Neoloy optimizes the use of geocells in highway engineering for engineers and contractors by providing design assistance as well as by a choice of categories of geocells customized to project requirements. The result? Increased performance at lower cost, no matter the project type.

  • New design methods – integrating the Neoloy Geocell modulus improvement factor (MIF) for use in unpaved roads (Giroud and Han method) and paved roads (layered elastic model method)
  • New specifications and standards – performance based specs that more accurately reflect the performance of geocells in the field than conventional specifications.
  • Engineering consulting – PRS provides geotechnical engineering and design services to maximize the impact of Neoloy Geocells in each highway project.
  • New Neoloy categories – PRS developed 4 main types of geocells to optimize a project (and cost-effectiveness) by matching the tensile strength and durability of Neoloy Geocells to the project requirements.



  • Confinement increases layer strength (modulus)
  • Reinforcement reduces layer thickness and wearing course
  • Beam effect improves load transfer and bearing capacity
  • Modulus Improvement Factor (MIF) allows more traffic and for longer time
  • More reinforcement than any geogrid


  • Simple logistics and fast all-weather installation
  • Lower construction, infill costs
  • Improve pavement lifespan
  • Reduce repairs, maintenance cycles and downtime


  • Use locally available, ungraded or recycled materials for infill
  • Reduce quarrying, hauling, fuel, pollution, carbon footprint
  • Green sustainable construction method

Novel Neoloy Polymer Alloy

  • Provides very high stiffness, dimensional stability, creep resistance
  • Long-term performance under heavy dynamic loading
  • Outperforms any other HDPE geocell
