Application

For horizontal roofs and decks. Suitable for draining and irrigating green roofs or planter boxes. Principal applications:

  • Conventional green roofs;
  • Low maintenance green roofs;
  • Landscaped inverted roofs;
  • Concrete decks with planted areas;
  • Podium deck planter boxes.

Description

Polypropylene non-woven filter fabric on one face of an 12 mm studded drainage core with a separation geotextile bonded to the other face. For low and regular maintenance green roofs and planter boxes with minimum falls of 1 in 80.


Features and benefits:

  • Polystyrene has minimal creep under long term loading.
  • Fully compatible with GCP waterproof membranes.
  • Provides additional factors of safety against water penetration through roof decks.
  • Range of filter fabrics to cover hard and soft landscaped finishes.
  • Range of compressive strength cores to suit different loading and trafficking conditions.
  • Provides an efficient, low cost drainage plane to horizontal roof decks.
  • Geotextile filter fabrics prevent soil particles entering drainage core.
  • Rot proof.
  • Easy installation.
  • Provides both water discharge and retention functions for low and regular maintenance green roofs.

General information

Finish

A variety of surface finishes can be laid directly on top of HYDRODUCT® drainage sheets, dependent on deck use. Contact GCP Technical Services for further guidance.
