High-performance centrally embedded water barriers are pre-installed in the middle of concrete joints. Optimized for withstanding extreme hydraulic pressure, they coordinate well with concrete deformation, permanently prevent joint leakage, and guarantee structural safety and impermeability of water conservancy, tunnel and underground engineering.
High-performance externally fitted waterstops are affixed to the outer face of concrete joints. Engineered to resist severe hydraulic pressure, they accommodate differential deformation of concrete components, permanently intercept joint seepage, and secure structural stability and impermeability for municipal, basement and pipeline projects.
High-performance water-swellable sealing strips for concrete joints expand upon water contact to block seepage, withstand high hydraulic pressure and maintain long-term waterproof performance of municipal and hydraulic projects.
These are the products we recommend to you. of course, we provide customized services
SO Series PVC waterstop is an internal expansion joint waterstop for reinforced concrete structures where a continuous watertight barrier is required across movement joints. The center-bulb profile is embedded centrally within the concrete pour and flexes to accommodate expansion, contraction, and shear displacement along the joint line.
DV Series PVC Waterstop is a dumbbell-profile internal construction joint waterstop used in reinforced concrete structures where a continuous watertight seal is needed across movement joints.
DR Series PVC Waterstop is an external expansion joint waterstop designed for the exposed face of concrete structures where movement joints must remain watertight.
Founded in 2002, Foshan Nanhai FUFUJING Plastic & Hardware Co., Ltd. has grown into a world-class leader in concrete joint waterproofing solutions. We specialize in the R&D and manufacturing of high-performance middle-set (internal) and external PVC waterstops.

To provide the best factory price, please specify the profile type (Internal/Middle-set or External/Rearguard), geometric shape (Dumbbell, Center Bulb, or Flat Ribbed), dimensions (width $\times$ thickness, e.g., $250\text{mm} \times 8\text{mm}$), and your total order volume in meters. If your project has specific engineering blueprints or requires custom OEM profiles, enclosing your technical drawings will allow our senior engineers to deliver a precise quote within 24 hours.
FUFUJING (Foshan Nanhai Fufujing Plastic & Hardware Co., Ltd.) is a direct, specialized manufacturer with over 20 years of industrial extrusion experience since 2002. Our fully equipped manufacturing facility is located in the Yongkou Industrial Zone, Nanhai District, Foshan, Guangdong. By sourcing directly from our factory, you eliminate middleman markups, gain flexible OEM/ODM customization capabilities, and receive direct technical support from our engineering team.
For our standard catalog profiles (such as standard DB dumbbell or center-bulb series), the Minimum Order Quantity is highly flexible, typically starting from 100 rolls or a minor trial volume depending on raw material stock. For completely custom profiles requiring unique mold development, the MOQ varies based on cross-sectional weight. Please contact our sales team to discuss your specific infrastructure project needs.
FUFUJING PVC waterstops are extruded from premium, non-toxic vinyl compounds that offer vastly superior thermoplastic welding capabilities compared to rubber. While rubber requires complex vulcanization chemicals and heavy on-site splicing equipment, our PVC profiles can be seamlessly heat-welded on-site in minutes using a professional Waterstop Heater Blade and Jointing Jig, creating a continuous, leak-proof matrix with far greater resistance to ozone, chlorinated water, and acids.
Quality is our baseline. FUFUJING is an ISO 9001 certified factory. All our concrete joint waterproofing products undergo rigorous laboratory testing to ensure excellent physical properties that meet or exceed international specifications (such as ASTM and BS standards). Our high-grade PVC material exhibits a tensile strength of $\ge 14\text{ MPa}$ and elongation at break of $\ge 320\%$, making them perfectly suitable for high-pressure environments like dams, tunnels, reservoirs, and basements.
We can provide high-quality customized solutions, ensuring every step is precise, efficient, and satisfactory.
