Nidaroof is a rigid plate with an hexagonal alveolar structure and covered by a synthetic non-woven one side or two-sides according to use. It has a very high compression resistance and at the same time an excellent emptying rating. Nidaroof is an essential part of our Wateroof Management which is the first complete system technically validated to retain rainwater.

  • Temporary or permanent water retention
  • Light backfill in case of green roof or under pedestrian protection
