What is Neoloy Technology?
Neoloy Technology is a Novel Polymeric Alloy (NPA) developed to improve the strength and durability of geosynthetics’ products. It is a strong, stiff and creep resistant alloy, the only one in the market today that can guarantee geotechnical-engineering properties for up to 75 years.
Neoloy is commercially available to any geosynthetics manufacturer, interested in providing long-term warrantied performance to their products.
Why Neoloy Based Geocells?
Geocells Neoloy technology strengthens soft soil by mechanically confining the soil in three-dimensional honeycomb geometry. The geocell ability to confine soil over the long-term depends on retaining its geometry. If the geocell volume changes over time, the infill soil settles, compaction is lost and the design’s parameters invalidated. Even a change of 3% in the geocell geometry may result in a structural failure.
Upon loading geocells deform overtime as a result of the stress on the cell walls.
For example, vertical loading on geocells in load support applications, such as roads, railways, airports and ports, is transferred laterally to hoop stresses on the cell walls. This stress causes strains (deformations) which gradually accumulate over the project design life. if and when a geocell (polymer) creeps more than 3%, the change in dimensional stability will result in a loss of soil confinement and the structure may fail.
The Neoloy material in the PRS Neoloy Geocell enables a new generation of geocell, with performance properties guaranteed for the project design life:
- Elastic Stiffness (Dynamic Modulus) – maintain stiffness under dynamic loading.
- Permanent Deformation (Creep) – total accumulated elongation is <3% at the end of the design life
- Cell Tensile Strength – maintain geocell geometry under load
Neoloy Geocells – Proven Results
More than 7- academic papers were published over the last 15 years validating the effectiveness of Neoloy (NPA) geocells for soil reinforcement in roads, railways, retaining walls and other geotechnical engineering applications. As a result of this comprehensive research, Neoloy-based geocells are the only geocell with a proven engineering methodology that integrates the performance characteristics with the structural engineering requirements.

In addition, Neoloy Geocells superior performance has been proven in 1000’s of projects worldwide. Testimonials from leading engineering firms and institutes attest to the fact that the Neoloy new generation of geocells are qualified for long-term, civil engineering use under any load conditions and environment.
