Drainage channels for airports
Drainage systems in airports face especially high demands. Loads are extremely high on hangars, their surrounding areas, taxiways and runways - especially for channel systems:
- High forces generated by aircraft movements and special vehicles driving backwards and forwards - the monolithic structure ensures that loads are reliably withstood and deflected. Traffic safety cannot be endangered by loose parts or flying fragments.
- Great run-off volumes due to large paved areas - the high absorption capacity prevents water collecting on the surface and minimises the risk of aquaplaning. The high flow-off rate allows a greater spacing between manholes and the number of connection points to the sewer network can be kept low.
- Large temperature fluctuations and the effects of frost and de-icing agents in winter - the durability provided by our proven concrete optimised for the application ensures a long service life.
- Environmentally hazardous substances, such as accidental spillages of kerosene during refuelling or de-icing agents in winter - robust materials which are resistant to hazardous substances reliably seal the drainage system and stop hazardous substances seeping into the ground water. For refuelling stations and de-icing areas, we offer »Pfuhler Schlitzrinnen System Z«, our slot units with general building approval to be used in facilities for the storage, filling and transfer of water polluting substances.
The technical directive is the official notice for the drainage of aviation facilities, issued by the Research Society for Roads and Transport (Forschungsgesellschaft für Straßen- und Verkehrswesen (FGSV)).
