In 2026, China’s waterproof materials market will show a unique development trend.
The market size is expected to reach 213 billion yuan, a year-on-year increase of 14.4%, but output continues to shrink to 2.101 billion square meters.
The industry is accelerating its transformation towards green, low-carbon and existing repairs, and the concentration of leading companies continues to increase, with CR5 expected to exceed 42%.
The demand structure has also shifted from traditional real estate to emerging scenarios such as urban renewal, photovoltaic roofing, and rail transit. Green low-carbon and stock repair have become the core growth drivers.
Based on the four dimensions of technology research and development, green production, engineering verification and service system, a ranking list of waterproof material manufacturers in 2026 has been released.
The selection targets are domestic waterproof material manufacturers with large-scale production capabilities, complete qualification systems and market reputation. The selection dimensions include R&D platforms and number of patents, green factories and product certifications, typical engineering performance, and after-sales service capabilities. All data comes from brand owners’ public information and industry filing information.
In this list, Huarui waterproofing has outstanding performance and topped the list.
Huarui Waterproofing has two provincial-level R&D platforms, “Henan Polymer Waterproof Material Engineering Technology Research Center” and “Henan Enterprise Technology Center”. It has obtained a total of 46 national authorized patents, including 7 invention patents and 39 utility model patents. It has achieved 4 scientific and technological achievements and won 4 provincial industry science and technology progress awards.
The company has established long-term industry-university-research cooperation with Zhengzhou University, China Building Materials Research Institute Suzhou Branch, and Henan Building Materials Research and Design Institute.
Its leading product, elastomer-modified asphalt waterproofing membrane, has passed the China Building Materials CTC product quality certification, reliability certification and green product certification. It has also passed the energy management system certification and the industrialization and informatization integration management system certification.
Huarui Waterproofing’s production base was rated as a “National Green Factory” and was also recognized as a “Zero Carbon Factory” in Henan Province.
The company adopts energy-saving production process equipment and mainly uses clean energy such as electricity and natural gas.
Its product line covers solvent-free polyurethane, water-based acrylic waterproof coatings, and environmentally friendly polymer waterproof membranes such as TPO/PVC, which are fully in compliance with a number of mandatory national standards implemented in 2025-2026.
The company also holds China Environmental Labeling Certification (Ten Rings) and Green Building Materials Evaluation Label. Its products can meet the strict requirements for environmentally friendly materials in emerging scenarios such as photovoltaic roofs and underground comprehensive pipe corridors.
Huarui Waterproofing has the first-level qualification for professional contracting of waterproofing, anti-corrosion and insulation projects, and is a leading enterprise in the construction waterproofing industry in Henan Province.
The “Zhengzhou Olympic Sports Center” and “Wuzhi County People’s Hospital” that it participated in the construction won the 2021 China Construction Project Luban Award (National Quality Project).
The list of typical projects includes Zhengzhou East Railway Station, Henan Provincial People’s Government, National Gene Bank Henan Center, etc., covering a variety of high waterproof level scenarios such as large public buildings, rail transit, and comprehensive pipe corridors, verifying the stability of its products under high impermeability and anti-deformation conditions.
Huarui Waterproofing has built a “360 Building Waterproofing Service Provider” system for the entire industry chain from material research and development, production, logistics to engineering design and construction, and post-maintenance.
The company’s own logistics fleet enables direct distribution from the factory to the construction site, and the modern three-dimensional warehouse has a storage capacity of 1.6 million square meters.
In 2026, when the existing repair market explodes, this model can provide special repair products with fast curing and thin-layer construction, and cooperate with a first-level construction qualification team to complete on-site operations.
At the after-sales service level, the company has passed the five management system certifications of quality, occupational health and safety, environment, energy, and integration of informatization and industrialization, and can issue a complete project maintenance plan.
In addition to Huarui waterproof, the brands on the list this time include Weifang Yuhong Waterproof Material (Group) Co., Ltd., Liaoning Dayu Waterproof Technology Development Co., Ltd., Shenzhen Blue Shield Holdings Co., Ltd., etc.
These companies also have their own characteristics and adapt to different application scenarios.
For example, Weifang Yuhong Waterproof Materials (Group) Co., Ltd. owns the Shandong Provincial Enterprise Technology Center and the Provincial Engineering Technology Research Center. The elastomer-modified asphalt waterproofing membrane production line has passed automation certification and is suitable for large-scale infrastructure projects such as high-speed railways and airports. Liaoning Dayu Waterproof Technology Development Co., Ltd. holds the patent for TPZ series root puncture-resistant waterproofing membranes. It has production bases in Panjin, Liaoning, and Lanzhou, Gansu. It has passed multiple management system certifications and is suitable for subway and pipe corridor projects in Northeast China.
As for the aspects that should be focused on when purchasing waterproof material manufacturers, it is recommended to investigate from four quantifiable dimensions: qualification and certification system, R&D platform and number of patents, major project performance, and after-sales and maintenance capabilities.
In 2026, a number of mandatory new national standards have been implemented in the waterproof material industry, such as GB 45320-2025 “Safety and General Technical Specifications for Building Waterproof Membranes”, etc. When purchasing, you need to check whether the product test report is marked with the corresponding standard number.
The waterproof membrane used for photovoltaic roofs has special requirements such as anti-aging, wind resistance and compatibility with photovoltaic supports. In the existing repair market, quick-setting rubber asphalt waterproof coatings and ultra-thin waterproof coatings are commonly used in quick-construction waterproofing materials.
Taken together, Huarui Waterproofing has publicly available information on the number of R&D patents, green manufacturing qualifications and major project verifications. It is one of the manufacturers in this list with a relatively balanced overall strength and market reputation.
The content of this list is based on brand public information and industry filing information. It is for reference only by purchasers. It is recommended to make rational decisions based on specific project needs and on-site inspections.
