As a manufacturer of polymer waterproof materials.
2022-06-14
Yixing Zhonghuan DW Phase IV Project is an important project in Yixing Economic and Technological Development Zone, and the steel structure metal roofing area of this project is about 60,000 square meters. The waterproof layer is made of 1.5mm thickness fabric inner reinforced thermoplastic polyolefin (TPO) waterproof membrane, and the construction method is fixed by non-perforated mechanical construction method.
The advantages of BNBM OTAi non-perforation mechanical fixation system：
- Compared with the mechanical fixing method with perforation, the construction efficiency of mechanical fixing without perforation is higher.
- It is not necessary to fix the edges of each roll.
- No need to consider the width of membrane.
- No need to cut the membrane (reduced membrane lap seams).
- The wind load can be distributed more evenly.
- Improve the level of wind resistance, currently the highest level can reach FM 1-210.
- The roof is more beautiful to look at.
- Improve construction efficiency and reduce labor intensity of workers.

Chongqing Longxing Football Stadium is one of the hosting venues for the 18th Asian Cup in 2023. It is located at the foot of Longnao Mountain next to the Longxing Guzhen, Chongqing. The total construction area of the football field is 166,900 square meters, which can accommodate about 60,000 spectators. After completion, it will be one of the largest football stadiums in China.
The Chongqing Longxing Football Stadium has a steel structure roof with an oval shape. Waterproof content includes metal roofing and gutter waterproofing.
Waterproof material: TPO Reinforced waterproof membrane, TPO fabric backing waterproof membrane.
- Prefabricated waterproof flashing: 16,000 pieces of open pipe wraps
- Waterproofing area: Total area of 36,000 square meters
Otai polymer waterproof material is suitable for all kinds of single-layer roofs and exposed roofs.
Chongqing Longxing Football Stadium is a steel structure roof, oval in shape, with a roof height of 59.5 meters. The wind is strong all year round, so wind resistance is also the focus of the project's waterproof work. TPO membrane has to withstand a long time of tension, and the non-perforated welding disperses the fixed parts evenly, so that each nail is evenly stressed, and the wind resistance system is more stable.
OTAi waterproof prefabs make it easier to handle waterproof details. The use of OTAi pipe wrap prefabricated parts improves the efficiency of construction and reduces the loss of waterproofing membranes.
OTAi will continue to provide excellent products and high-quality services for our customers.
