Flownet® Biaxial Drainage Nets
Easy installation drainage system for steep slopes
Flownet® is a lightweight drainage net used on landfill caps, tunnels and behind retaining walls and bridge abutments. It protects structures against high water pressure and is particularly well suited to vertical or steep slope drainage systems. Flownet® offers a cheaper alternative to traditional granular drainage layers.
Flownet® can be supplied in three configurations:
- Net alone.
- Net with bidim® nonwoven geotextile bonded to one side.
- Net with bidim® nonwoven geotextile bonded to both sides.
The geotextile covered net allows for rapid drainage while preventing soil particles from being washed into the drain.
