Advantages
- High rainwater retention→ca. nearly 12 l/m2 of water storage capacity
- 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)→stepped barriers avoid overuse of wastewater channel system
- Recessed evaporation vents→unobstructed aeration
- Negligible overlap loss→economical installation and cost savings
- Increased contact area→decreased surface pressure
