Proven Design Methodology Validated by Field Tests, Published Research, International Standards

Neoloy® is revolutionizing the use of geocells for engineers and contractors. How? Because the rigid Neoloy® Tough-Cells are manufactured in several different categories according to strength and other design factors. Now you can select the Neoloy type that fits the project requirements. The result is best suited performance at optimal cost, no matter which project type. PRS offers:

  • Established design methods – Extensive R&D with Neoloy included calibration of design methods for use in unpaved roads (modified Giroud and Han method) and paved roads (layered elastic model method) integrating the Neoloy Tough-Cells factors (modulus improvement factor (MIF).
  • New specifications and standards – PRS developed new performance based specs that align with the requirements of international standards and accurately reflect the performance of rigid geocells in the field than older methods.
  • Engineering consulting – as an engineering and technology company, PRS provides geotechnical engineering and design services to you maximize the cost-effectiveness of Neoloy in each project.
  • New Neoloy categories – PRS developed three categories of Tough-Cells according to the application type. This enables optimization of the geocell by matching the tensile strength and durability of Neoloy to the project requirements.


While developing a Neoloy®-based geocell unlike any other, PRS also set a new range of standards to measure the its performance, a...(Read More)
