The driving surface retention system design is an effective way of delaying rainwater runoff and adding it to the natural water cycle through evaporation. Installing driving surface on a roof requires a robust solution that can withstand the load from vehicles. In addition to the system design, the load-bearing capacity of the roof structure and the impact of forces acting on it horizontally also need to be taken into account. Rainwater retention does play an important role on green roofs, but water needs to be drained quickly from road surfaces so that it doesn’t stay there for too long. Which is why good drainage is important.
