Drainage geotextiles act as a permeable separator that allows water to pass into the drainage system, while preventing soils and other material from clogging the system. Key characteristics of drainage geotextiles are the AOS (Apparent Opening Size), which indicates the size of openings in the material, and Flow Rate, which indicates how much water can pass through the geotextile.
- Woven or Nonwoven material
- Multiple AOS values and Flow Rates
- Custom widths available
