SITUATION:
Radio Television Hong Kong is the public broadcasting service of Hong Kong. It currently operates seven radio channels and three television channels, and produces educational, entertainment, and public affairs programmes that are also broadcast on commercial television channels. These radio channels are being on-air nonstop everyday, all round 24 hours.
SOLUTION:
Existing waterproofing system was found aged and a number of waterproofing seepage have been noted. It was challenging to have a complete re-roofing of a 24-hour operation building without noise nuisance.
Sheltercoat 157 PU spray applied membrane system is capable to be applied directly on the existing roof concrete tile, concrete surface or metal surface without removal.
Due to this application method, there will be no noise disturbance and waste material from the site, which is also an environmental friendly re-roofing solution.

SITUATION:
The opening of Kwai Tsing Theatre was in November 1999. The Theatre’s 899-seat Auditorium is equipped to cater for all types of performances. Over the past fifteen years, the Theatre has provided quality support to numerous local and visiting stage productions to the spectacular enjoyment of its audience. In order to enhance and upgrade the waterproofing ability of the 8500m2 roof, Ardex waterproofing system was specified to meet with the high quality requirements, and to reduce the total construction time to minimize impact to the public.
CHALLENGES:
The contract period was short to minimize the impact to the public.
The theatre was close to residential area, pollution and noise control were very important.
SOLUTION:
Ardex sheltercoat system was used to address these issues. The existing roofing system could be retained as to reduce landfill loading, air pollution and also noise pollution. The low VOC features of the system also benefited the citizens. The super high application efficiency reduced the disturbance to the public. The excellent adhesion and chemical resistance made it ideal for regular maintenance traffic.
WPM300, Sheltercoat 157 and ShelterTop were specified. The whole renovation process did not involve any demolition work. Noise and pollutants were eliminated. The shows in the Theatre could be carried on without any disturbance by the construction work.

Wynn Palace (Cotai) is an integrated resort owned and operated by Wynn Resorts in Macau, China which has thrilled guests for more than four decades. With the debut of the 28-story Wynn Palace and a construction floor area of around 450,000 square meters, the magnificent retreat brings together elements that represent the finest in upscale resort living: 1,706 supremely sumptuous rooms and suites, a casino, an 8-acre performance lake, gondolas, meeting facilities, spa and salon, and retail and dining venues.
SOLUTION:
Wynn Palace requested a quick dry, quick cure and quick set materials for patching up carpark flooring and levelling up the wall area.
Ardex Hong Kong worked together with the main contractor and provided a fast track solution:
ARDEX WPM300 water based epoxy working as a primer which can withstand rising damp and enhance the bonding.
ArdurapidTM formulation in both ARDEX A45 and ARDEX A46 allowing fast-track installation work.
ARDEX B12 providing a find smooth finish over both concrete and render. Thickness from feather edge to over 10mm. Quick setting allows further finishing materials to be applied on top in days.
SITUATION:
Shangri-La Group owns a number of luxury hotels and resorts throughout the world’s major cities and tourist attractions. International hospitalities and luxury facilities of Shangri-La bring unforgettable enjoyment to guests all over the world.
CHALLENGES:
As a five star hotel, Shangri-La has very high requirements on water proof job and tile installation.
Swimming pools and Spa rooms are located in a humid environment for a long time. It means both waterproofing and moisture-proofing are needed. In order to avoid potential dangers caused by humidity, it is necessary to set the coating for anticorrosion based on the structure of the pool.
For illustration, the swimming pool of Tianjin Shangri-La Hotel is located on the third floor of the building. To make sure neither rising damp nor leak would occur in the future, high quality of waterproofing on the negative side of below grade surface is necessary to adjacent floors.
Normally, pools are filled in with water for a long time. The chlorine in the water is acidic. Lime scales and mosses can easily accumulate at the bottom of pools as well as pool walls. It impacts beauty of the swimming pool under the circumstances of acid-Alkali corrosion.
SOLUTION:
Use ARDEX WPM 300 water based epoxy membrane and ARDEX WPM 006 water proofing membrane as professional solutions to waterproofing, moisture and negative hydrostatic pressure resistant damp poof.
As a tile adhesive, ARDEX X 24 has excellent tensile adhesion and water resistance. It retains high performance of bonding strength in swimming pools area when using with ARDEX E 72. And ARDEX E 72 works as an enhancer of tile adhesive which also has high performance on acid and alkali resistance. Using ARDEX X 24 with ARDEX E 72 is a reliable combination on swimming pool tile installation.
Use ARDEX EG 2 Epoxy Grout would minimize the impact of lime scales and mosses. ARDEX EG 2 contains antimicrobial protection and outstanding stain resistance. It would perform perfectly on anti-pollution in swimming pools.
