Deckdrain 4S50
DECKDRAIN 4S50 is a 4.7mm 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
- 4S50 has a higher density (770 g/m2) than 400 S
