Interdrain GMFL

Intergrain GMFL is a geonet made form high-density polyethylene (HDPE) laminated by polypropylene (PP) geotextile on one side and by hydroinsulation foil on the other one.
The geonet is made from fibres which intersect at 60° and this pattern creates channels with high flow capacity under pressure and also at very low gradients.

Main uses:

  • horizontal drainage of embankments, roads, railway and tram tracks and other trafficked areas
  • vertical drainage of retaining structures, bridges, tunnels and other underground constructions
  • drainage of playgrounds, waste deposits, landfills etc.
  • effective drainage geocomposite with long life span
  • high drainage capacity even under pressure


  • drainage
  • filtration
  • separation

We supply this product for constructions in the Czech Republic,
Slovak Republic and other countries of the European Union.
