With their aprons and taxiways, airport areas place special demands on drainage plans. These plans have to factor in extremely high loads as well as a high degree of security. The HYDROblock monolithic heavy-duty drainage channel system made from ductile cast iron, the MAXI F1 high-security drainage channel system and the MAXI PRO drainage channel system with an extremely high hydraulic capacity are all ideally suited towards being installed in airport surfaces.
