Advantages

  • High rainwater retention -> nearly 19.59 l/m2 of water storage capacity
  • Prevention of water channel system overuse -> waterflow speed decreased by stepped barriers
  • Microbiological resistance test (EN 12225) -> additional protection for the waterproofing layer against microbiological damage
  • Recessed evaporation vents -> unobstructed aeration
  • Increased contact area -> decreased surface pressure
  • Durable and high impact-resistant material (HIPS) -> stability under pavements, water cooling is not needed during summer installations
  • Negligible overlap loss economical installation and cost savings
