PRS (Professional Reinforcement Solutions) Mediterranean (PRS-Med, PRS) is an engineering and technology company with innovative solutions for infrastructure, mining, energy exploration and the military based on the PRS-Neoweb geocell, the Tough-Cell cellular confinement system. PRS-Neoweb has been proven in challenging soil stabilization, soil reinforcement and erosion control in geotechnical engineering road engineering, civil engineering, environmental engineering and landscape architecture projects. The high-modulus PRS-Neoweb was designed to optimize geocell performance in: Roads & Rails - highways, RAP roads, low volume roads (access, service, haul), railways; Earth Stabilization - retaining walls; Slope Protection - slope stabilization and erosion control, channel protection and stormwater management; and Geomembrane Protection - reservoirs and landfills.

Geocells were invented by the US Army Corps of Engineers in the 1970’s. Called “sand-grids” they were used to improve soft subgrades to build temporary roads for heavy military vehicles. Subsequent civilian use of geocells began in the 1980’s, such as the HDPE based Geoweb® geocell from Presto Geosystems®. However, unlike their original use, geocells in the civilian market tended to be used for soil erosion control. HDPE geocells were only used in ground improvement for temporary or low volume roads due to concerns about progressive deformation and loss of strength over time.

PRS began its own path manufacturing its own PRS-Neoweb™ brand of geocells after 2004. At the same time PRS embarked on an intensive research program into cellular confinement technology in order to develop geocells suitable for use in modern highway construction. This required a geocell with the flexibility of HDPE but with the low creep and high-modulus of engineering thermoplastics.

The end result was the creation of a completely new generation of geocells based a Novel Polymeric Alloy called Neoloy®. Neoloy is created in multiple layers featuring dual strips around a high strength inner core layer for optimal performance. PRS-Neoweb geocells from Neoloy are specifically engineered for structural reinforcement in demanding applications such as the highway engineering, high retaining walls and heavy-duty roads, railways and ports.

PRS-Neoweb is the cellular confinement system (geocell) developed, manufactured and distributed by PRS Mediterranean Ltd.

PRS-Neoweb is used for cost-effective soil confinement, stabilization and reinforcement in a wide variety of civil engineering applications, such as base reinforcement of paved and unpaved roads, and earth stabilization of slopes and retaining walls.

Leading the industry with specialized geocells that enable cost-effective optimization for any type of project. PRS-Neoweb is the only geocell made from high-strength Neoloy novel polymeric alloy. The unique properties of this alloy enable a strong and stiff geocell with high durability to provide economic, sustainable and engineering value for every project.

Benefits of PRS

Geotechnical

  • Improve infill modulus
  • Reduce layer/infill thickness
  • Distribute loads evenly and increase bearing capacity
  • Reliable long-term performance

Economic

  • Optimize project requirements vs. cost
  • Utilize low cost aggregate infill
  • Lower and all-weather construction costs
  • Increase lifespan and reduce repairs – long term savings

Sustainable

  • Use local, regional and recycled materials for infill
  • Reduce quarrying, hauling, earthmoving, pollution, footprint
  • Enhance vegetation, landscapes, green walls
  • Excellent drainage, filtering and protection from rain, runoff and stormwater

PRS earned its geotechnical expertise from actual field projects worldwide. Its Neoloy®-based PRS-Neoweb™ cellular confinement system was chosen by leading international energy, logging, and mining companies, as well as consultants and contractors, making PRS their “partner of choice”.

PRS product development has been directly influenced by our 15 years of customer relationships and being on-site in over 45 countries, working shoulder to shoulder with civil, environmental and geotechnical engineers, road designers, landscape architects and contractors. PRS-Neoweb offers an advanced “out of the box” sustainable and cost-effective alternative to conventional soil stabilization solutions. PRS-Neoweb performance has been proven in challenging environments – from scorching deserts to saturated peat bogs to frozen arctic tundra.

Today’s trend to use inferior, local or recycled materials and the growing need to develop marginal lands puts 3D cellular confinement systems with a long design-life in an environmental, engineering and economically vital position. PRS Mediterranean’s goal is to be the leading provider of long-term, sustainable high-strength geocell solutions for these ever increasing needs worldwide.

Value Proposition

PRS-Neoweb geocells from PRS are in a geosynthetic class of its own, with strength, durability and performance unmatched by any other geocell, geogrid or geotextile, No longer confined to problematic subgrades, PRS-Neoweb can be used for base reinforcement of all heavy-duty motorways and railways - for higher quality roads at lower costs.

PRS-Neoweb high strength geocells lower the construction footprint. Virgin aggregate use can be cut in half, while regional and recycled materials can be utilized for structural infill.  More importantly, the design-life of PRS-Neoweb matches the long-term requirements of civil engineering and sustainable development.

PRS-Neoweb saves time, money and resources during construction as well as over the project life-cycle. This enables transportation management professionals to reallocate maintenance budgets to the construction of new roads and infrastructure. The bottom line is that PRS-Neoweb provides a wealth of environmental, social and economic benefits in almost any project.
