2023 Building waterproof material industry: the industry market demand continues to improve the industry development prospects

Building waterproof material is the maintenance structure of the building, the role is to build a waterproof layer on the surface of the building, in order to achieve waterproof and anti-leakage purposes. Since the reform and opening, with the rapid development of national economy and the continuous expansion of construction industry, the waterproof material industry has entered the rapid development period. At present, waterproof materials are mainly divided into two categories, waterproof coil accounted for about 65%, waterproof coating accounted for about 25%. The industry chain of waterproof materials is clear. The upstream raw materials are mainly petrochemical products, while the downstream demand is concentrated in the field of construction engineering. The main raw materials of waterproof materials include asphalt, polyester base, SBS modifier, emulsion, etc., which is closely related to the petrochemical industry, so it is greatly affected by the international crude oil market. The application field of waterproof materials covers many aspects of the construction industry, mainly including housing construction, transportation infrastructure, municipal engineering, water conservancy facilities, etc., which has a strong correlation with national real estate investment and infrastructure investment.

Building waterproof material is the building envelope structure, can prevent rain, snow water, groundwater, industrial and civil water supply and drainage as well as air moisture, steam and other erosion of the building, mostly used in the roof, underground building, underground part of the building and the need for waterproof inner room and water storage structure. Building waterproof materials are mainly divided into waterproof coil and waterproof coating two categories. In recent years, the output of building waterproof materials has increased rapidly in China. According to the China Building Waterproofing Association, the country's output of building waterproofing materials in 2021 will reach 4.092 billion square meters, up 8.4 percent year on year. China Commercial Industry Research Institute forecasts that the country's building waterproof material output will increase to 5.81 billion square meters in 2023.

At present, the product structure of building waterproof material is mainly composed of SBS/APP modified asphalt waterproof material, synthetic polymer waterproof material, waterproof coating and self-adhesive waterproof material. In 2021, SBS/APP modified asphalt waterproof coil accounted for 36.06%, waterproof coating accounted for 25.89%, self-adhesive coil accounted for 22.64%, polymer coil accounted for 11.16%, a total of 95.75%. Among them, waterproof coil is still the main type of waterproof material, accounting for 69.86%.

Waterproof materials are mainly used in the basement, roof, kitchen and bathroom, exterior wall and so on in the building construction, among which the basement accounts for the highest proportion; In infrastructure construction, it is used for highway and high-speed railway Bridges, tunnels, urban roads and Bridges, underground pipe gallery and underground space and other municipal engineering, underground railway and other traffic engineering, diversion channel, reservoir, dam, water power station and water treatment and other water conservancy projects. According to statistics, residential, civil construction, infrastructure, industrial buildings accounted for 50%, 20%, 20%, 10% of the waterproof demand. Among them, the residential field waterproof application to the basement, kitchen and toilet, roof mainly. In addition, because the indoor kitchen, bathroom because of small waterproof area and more details, the use of coil is not easy to deal with details, so the basic use of waterproof paint.

Building waterproof material is an essential functional building material for modern buildings. It is mainly used in real estate development, infrastructure construction and other industries. Its development trend is closely related to the economic development environment. Since the reform and opening up, our national economy has maintained the momentum of rapid development, and the sustained high rate growth of our national economy has provided sufficient development space for real estate development, infrastructure construction and other industries.
