Large-scale utilization, e.g. in docks, storage areas, production halls, container railroad stations, and airports have one thing in common: they must be able to resist extremely high traffic loads. Here, reliably functioning surface drainage of the mostly extensive areas is especially important. For these applications, Hauraton, with its Faserfix Big series offers new runner channels that provide optimal hydraulic performance. Heavily loaded areas benefit in particular from these drainage systems, which are fitted with solid concrete runners and enable quick laying with heavy equipment.
