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
