Waterproofing membranes are essential functional materials required by the construction industry and other related sectors, and form a vital component of the building materials industry. Waterproofing membranes primarily include SBS/APP modified bitumen waterproofing membranes, self-adhesive membranes and polymer waterproofing membranes. Among these, polymer waterproofing membranes are rapidly increasing their market share thanks to their outstanding durability, excellent corrosion resistance, eco-friendly properties and ease of installation. In recent years, with the acceleration of urbanisation and continuous investment in infrastructure development, market demand for polymer waterproofing membranes has experienced explosive growth. Whether in residential and commercial buildings or infrastructure projects such as transport and water conservancy, the application of polymer waterproofing membranes is indispensable. Against this backdrop, the scale of China's polymer waterproofing membrane market has been gradually expanding. Data indicates that the market size for polymer waterproofing membranes in China is projected to reach approximately 21.808 billion yuan by 2024. Looking ahead, driven by government policies supporting green building materials and increasing environmental regulatory pressure, the market size for polymer waterproofing membranes in China is set to continue growing.

The Chinese polymer waterproofing membrane industry will accelerate its transition towards environmentally friendly practices, with a particular focus on the research, development and application of solvent-free and low-VOC materials. As environmental regulations tighten, traditional asphalt-based substrates will gradually be replaced by recyclable polymer materials such as TPO and HDPE, thereby reducing pollution emissions during the construction process. At the same time, the industry will explore the industrial application of bio-based polymer materials, such as plant-derived polyurethane and other green raw materials, to reduce the carbon footprint across the product's entire life cycle. Improving waste recycling systems will also be a priority, with the aim of recycling waste membranes through physical or chemical means to achieve resource circulation and promote the industry's sustainable development.
