- Delayed rainwater runoff stepped barriers avoid overuse of wastewater channel system
- Runoff reference value (C) 0,29 -> water delay over 70% according to FLL1
- Microbiological resistance test (EN 12225) -> protective function for waterproofing against biological effects
- Recessed evaporation vents -> unobstructed aeration
- Negligible overlap loss -> economical installation and cost savings
- Increased contact area -> decreased surface pressure
