ND 600 serie Drainage Systems


3-in-1 product

All our ND Drainage Systems are delivered on roll. They are a 3-in-1 product consisting of a woven or non-woven filter geotextile, a dimpled core (with / without perforation and with / without water buffering), a separation and protection geotextile or a pressure dividing slip film.

This sandwich element aspect has many benefits! Easy to transport and unroll and fast to install.

E.g. for the ND X20 Drainage System a standard truck can be loaded with up to 3.600 m² (144 m² per pallet). This are features that help to reduce installation and transportation cost.


Benefits of the ND 600 serie Drainage Systems

  • Direct application of sub-base layer or drainage concrete on top of the drainage system possible through special monofilament woven filter.
  • Extremely high compressive strength up to approx. 1,200 kPa ensures that dimples do not deform during high loads, so that drainage remains optimal.
  • Under 10 % deformation the compressive strength stays high (approx. 1,000 and 800 kPa)
  • Suitable for working with vibrating plate due to high compressive strength and special monofilament woven filter.
  • Thin construction; less plastic on the roof.
  • Protects against dynamic and static loads. 
  • 3-in-1 sandwich element on roll ensures easy installation.
  • Fit for purpose: options for warm roof constructions, roof constructions without thermal insulation and inverted roof constructions.
  • Fully tested on protection by means of an index test: assessment on the level of protection provided by the protection layer.
  • Fully tested on performance: Assessment of the performance and behaviour of a pavement structure under simulated trafficking conditions performed at the Technical University Munich.
