drainage fabricGeotextile Drainage Fabric Applications

Mirafi® non woven geotextile is ideal for erosion control, drainage, and filtration. Creating effective, long-term drainage solution, this soil separator fabric is designed to survive construction, allowing the passage of water at high rates, and retaining insitu soil (stop piping soils) without clogging. This nonwoven geotextile provides enough strength and abrasion resistance to withstand application stresses and installation. Common uses for rip rap drainage fabric are: cut-off/interceptor drains along rode ways, liner protection within landfills, and French Drains without the use of pipes.

Other drainage applications are:

  • Erosion Control
  • Soil Separation
  • Drainage
  • Filtration
  • Geo-membrane Liner
  • Recharge Basins
  • Relief Wells
  • Edge Drains and more
