High density polyethylene/ geocomposite drainage membrane.
Proofex Sheetdrain is a double cuspated geocomposite drainage sheet with 8 mm thick high density polyethylene core and polypropylene geotextile faces. It is fixed to walls and roofs of structures to provide a filtered, drainage plane that will route ground water and gases away from the structure, utilising subsoil drains to link with the site drainage system. Proofex Sheetdrain reduces water pressure on structures and the possibility of water ingress, and can be effectively used in conjunction with other waterproofing systems.
Proofex Sheetdrain can also be used as protection to a sheet membrane against physical damage from backfill operations.
Mechanical fixing using Hilti XSW 30ZE 37 or Proofex Engage Detail Strip (when applied to membrane). Fixing centres: One per square metre.
100 mm integral lap is recommended.
