Chek Lap Kok Airport (Hong Kong International), Hong Kong

First installed over 15 years ago, Flowcrete's Isocrete K-Screed, a proprietary semi-dry high strength screed, is still going strong at Hong Kong International Airport [HKIA] after millions of passengers have walked all over it. Now the third busiest international passenger airport in the world, HKIA was built between 1992 and 1998 to an innovative design by Foster & Partners.

In the largest screed contract ever awarded at the time, a total of 250,000 square metres of Isocrete K-Screed was applied. Every day since, the system has stood up to continual high levels of foot and trolley-wheeled traffic in the main passenger terminal building, retail, food and entertainment areas, as well as associated maintenance areas and plant rooms.

Isocrete K-Screed, bonded with Polymer 70, was installed at a thickness of 100mm throughout the high traffic site. The reduced water content of the K-Screed provides added strength and durability, eliminating the cracking, curling and debonding that often occurs with standard sand and cement screeds. The superior impact resistance also protects thinner section floor finishes, such as vinyl, for far longer, significantly minimising the need for costly refurbishments down the line. K-Screed is suitable for use with a diverse range of final floor finishes including vinyl, carpet, marble, ceramics and various resin flooring finishes.

All the work at HKIA was carried out by ASTEL, Flowcrete's licensed applicator in Hong Kong. Subsequent phases of the project also included screeding at Cathay City, the headquarters and maintenance terminal for Cathay Pacific, where a number of areas were installed with K-Screed.
