KerbDrain BridgeDeck

Combined kerb and drainage system for bridges

Effective management of surface water on bridges is crucial for ensuring road user safety, reducing maintenance costs, and preventing erosion that can shorten the service life of bridge structures.

ACO KerbDrain Bridgedeck is a versatile combined kerb and drainage system designed to effectively manage rainwater on bridges. These one-piece units are certified up to Load Class D 400 and are available in both Half Battered (HB) and Splayed profiles (SP) to meet different site requirements.

The product is manufactured from ductile iron and is a Type I system, which means that no concrete bed surround is required for installation. Additionally, the range includes expansion joint solutions that prevent water damage to the joints and allow the flow of water to continue from the bridge to the highway.

Connection to KerbDrain - BridgeDeck is compatible with our award-winning ACO KerbDrain range, allowing for a seamless transition from Bridge to Road.
