PRS Neoloy Tough-Cells are a green 3D mechanical soil stabilization technology to stabilize all kind of soils, reinforce support layers and deliver the highest pavement performance. Increased performance enables heavy-duty use and extended service life, with the lowest repairs and maintenance compared to unreinforced methods. With engineering properties aligned to transportation and infrastructure needs, Neoloy Tough-Cells present the strongest solution and extended the life of pavements, rails and ports. In addition, Tough-Cells can be used for slope and channel protection, earth retention walls and landfills and reservoirs.
Geocells with granular fill act as a mattress that later distributes applied vertical forces (e.g., vehicle wheel). The confinement restrains the lateral movement of soil particles via hoop stress on the cell walls. The stabilized soil improves layer modulus and reduces surface deformation. However, the extent of the reinforcing or stabilizing effect is determined by the “material from which the product is made …. geocells must also have the right properties … when it comes to dynamic stiffness, resistance to plastic deformation and tensile strength” (Reinforcement Geosynthetics in Road Building Standard(Vega et al, 2018, Netherlands).
Although the geometry of geocells is similar, it is the polymeric material from which they are made that determines their performance. There are 2 main types:
Neoloy® Tough-Cells are rigid geocells made from NPA (Novel Polymeric Alloy), providing the stiffness, strength, and durability required to resist volumetric deformation under dynamic loading throughout the project lifespan – delivering the highest value and the most effective soil stabilization solution. According to global standards, such as ASTM and ISO standards, the three key properties of cells are:
Whereas one size doesn’t fit all, one cell type does not fit all projects. Neoloy Tough-Cells are manufactured in 4 strength categories (C-D) to match the geocell to the specific project requirements. This enables you to customize the geocell configuration to the project and optimize the solution performance vs. cost. Learn how to use Neoloy Tough-Cells Categories to optimize your performance and costs.
PRS Neoloy Tough-Cells are geocells suited to the needs of today’s infrastructure and construction by providing the highest engineering performance at the most effective cost. PRS Neoloy Tough-Cells provide the strongest stabilization, highest reinforcement factors and/or lowest costs (capital and lifecycle) compared to any unreinforced or geosynthetics alternative:
