Hobas Drainage Pipe installed in Croatia

Croatian road authorities used Hobas CC-GRP Drainage Pipe Systems for some of its biggest construction projects, such as the Dreznik, Viaduct and Dobra Bridge, both near Karlovac, and the Dubrovnik Bridge.

More than 400 kilometres of highway are currently under construction from Croatia's northern borders to the southern seacoast. Hobas Engineering GmbH is based in Klagenfurt, Austria.

The bridges are exposed to highly aggressive drainage water in the winter, and the pipes are constantly exposed to UV radiation. Hobas pipe systems are lightweight and resistant to abrasion, corrosion and UV radiation, features that helped Hobas win the contract.
