Although summer is a busy season for roofing contractors, 60 industry peers set aside some time to participate in NRCA's largest study tour to date, China Roofing & Waterproofing 2002 held in Beijing July 30-Aug. 4.
Participants had the opportunity to visit the First China International Exhibition for Roofing & Waterproofing Technology, which consisted of 159 foreign and domestic exhibitors and was attended by about 10,000 people. In addition to the trade show, a collection of dissertations was presented at the Second China International Symposium on Waterproofing Technology and Market, which offered information about various roofing technologies, demographics of the Chinese roofing market and construction projects for the 2008 Olympic Games in Beijing.
While in Beijing, study tour participants visited a construction project in its initial stages. Because of Beijing's water table, most construction in the area begins by waterproofing a building's foundation to prevent water saturation from the ground. Participants saw a Carlisle two-ply APP-modified bitumen membrane applied to five mud slabs each with an area of about 25,000 square feet (2250 m²).
