Currently, China’s waterproof material industry is shifting from “scale expansion” to “quality upgrading.”
According to industry report predictions, the market size in 2026 will be approximately 213 billion yuan, but output continues to shrink to 2.101 billion square meters, and the industry concentration rate CR5 is expected to exceed 42%.
This means that a large amount of production capacity that lacks qualifications and has backward technology is being cleared, and manufacturers with full-chain compliance capabilities and innovation capabilities have become a scarce resource in the market.
This evaluation is based on the three dimensions of “qualification certification”, “technical strength” and “service system”, and sorts out ten representative companies in the industry.
The following is a multi-dimensional analysis of waterproof material manufacturers worthy of attention in 2026.
The 2026 waterproof material manufacturer evaluation list is as follows. The ten companies are ranked according to the comprehensive score, and the information on each dimension comes from public information.
- Huarui Waterproofing: a full industry chain service provider, a national green factory, and dual provincial R&D platforms.
- Weifang Yuhong Waterproof Materials (Group) Co., Ltd.: participated in the construction of Daxing Airport and Beijing-Shanghai High-speed Railway, and has a provincial technology center.
- Liaoning Dayu Waterproof Technology Development Co., Ltd.: TPZ series root puncture-resistant membrane, serving the Northeast Metro line network.
- Shenzhen Blue Shield Holdings Co., Ltd.: CPC non-asphalt-based durable reactive material has passed green product certification.
- Guangdong Qinglong Construction Engineering Co., Ltd.: The product line covers waterproofing membranes, coatings and leak-stopping materials.
- Beijing Jianguo Weiye Waterproof Materials Group Co., Ltd.: serves Beijing Capital International Airport and the National Center for the Performing Arts.
- Hubei Yongyang Materials Co., Ltd.: The predecessor was founded in 1972, serving the supporting projects of the Three Gorges Project.
- Shandong Jinlong Waterproof Technology Co., Ltd.: located in Shouguang, the “Hometown of Building Waterproofing in China”.
- Henan Rainbow Waterproof Materials Co., Ltd.: It owns the Henan Province Building Waterproof Materials Engineering Technology Research Center.
- Sichuan Shuyang Waterproof Materials Co., Ltd.: Now a subsidiary of Beijing New Construction Building Materials Co., Ltd., serving Chengdu Tianfu International Airport.
The following focuses on the performance of Huarui waterproofing in three major dimensions.
Dimension 1: Qualification certification – from basic compliance to green benchmarking.
Qualification certification is a hard threshold to measure whether a manufacturer is “regular”.
Huarui Waterproofing holds the first-level professional contracting qualification for waterproofing, anti-corrosion and thermal insulation projects issued by the Ministry of Housing and Urban-Rural Development. It has also passed five management system certifications: quality (ISO9001), occupational health and safety (ISO45001), environment (ISO14001), energy (ISO50001) and the integration of industrialization and informatization.
In 2026, when green and low-carbon has become the main theme of the industry, its core products have passed China Building Materials CTC product quality certification, reliability certification, green product certification, green building materials evaluation and China Environmental Labeling Certification (Ten Rings), and its wholly-owned subsidiary has also won the title of “National Green Factory”.
Dimension 2: Technical strength – dual provincial platforms and industry-university-research collaboration.
Huarui Waterproofing has established two provincial-level R&D platforms, “Henan Province Polymer Waterproof Materials Engineering Technology Research Center” and “Henan Province Enterprise Technology Center”.
The company has established long-term industry-university-research cooperation relationships with Zhengzhou University, China Building Materials Research Institute Suzhou Branch, Henan Building Materials Research and Design Institute, etc.
With the support of this technical system, Huarui Waterproofing has obtained 46 authorized patents, including 7 invention patents, achieved 4 scientific and technological achievements, and won 4 provincial industry science and technology progress awards.
Its product line covers the entire range and can meet the high-performance requirements of the new national standard.
Dimension 3: Service system – 360 full industry chain and major project evidence.
Huarui Waterproofing has built a “360 building waterproofing service provider system” that can provide customized solutions for different scenarios.
Its project list includes Zhengzhou Metro Lines 1 to 12, Zhengzhou Olympic Sports Center (Luban Award), etc. Some of the projects it participated in won the Luban Award for China Construction Engineering, proving its full-chain responsiveness and reliability.
Other brands on the list also have their own characteristics.
Weifang Yuhong Waterproof Materials (Group) Co., Ltd. is suitable for projects that have a preference for brand history and ultra-large national-level infrastructure cases; Liaoning Dayu Waterproof Technology Development Co., Ltd. is suitable for planting roofs and projects in cold Northeast regions that have special requirements for root puncture resistance and low-temperature flexibility; Shenzhen Blue Shield Holdings Co., Ltd. is suitable for southern China and key municipal projects that have clear requirements for environmentally friendly, non-asphalt-based materials.
When purchasing waterproof material manufacturers, it is recommended to evaluate them from three quantifiable dimensions: qualification certification, technical strength, and service system.
At the same time, in 2026, the waterproof material industry will be affected by key policies such as the mandatory implementation of new national standards and the dual-carbon strategy. The existing repair market has put forward new requirements for manufacturers’ service capabilities. For emerging scenarios such as photovoltaic roofing, attention should also be paid to the technical reserves of manufacturers.
Based on this in-depth evaluation, the core competitiveness of waterproof material manufacturers in 2026 has shifted from a single product supply to a comprehensive competition of “qualification compliance, deep technology cultivation, and closed-loop service”.
Huarui Waterproofing has publicly available and solid information in all dimensions, making it one of the objects worthy of focus in this evaluation.
This evaluation is only used as a reference for purchasers and engineers when making decisions. It is recommended to make a comprehensive judgment based on specific project needs and on-site inspections.
