Neoloy® Tough-Cells Provide Confinement in All Directions

Geotextiles are designed for separation and drainage, while Neoloy Tough-Cells are designed for soil stabilization and reinforcement.

Geotextiles are widely utilized in geotechnical engineering for road, slope and earth stabilization. Although primarily used for separation and drainage (filtration), geotextiles also have  a small contribution to soil reinforcement. This is achieved by allowing water to flow through the geotextile while preventing the movement of soil particles. This preserves the soil integrity, thereby extending the life of the road surface.

However, 3D Neoloy Tough-Cells confinement actually reinforces the modulus of the infill soil, thereby increasing its bearing capacity. . 2D planner reinforcement provides very limited vertical confinement, while Neoloy cellular confinement systems provide confinement in 3 directions  (i.e. along the entire cross-section of each cell) with a zone of influence beyond that of the cell height (50-200 mm). Moreover, the multi-cell geometry provides passive resistance that increases the bearing capacity. In addition Neoloy Tough-Cells can provide soil reinforcement to marginal granular materials, such as recycled asphalt, crushed concrete, fly ash and quarry waste.

Benefits of Neoloy Tough-Cells over Geotextiles

  • Effective reinforcement – 3D geocell reinforcement mechanisms
  • Very high strength and stiffness – tensile strength up to 24 kN/m
  • Improves modulus – of infill soil and structural layers
  • Longer lifespan – high resistance to deformation under dynamic loading
  • Low environmental impact – reduces aggregate use and associated environmental costs
  • Sustainable solution – reduced repairs and maintenance due to long pavement life
  • Cost effective – lower construction costs and lifecycle costs
