The Proofex Sheetdrain 80 is a geocomposite drainage sheet with a 8mm thick HDPE cuspated core and non-woven polypropylene geotextiles, recommended for most building and civil engineering drainage applications

  • Cost effective – no need for up to 500mm thick stone drainage layer behind retaining walls
  • Easy site application
  • Reduced environmental impact – no need for vehicular removal and transportation of spoil off site and subsequent replacing with expensive stone drainage layer
  • High flow rate (water and gas)
  • High impact resistant, HDPE cuspated core with a compressive strength of up to 200 kN/m² provides drainage void around structures under backfill and long term loadings
  • Cost effective alternative to ‘French Drains’
