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
