The drainage of rain from roads

Rainwater that falls on paved surfaces, such as roads, cannot simply soak into the ground. What if a large amount of rain falls in a very short time? The consequences of this on and around roads can be very serious. Flooding can arise very quickly during extreme downpours. It causes empty streets and tunnels that have to be closed. Roadworks that have to be carried out as a result of essential maintenance to resolve the problems often cause traffic chaos. Road users are confronted with longer journey times as a result of road closures, diversions and traffic jams. That's why highways authorities try to limit the overload as much as possible and prevent problems.

The delicate function of a road therefore also demands a system for the drainage of rainwater that features a long life and adequate flexibility.
