Retention System Build-up
With the ZinCo EcoVap system, your sponge city roof will not only last longer but also provide a healthier plant growth. The green community on your roof is going to thrive to become more resilient, especially against invasive species.

The ZinCo retention system build-up protects a roof from water damage and contributes to a cooling effect of the toplevel of a building. With ZinCo Retention Run-off Limiter Set RDS 28, the retained rainwater on the roof is stored on the roof and slowly relased to the environment. Additionally, with ZinCo Wicking Mat DV 40, the stored rainwater will be gradually drawn upward by capillarity forces, contributing to the specific microclimate, sustaining plants life even during dry and hot months.
