Waterproofing huge structures can pose large-scale challenges not seen in regular waterproofing projects. Facilities such as airports, sports complexes, or luxury spa and resorts are just some of these structures that go beyond routine waterproofing. Waterproofing contractors deal with different variables and deal with them in larger-than-normal scales.

The project scope can be daunting. It’s not hard to imagine the huge amount of waterproofing deck coating products needed to protect the decks and floors of an international airport, for example.

The waterproofing deck coating products used for large-scale projects must be of top quality. The barrier systems must consist of epoxy primers and polyurethane membranes that deliver superior performance. To ensure coatings effectiveness, water testing of the installed barrier system is a major undertaking. Comprehensive leakage evaluation is integral to ensure waterproofing success and to avoid failure.

A recent waterproofing challenge was posed by the Beijing Olympic Games. The project involved construction of massive proportions both underground and above. The facility featured artificial lakes and wetlands, an aquatic park, several large buildings and many competition venues. The waterproofing project used both domestic and foreign materials, new technology and expertise to complete.

With size comes complexity, because large-scale waterproofing demands perfect integration with the facilities’ mechanical systems, deliver longevity, perform well and remain easy to implement despite the larger proportions.
