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
