"If a building is the skeleton of a city, then waterproofing is the vascular system that keeps the structure functioning." This statement by Liu Li, General Manager of Hubei Yunuo Waterproofing Engineering Co., Ltd., has become widely quoted by professionals in the construction industry. As both a practitioner and a catalyst for transformation, Liu Li has, over the past seven years, led her company from a local contractor to a regional benchmark enterprise. More importantly, through her distinctive management philosophy and engineering acumen, she has advanced the standardization and systematization of China's waterproofing sector.

Since assuming the role of general manager at Hubei Yunuo in 2018, Liu Li has overseen the company's expansion into a leading force in the central China waterproofing market. Under her leadership, the company has achieved over 30 million yuan in annual revenue and delivered services across several key municipal and provincial projects. These achievements are the direct result of her deep insight into industry dynamics and her multidimensional management approach.

"Waterproofing is often the most easily overlooked yet the most consequential part of the entire building process," Ms. Liu Li noted in an interview. She pointed out that due to its "invisible" nature, waterproofing is frequently marginalized during construction planning and execution. To address this, she has focused on three priorities: establishing a standardized construction system, optimizing project execution workflows, and reshaping the industry's perception of waterproofing as a critical trade.

Her philosophy of "systematic management" was first implemented in the Xiangyang Public Sports Center project, a complex development with expansive structures and demanding waterproofing requirements. Liu Li personally participated in the zoning of waterproofing sections, promoted an on-site digital collaboration framework, and introduced tiered supervision for material entry and inspection. These measures ensured that all waterproofing phases were completed within a compressed schedule without a single incident of rework or leakage. The project's success laid the foundation for Yunuo's reputation as a company known for precision, discipline, and reliability.

In large-scale civic projects such as the Hannan Fitness Center and the China Auto Valley Brand Operation Center, Ms. Liu Li pioneered the integrated evaluation of waterproofing materials alongside structural energy efficiency parameters. By optimizing the thickness and configuration of the material layers, she improved thermal stability and durability for both roofing and underground areas—effectively reducing long-term maintenance needs. As she emphasized, "Waterproofing is not an isolated trade, but a systemic element that interlinks with every phase of a building's lifecycle."

Beyond her presence at construction sites, Liu Li has also spearheaded innovation in internal processes and organizational structure. She introduced a dual-reporting system that integrates project manager accountability with technical oversight, enabling simultaneous improvements in quality control and scheduling efficiency. On the talent development front, Ms. Liu Li advocated for cultivating "technically and managerially hybrid professionals," encouraging skilled laborers to transition into supervisory roles and addressing the prevalent gap between technical proficiency and organizational management in the industry.

In 2023, Yunuo successfully delivered several milestone projects, including multiple sections of the Pan-Semiconductor Industrial Park and the Yuhu Cold Chain Logistics Hub in Xiangyang. Confronted with tight deadlines and high technical complexity, Liu Li implemented a modular dispatching model and a joint review mechanism for key milestones. These measures created a three-tiered quality assurance system—covering blueprint review, material inspection, and final delivery—which significantly reduced coordination errors on construction sites. "Waterproofing isn't just about applying a layer of material," she insists. "It's a form of deep structural engagement with the very logic of a building."

Ms. Liu Li also places strong emphasis on the convergence of waterproofing with information technology. She stresses that digitalization and standardization are the only viable paths for the industry to move beyond its workshop-style origins. Looking ahead, she predicts: "The integration of high-performance materials with intelligent construction systems will be the core driver of upgrading the entire waterproofing value chain."

Under her leadership, Hubei Yunuo has maintained a 100% contract fulfillment rate and zero accident record for consecutive years. The company has received numerous letters of commendation from clients involved in major infrastructure projects. In 2024, Yunuo reached a new milestone, winning bids worth over 11.31 million yuan—further cementing its standing in the field.

From the construction site to the industry stage, from managing complex projects to refining enterprise strategy, Liu Li continues to expand the depth and breadth of the waterproofing industry through systematic thinking and firm execution. Her professional journey not only reflects the evolution of a modern enterprise leader but also serves as a representative case study of China's push toward a more specialized and systematized waterproofing sector.

"Making the invisible visible—that is the shared responsibility of our generation of builders," Liu Li concludes.
