Neoloy® is revolutionizing the use of geocells for engineers and contractors. How? Because the high-strength of Neoloy® Geocells is 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 increased performance at lower cost, no matter which project type. PRS offers:

  • New 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 Geocell modulus improvement factor (MIF).
  • New specifications and standards – PRS developed new performance based specs that more accurately reflect the performance of geocells in the field than traditional methods.
  • Engineering consulting – as an engineering and technology company, PRS provides geotechnical engineering and design services to you maximize the effectiveness of Neoloy in each project.
  • New Neoloy categories – PRS developed four main types of geocells for each general application category. This enables optimization of the geocell (and maximizes cost-effectiveness) 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)


Customized Design with Neoloy Geocell

One shoe doesn’t fit all. Neither does one geocell fit all projects. PRS enables you to customize your geocell to fit the project ...(Read More)
