Mirafi® RS380i Geosynthetic

Mirafi® RS380i Geosynthetic

Because Mirafi® RSi-Series Geosynthetics have higher tensile modulus properties than comparable stabilization products on the market today, it is perfect for base course reinforcement and subgrade stabilization in roads, railways, runways and haul roads; and for stabilization of embankments on soft foundations. It also performs well for liner support, voids bridging, hazardous pond closures and other environmental purposes. Mirafi® RSi-Series geosynthetics are available in a variety of roll sizes to fit your specific project needs and requirements.

Mirafi® RS380i is a specially designed geosynthetic that integrates key performance characteristics to maximize performance. Extensive performance testing has been performed per AASHTO and FHWA guidelines to validate performance for both paved and unpaved roads. The patented weave pattern and unique orange identifier yarn make the Mirafi® RS380i a unique performance geotextile.



  • Modulus: Separation. Confinement. Water flow. Orange product identification. Superior integration*.
  • Reinforcement Strength: Higher tensile modulus properties than the leading stabilization products.
  • Separation and Filtration: Unique double layer construction provides a wide range of pore sizes for an excellent separation factor, superior filtration and flow characteristics of a fine to coarse sand layer.
  • Soil and Base Course Interaction: Excellent soil and base course confinement resulting in greater load distribution.
  • Durability: Robust damage resistance for moderate to severe stress installations.
  • Roll Sizes: Mirafi ® RSi-Series geosynthetics come in several roll sizes to fit project requirements.
  • Seams: Panels can be seamed in the factory or field, providing cross-roll direction strength to facilitate efficient installation.
