require long-term structural performance beyond basic confinement.
Under continuous dynamic loading conditions, pavement systems depend on stiffness, dimensional stability and resistance to deformation to maintain long-term performance. Conventional HDPE geocells may be sufficient for light-duty or temporary applications, but demanding transportation infrastructure increasingly requires advanced structural geocells engineered for long-term reinforcement.
Neoloy® Tough-Cells were specifically developed for these challenging conditions, providing high stiffness, creep resistance and long-term reinforcement performance for roads, highways and other heavy-duty infrastructure applications.
Yes. Geocell reinforcement improves structural performance, allowing a reduction in
aggregate thickness while maintaining or enhancing load-bearing capacity.
Geocell systems can reduce aggregate use by approximately 30%–70%, depending
on soil conditions and design.
Yes. High-performance systems such as Neoloy® Tough-Cells are designed to
withstand heavy traffic loads, including trucks and industrial vehicles.
Geocells are effective in weak clay soils, sandy soils, low CBR subgrades and areas
prone to settlement.
