Polyfelt Megadrain


Polyfelt® Megadrain

Polyfelt® Megadrain drainage composites are monofilament geomats from polypropylene, with a filter nonwoven on one or on both sides. The extremely high voids content of Polyfelt® Megadrain ensures a high water-flow capacity, especially at low overburden pressures. 


  • Reduced excavation and construction costs
  • The high in-plane flow rate of Megadrain corresponds to 20-30 cm of drainage gravel.
  • One roll of Megadrain weights just 24-35 kg, replacing 15-25 tons of gravel.  
  • Polyfelt® Megadrain can be installed easily.
  • The controlled product quality of Megadrain guarantees constant filtration and drainage performance.
  • The use of Polyfelt® TS as filter guarantees optimum soil retention capability and water permeability. 
  • Polyfelt® Megadrain is chemically and biologically resistant and absolutely environmentally friendly.
