Analysis of China's waterproof membrane market

Page view

In recent years, China's sponge cities, urban integrated pipeline corridors, new infrastructure investment, house repairs and old renovations have continued to expand, which has promoted the rapid growth of market demand for the waterproofing membrane industry, and China's waterproofing membrane industry has entered a stage of development.

 

 

Waterproof membrane is a rollable sheet-shape waterproof material, used in building walls, roofs, tunnels, highways, landfills, etc., to resist the leakage of external rainwater and groundwater. In recent years, with the development of the national economy and the continuous growth of the construction industry, China's waterproofing membrane industry has developed rapidly, with the continuous increase of new materials and new processes, and the significant increase in production capacity. The product quality of some key enterprises has reached the international advanced level.

 

Most of China's waterproof building material companies are waterproofing membrane manufacturers. According to the statistics of the China Building Waterproof Association, the number of companies above designated scale of China's waterproof building materials (main business above 20 million RMB) from 2016 to 2020 is fluctuating. In 2018, the number of waterproofing enterprises above designated size in China reached 784, it is the maximum number in recent years.

Waterproof materials are mainly used in roofing, underground, kitchen and bathroom, external walls and other parts in housing construction, of which roofing and basement account for the highest proportion; The facilities are mainly used in railways, rail transit, bridges, tunnels, underground pipe corridors, airports, reservoirs, water conservancy and other fields.

Weifang Sunshine Union Hospital Project
Abstract:
    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.
