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.     Construction method: 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.     OTAi is a comprehensive waterproof enterprise integrating scientific research, production, sales, construction and technical services. It has strong technical strength, excellent R&D team and advanced scientific research equipment. OTAi's waterproofing products mainly include TPO/ PVC/ HDPE  waterproof membrane, polymer-modified cementitious waterproof coating and waterproof prefabricated products. The company has introduced international advanced application technology to form a product system focusing on drain, photovoltaic, exhaust, fastening and detail prefabrication. BNBM OTAi will continue to provide excellent products and high-quality services for our customers.
