Deckdrain 4SX50D
DECKDRAIN 4SX50D is a 5.9mm deep geocomposite drainage layer suitable for smaller podium decks and car parks where drainage outlets are closely spaced.
Area of use
- The major application is for use as a drainage layer in structural applications on roof decks and in subsurface works
Specific properties
- Single cuspated HDPE core with a geotextile filter thermally bonded on the dimple side and a friction geotextile thermally bonded on the flat side
- Textile filter has a flap extending beyond the core on one edge
- The core is perforated to allow drainage from both sides
- 4SX50D has a higher density (940 g/m2) than 4SX25D
