Who We Are
PRS Geo–Technologies® is a global geotechnical engineering company that helps pave a greener future. For more than 25 years, PRS combines advanced cellular confinement technology with proven engineering expertise to implement solutions for load support, slope and channel protection, earth retention and landfill and reservoir applications worldwide.
The very heart of our technology is a rigid and durable cellular confinement system for soil stabilization, Neoloy® Tough-Cells. With PRS Neoloy Tough-Cell solutions you can build better pavements, over any soil, while saving costs and time required for your project.
We believe advanced technologies should be green — this is why our solution is based on utilizing marginal land, soils and recycled materials. Neoloy needs less asphalt and less aggregate while utilizing locally available soil for structural infill. This makes our advanced cellular confinement technology highly sustainable.
In thousands of successful projects, implemented in 80 countries worldwide and validated by more than 100 published papers – PRS has proved that in the 21st century we can leverage advanced technology to build a more sustainable future. Pave better roads with less resources and time.
Our Story – New Generation of Cellular Confinement Systems
History… Although ancient cultures used soil improvement techniques, for example using branches to create access roads over swamps, the basic geocells were developed in the late 1970’s by the United States Army Corps of Engineers to land heavy military equipment on sandy beaches. The first geocells were made of cardboard, cloth, aluminum and eventually polymer plastic.
Commercial use… In the 1980’s geocells made from High Density Polyethylene (HDPE) were applied to commercial applications. Over time leading engineers and engineering companies realized these HDPE “soft-cells” were lacking engineering properties and design methodologies required for long term use in load support or other permanent use applications.
The new generation… With the emergence of advanced polymer technologies, PRS embarked an extensive R&D program with world renowned geotechnical experts and institutions to develop a Novel Polymer Alloy (NPA), which was used to manufacture Neoloy® ‘Tough-Cells’. Neoloy Tough-Cells provide superior engineering properties – high elastic stiffness, low deformation (creep) and high tensile strength, making them suitable for load support, heavy-duty and long-term use.
Proven in the lab and the field… For the past 20 years the engineering performance of Neoloy Tough-Cells established and proven in more than 100 professional published papers and in thousands of projects worldwide. The collaborative testing included leading institutes and authorities around the world, such as the US Federal Highway Administration (FHA) and state Departments of Transportation (DOTs), the Federal Railroad Administration (FRA), KOAC-NPC Road Standards Institute, and other geosynthetics standards and transportation agencies worldwide.
Neoloy Tough-Cells provide 95% performance after 25 years
PRS Solution – What our Customers Say About Us
For the last 15 years PRS Neoloy Geocells solution has proven results worldwide. The following are sample recent projects and testimonials.
New Airport International of Mexico built on a Swamp: leading international engineering consultants and the NAICM authority selected PRS-Neoloy-330 Category C Tough-Cells after extensive testing and trials on problematic soils (CBR <1%).
“The PRS-Neoloy Geocell was the only qualified solution that not only met, but exceeded, all our project requirements…”
Mario Gonzales, Ancora Pavement Engineering, Mexico
Fast Military Access Road Construction, UK Ministry of Defence (MOD): PRS was chosen due to its high-modulus Neoloy Tough-Cells, quality management, large production capability and proven experience in Route TRIDENT Afghanistan, where it helped save lives, reduced the amount of materials used by 75% and save on construction time while under fire.
“Neoloy Tough-Cells reinforcement system enabled a 75% reduction in aggregate use and contributed to a reduction in projected cost of the road by 1/3 as compared to traditional building methods.”
Lieut. Colonel M T G Bazeley Royal Engineers
