As a leading beverage enterprise in China, Nongfu Spring continues to improve its national industrial layout and build a modern production base with high standards and high quality. Among them, the Haikou Water Source Factory is the 17th largest water source in the country for the brand, with a total investment of about 1.5 billion yuan. It is the core strategic layout for Nongfu Spring to deeply cultivate the South China market; The second phase of Guizhou Jiangkou Production Base is a comprehensive industrial park integrating modern production and industrial tourism, with extremely strict standards for construction technology and engineering quality.
OSEA Guard Waterproofing, with its strong product strength and mature industrial waterproofing system solutions, has successfully become one of the two key project roof waterproofing service providers. With high-end polymer waterproofing technology, it has built stable, long-lasting, and safe professional waterproof barriers for the steel structure roofs of Haikou Volcano Beverage Production Base and Guizhou Jiangkou Production Base Phase II Project.
The stability, safety, and durability requirements for waterproofing systems in food industry factory buildings far exceed those of ordinary buildings. Especially for steel structure roofs, which are exposed to natural environmental erosion for a long time, they are highly susceptible to factors such as temperature fluctuations, strong winds and rainfall, and structural micro deformations, posing a high challenge to waterproof materials and construction techniques.
There are significant differences in geographical environment and climate conditions between Haikou and Jiangkou. In order to accurately adapt to the working conditions of the two projects, OSEA Guard has tailored its exclusive waterproofing solution based on 1.5mm-PVC waterproofing membrane, targeting different regions to solve waterproofing problems.
Haikou is located in a tropical monsoon climate zone, with high temperatures and humidity throughout the year and abundant rainfall. It has extremely high requirements for waterproof materials to have high resistance to moisture and water seepage; Jiangkou, Guizhou is located at the edge of the Yunnan-Guizhou Plateau, with large temperature difference between day and night and high humidity in four seasons, which is very easy to cause aging, cracking and delamination of waterproof layer. OSEA GuardPVC waterproofing membrane has excellent low-temperature flexibility and super dimensional stability, suitable for complex climate environments in two places, effectively buffering the deformation pressure of steel structure roofs, and eliminating hidden dangers such as waterproof layer tearing and damage from the root.
Types of PVC coil products
Ultra long weather resistance and service life: excellent heat aging resistance and UV resistance, can be directly exposed for use.
Excellent aging resistance: after special processing, it has high UV resistance and aging resistance.
Excellent welding performance: The coil material is welded with hot air, resulting in high seam peeling strength; Long term weldability and easy repair.
Excellent chemical resistance: It has strong stability against chemicals such as acid, alkali, and salt, is not easily corroded by chemicals, and can maintain its waterproof performance for a long time.
Multiple colors: Provides a variety of color options in addition to regular light colors to beautify the environment.
High waterproof reliability: The high-density physical structure can effectively prevent moisture infiltration. Its surface is smooth and flat, with good impermeability, and moisture cannot enter the interior of the building through its surface.
In terms of construction technology, the project adopts high-precision hot air welding technology throughout the entire process, with extremely strong overall sealing. The product has excellent aging resistance, corrosion resistance, and weather resistance, which can maintain the integrity and stability of the waterproof layer for a long time, fully adapt to the long-term, safe, and high standard operation needs of food production plants, and firmly safeguard the building safety bottom line of national drinking water projects.
The two major Nongfu Spring production bases are both key industrial projects with high standards and specifications. The construction process adheres to the quality concept of continuous improvement, and has strict screening standards for the brand strength, product performance, and landing services of supporting building materials. OSEA Guard is able to serve two core bases simultaneously, which is a dual high recognition of the company's technological strength, product quality, and comprehensive service capabilities by top national brands.
As an innovative enterprise deeply rooted in the field of polymer waterproofing for many years, OSEA Guard has always been driven by technological innovation, continuously iterating and upgrading industrial waterproofing system products. Our PVC waterproofing membrane strictly complies with national industry standards and has undergone multiple performance optimizations to adapt to complex working conditions of various industrial steel structure roofs. It has outstanding advantages in stability, weather resistance, and practicality, and is widely used in various high standard industrial buildings, livelihood projects, and benchmark industrial park projects.
The landing of two benchmark projects in Nongfu Spring once again confirms the professional position of OSEA Guard in the field of food industry waterproofing, further consolidating the brand's benchmark influence in the high-end industrial waterproofing track.
In the future, OSEA Guard will continue to deeply cultivate the field of building waterproofing, adhere to craftsmanship and quality, and deeply cultivate technological innovation. With higher quality products, more professional system solutions, and more comprehensive landing services, OSEA Guard will empower more national level benchmark engineering construction, safeguard the long-term safety of buildings with polymer waterproofing technology, and assist in the high-quality development of various industries.
