Ninghe FAW-Volkswagen Tianjin Sixth Factory Parts Logistics Base Project is located in the FAW-Volkswagen North China Production Base in TEDA (Tianjin Economic and Technological Development Area). This project covers an area of 155,000 square meters, with a building area of 32,000 square meters. It will build LOC4# warehouse, joint power station, office building, training center, parking lot etc. The total investment of the project is about 250 million RMB.
The main building of Ninghe FAW-Volkswagen Tianjin Sixth Factory Parts Logistics Base project is more than 20,000 square meters, using TPO single-layer roof waterproof system, and other supporting facilities use PVC or modified asphalt waterproofing membrane.
BNBM OTAi undertakes the supply and installation of waterproof materials for this project. Its TPO waterproof membrane is made of imported raw materials from Basel, Europe, with first-class quality; in the application of construction methods, the use of non-perforated mechanical fixation method effectively reduces the risk of water leakage, disperses the wind, and improves the wind resistance of the roof waterproof layer.

GF (Chengdu) integrated circuit manufacturing project is located next to Binhe Road in the western campus of Chengdu High-tech Zone, covering a total area of nearly 760,000 square meters, and is the largest and most technologically advanced production base of GLOBALFOUNDRIES.
GF (Chengdu) integrated circuit manufacturing project adopts double-layer fortification in waterproof design, and its upper layer or exposed part adopts the world's highest-end polyolefin (TPO) waterproofing membrane.
The TPO waterproofing membrane of Tianjin Binhai OTAi Waterproof Material Co., Ltd. has passed the highest standard of FM certification, and has good performance in flame retardant, wind resistance, hail resistance and other indicators. OTAi TPO waterproofing membrane covers an area of nearly 140,000 square meters in this project. The raw materials of TPO waterproof membrane are imported from Basel, Europe.
1, The concrete roof adopts full adhesion method;
2, The steel structure roof is constructed by mechanical fixation method.
The TPO full adhesion system and self-adhesive membrane double set up, effectively eliminating the hidden waterproof layer of concrete roofing string of hidden water; The mechanical fixing method adopts OMG gasket imported from the United States, and the non-perforated construction method effectively reduces the risk of leakage, evenly distributes the wind load, and improves the wind exposure resistance of the roof waterproof layer.

Sunshine Union Hospital is located in the National High-tech Industrial Development Zone, Weifang City, Shandong Province, covering an area of 630,000 square meters, of which the first phase has a construction area of 280,000 square meters.
The roof of this project is a concrete structure. Due to the long service life, the bonding mortar at the bottom of the original roof floor tile paving layer is aging and cracking, resulting in the floor tiles falling off and poor sealing. The original waterproof layer and the sealing of the detailed nodes have leaks, and it is difficult to achieve the purpose of waterproofing by local maintenance, which will affect the normal use of the top layer.
In order to completely solve the roof leakage, the hospital carried out the overall waterproof reconstruction of the roof. The project adopts the "OTAi" brand TPO membrane of Tianjin Binhai OTAi Waterproof Materials Co., Ltd.
Tianjin OTAi thermoplastic polyolefin (TPO) waterproofing membrane adopts imported raw materials from Basel in Europe, and has passed the FM certification of the United States. The artificial climate aging resistance up to 9000 hours.
The roof waterproofing renovation of Weifang Sunshine Union Hospital adopts double fortification. The first layer of waterproofing adopts Tianjin OTAi SR Polymer-modified Cementitious Waterproof coating 1.5mm to form a film, and then is covered with Tianjin OTAi (TPO) self-adhesive waterproof membrane. The large surface is covered with sticky construction, and the seams are welded by hot air. The two waterproof layers complement each other and provide comprehensive waterproof protection for the roof.
Tianjin OTAi focuses on the cutting-edge technology and high-end products of building waterproof materials, and “promotes the development of China's waterproof industry with innovative materials and complete solutions”. Tianjin OTAi strives to become the world's leading supplier of waterproof systems.
