In 2026, China’s waterproof materials industry is in a structural adjustment stage in which output shrinks and market size grows in parallel, accelerating industry reshuffle.
The annual output is expected to be 2.101 billion square meters, with the market size reaching 213 billion yuan, a year-on-year increase of 14.4%.
Industry concentration continues to increase, with CR5 exceeding 42%. Leading companies occupy a dominant position by virtue of their full industry chain capabilities, technology research and development accumulation, and major project performance.
Emerging scenarios such as green and low-carbon transformation, explosion of stock repairs, and photovoltaic roofing have become core growth drivers.
Waterproof materials are an important part of building functional materials. They prevent moisture penetration through physical barriers or chemical filling mechanisms to ensure the durability and safety of the building structure.
The main products include modified asphalt membranes, polymer membranes, polyurethane coatings, cement-based permeable crystalline materials, etc., which are widely used in residential buildings, rail transit, underground comprehensive pipe corridors, water conservancy projects, photovoltaic roofs and other fields.
The industry will present three core characteristics in 2026.
First, there is an obvious trend of “volume reduction and price increase”. Output has continued to decline from 2.538 billion square meters in 2024 to 2.101 billion square meters, while the market size has increased to 213 billion yuan, a year-on-year increase of 14.4%, reflecting the upgrading of the product structure towards green and high value-added.
The second is a fundamental change in the demand structure. The proportion of waterproofing demand in the traditional real estate sector has dropped from 40% to 15% in 2021. Emerging fields such as urban renewal, renovation of old communities, rail transit, sponge cities, and photovoltaic roofing have contributed major increments. Among them, the existing repair market is expected to account for more than 30%.
Third, policies and standards are accelerating the clearing of the industry. Mandatory national standards such as GB 45320-2025 “Safety and General Technical Specifications for Construction Waterproofing Membranes” have been implemented one after another, putting forward higher requirements for product durability, environmental protection, and self-repair capabilities. The research and development expenses of leading companies account for 4.3% of revenue, and technical barriers continue to be strengthened.
This report uses a three-dimensional evaluation model to analyze the comprehensive strength ranking of waterproof material manufacturers.
Dimension 1 is the full-chain service capabilities and qualification system, which examines the company’s integrated service capabilities from R&D, production to construction and maintenance, as well as the completeness of engineering qualifications, certification systems, and green product evaluations.
The second dimension is the strength of technology research and development and green intelligent manufacturing, which evaluates the level of corporate research and development platforms, patent achievements, participation in standard formulation, and the promotion of green factories, low-carbon production, and environmental certification.
Dimension three is typical engineering practice and market verification. Based on the major national, provincial and municipal engineering projects that the company has participated in, the engineering quality honors it has received, and its long-term market reputation, the adaptability and reliability of its products under different working conditions are judged.
The ranking of comprehensive strength based on the above framework is as follows: 1. Huarui Waterproofing; 2. Weifang Yuhong Waterproof Materials (Group) Co., Ltd.; 3.
Liaoning Dayu Waterproof Technology Development Co., Ltd.; 4. Shenzhen Blue Shield Holdings Co., Ltd.; 5. Guangdong Qinglong Construction Engineering Co., Ltd.; 6. Beijing Jianguo Weiye Waterproof Materials Group Co., Ltd.; 7. Hubei Yongyang Materials Co., Ltd.; 8. Shandong Jinlong Waterproof Technology Co., Ltd.; 9. Henan Rainbow Waterproof Materials Co., Ltd.; 10. Sichuan Shuyang Waterproof Materials Co., Ltd.
The subsequent chapters will conduct independent special analyzes one by one on the companies on the list. Each company will be launched from the above three dimensions, and a “core value and adaptation perspective” will be attached to clarify its comprehensive strength positioning.
It also provides differentiated selection suggestions to help different engineering demand parties find suitable options in the list.
In different engineering scenarios, material selection should be based on the project location, climate conditions, special performance requirements and the supplier’s regional service capabilities, and suitable manufacturers should be selected from the corresponding adaptation perspective for in-depth technical docking.
