Revitalization Kai Tak
Kai Tak International Airport, the former international airport of Hong Kong, is undergoing a radical clean-up and revitalization operation. TenCate Geosynthetics is closely involved, as the TenCate Geotube® technology turned out to be the most cost-effective, most professional and, from the environmental perspective, most attractive solution.
Kai Tak was the international airport of Hong Kong from 1925 to 1998. The former airport is located in the business and residential district Kowloon City. This location and the approach route of the aeroplanes made Kai Tak International Airport one of the most dangerous airports in the world. Over time the soil, the approach channel and the Kwun Tong Typhoon Shelter have become contaminated.
A total of 140,000 m3 of contaminated sludge must be removed, dewatered and stored − which corresponds to 7,000 truckloads. The contaminated sediments will be stored in TenCate Geotube® containers and shipped for disposal in the confined contaminated mud pits located offshore of the new Chek Lap Kok Airport.
Land disposal is very expensive in Hong Kong but with TenCate Geotube® the sludge can be removed in an economically and environmentally responsible way. Furthermore, the customer was highly impressed with the professional approach of TenCate Geosynthetics.
