Drain allows rainwater and surface water to be drained away from the deck of a bridge. Drain is available in 2 versions :

rectangular drain in aluminium
spiral drain in stainless steel

It ensures safety for users and enhances the sustainability of the strucures. Rainwater and surface water must be evacuated quickly expelled from the bridge.

Drain is an important element in the drainage of water from civil engineering structures with a roadway surface with a permeable macadam.

Prescription

Hydrocarbon covering commonly used for concrete support bridges is permeable, so water tends to accumulate and flow towards the interface sealing/surface course because of the tread. Water damages the macadam. There is a risk to damage the structure if there is a sealing defect so quick evacuation of water is necessary. Installing a rainwater drain system consists of :

transversal drains depending on the traffic
longitudinal drains

It is possible to double the draining capacity by installing two drains side by side.
