The second phase of the expansion project of Yuyang Airport in Yulin City started construction in April 2018, and Tianjin Binhai Otai undertook the construction of the waterproof project for the metal roof of the passenger terminal building.
The construction area of the main building is 30,000 square meters. After many discussions, Tianjin Binhai Otai selected polyvinyl chloride (PVC) waterproof membrane for the project and provided professional technical services.
"OTAi" PVC waterproof membrane has the characteristics of good water vapor diffusion, chemical corrosion resistance, wide membrane width, high construction efficiency, and low product loss.
