With the deepening of China’s reforms, international exchanges have continued to increase. During the “7th Five-Year Plan” and “Eighth Five-Year Plan” period, China introduced new production technology and equipment for waterproofing membranes from Austria, Germany, Italy, Spain, and the United States, and introduced production lines successively. With 14 production capacity of more than 90 million m2 per year, China has also independently designed 15 production lines and transformed more than 20 existing linoleum production lines. The total annual production capacity is over 150 million m2. In 1997, the company that introduced the production line produced more than 14.5 million m2 of modified bitumen waterproof membranes. Among them, Liaoning Panjin Yuwang Waterproofing Building Materials Group produced more than 4.5 million m2, an increase of 12.5% over the previous year. Beijing Oakland Construction Waterproofing Co., Ltd. produced more than 2.6 million m~2, Shenyang Languang New Waterproof Material Co., Ltd. produced more than 2.2 million m2.
