PRS-Neoweb™ gravity walls mechanically stabilize unstable slopes, prevent erosion and offer a green fascia.

Installation is fast and efficient as each infilled PRS-Neoweb layer is structural stable against rotational failures and internal forces. Neoloy®-based PRS-Neoweb™ provides sufficient structural strength using low grade and/or local granular soil for infill. PRS-Neoweb gravity walls are strong, acting as a modular block, yet flexible structures with high resistance to seismic loading and cracking.

Neoloy-based PRS-Neoweb (unlike HDPE geocells) features long-term stiffness, high UV protection, low creep and very high dimensional stability in thermal cycling. This prevents the ratchet effects from expansion and contraction due to temperature changes that can lead to progressive failure and rupture.

Benefits

  • Effective service range of – from -60°C to +60°C
  • High resistance to photochemical degradation – leaching of additives, oxidation and UV light

The Neoloy Advantage

While most commercially available geocells are made of HDPE, PRS has developed a completely new material for its PRS-Neoweb geocells based on a new patented polymeric alloy, called Neoloy®.

Neoloy is characterized by flexibility similar to HDPE with elastic behavior similar to engineering thermoplastic. Major documented improvements over old generation HDPE geocells are better creep resistance and better retention of stiffness and creep resistance at elevated temperatures and over the long-term.

The engineering advantages of Neoloy over HDPE-based geocells can be measured by accepted testing procedures and verifiable scientific testing methods. Numerous studies, field trials and laboratory tests have demonstrated improved performance in load support applications due to the improved stiffness and strength provided by Neoloy.
