Wa Yizhang’ in Action: Smart Roof Waterproofing for Coastal Areas

Coastal areas face complex climatic conditions, including heavy rainfall, high humidity, strong salt corrosion, and extreme weather such as typhoons and storms. This poses significant challenges for roof waterproofing in these regions. Not only must the waterproofing performance be excellent, but its durability must also be guaranteed. Additionally, roofs must ensure safety during extreme weather to avoid hazards such as falling tiles or other debris. To meet these demands, a roofing waterproofing technology known as "Wa Yizhang" (literally "One Tile")—spray-applied polyurea—is quietly gaining popularity.

With superior waterproofing performance, longer service life, faster construction efficiency, and lower overall costs, spray polyurea roofing waterproofing technology combines numerous advantages. It perfectly integrates solvent-free, pollution-free polyurea materials with highly efficient mechanized on-site spraying techniques, making it one of the "Top Ten Black Tech Innovations."

Showcase of the Effects of Air++ Spray Polyurea Roof Waterproofing Project

Located on the beautiful coastal city of Yantai on the Jiaodong Peninsula, Yantai University faces frequent extreme weather conditions such as summer storms and typhoons, as well as heavy snowfall in winter, earning the region the nickname "snow nest." To address the waterproofing issues of tiled roofs and eliminate safety hazards caused by falling tiles during severe weather, Yantai University has adopted Air++ spray polyurea roof waterproofing technology. Using mechanized spraying methods, the seamless and dense polyurea coating tightly bonds the roof tiles together, creating an integrated waterproof roof known as "One Tile." This solution provides shelter and safety for the students and faculty of Yantai University, protecting them from wind and rain.

The "One Tile" roof waterproofing solution has brought significant benefits to Yantai University in the following aspects:

• It provides the tiled roof with a dense, seamless "raincoat."

• It tightly bonds the tiles together, preventing damage or injuries caused by strong winds dislodging or blowing off tiles.

• It can be applied over existing structures without replacing original materials, significantly saving on material costs and construction time.

• The mechanized spraying method ensures efficient construction, allowing the project to be completed during summer break without disrupting normal academic activities.

• It ensures the roof's overall ability to withstand heavy snow loads without damage.

• It resists erosion from high-salt and high-humidity environments, offering a longer effective lifespan.

• With minimal infrastructure investment, it revitalizes the roof, enhancing the campus's appearance.

With its multifaceted advantages, the "One Tile" spray polyurea roof waterproofing technology is becoming a new favorite in roof waterproofing solutions.
