SUPERIOR WATER MANAGEMENT FOR EXTREME CLIMATES
For projects that require greater stormwater control than the HIGH 25-C can provide, Urbanscape Green Roof HIGH 40-C Premium delivers
elevated resilience and capacity. Its Urbanscape Drainage with Buffer Q40-C expands drainage and integrates a water reservoir that attenuates
peak flows, slows and extends discharge to the sewage system, and minimizes runoff during heavy rainfall.
Combined with the exceptional water retention of the Urbanscape Green Roll, the system offers outstanding retention and detention performance:
the Green Roll absorbs stored water during dry periods, while the Q40-C layer buffers stormwater to reduce pressure on municipal infrastructure.
Designed for storm-prone and arid regions, HIGH 40-C achieves this enhanced performance while maintaining the core Urbanscape advantages—
lightweight construction, a slim, simple build-up, and fast installation. Engineered for climate-adaptive urban developments, it delivers smarter
water management, sustained plant hydration, and long-term reliability.
