A center bulb PVC water stopper is a type of water stop used in construction to provide a water-tight seal in joints and expansion or construction joints. The center bulb design is a common feature in certain types of water stoppers, offering specific benefits in preventing water ingress. Here are some common uses and features of center bulb PVC water stoppers:   1. **Construction Joints:**    - Center bulb PVC water stoppers are often used in construction joints where two concrete structures meet. These joints are prone to water penetration, and the water stopper helps prevent leakage and seepage.   2. **Expansion Joints:**    - In structures that experience thermal expansion and contraction, such as bridges or large concrete structures, expansion joints are installed. Center bulb PVC water stoppers are placed in these joints to accommodate movement while maintaining a water-tight seal.   3. **Basement Construction:**    - During the construction of basements or below-grade structures, water stoppers are crucial to prevent water from entering the structure. Center bulb PVC water stoppers are effective in sealing joints in these applications.   4. **Water Retaining Structures:**    - Structures like reservoirs, water tanks, and swimming pools often use water stoppers to prevent water leakage. Center bulb PVC water stoppers are suitable for these applications due to their flexibility and water-sealing properties.   5. **Tunnels and Subway Construction:**    - In underground constructions like tunnels or subway systems, where water pressure may be a concern, water stoppers are employed. Center bulb PVC water stoppers help maintain a watertight seal even under pressure.   6. **Swimming Pools and Water Features:**    - For the construction of swimming pools and decorative water features, water stoppers are used to prevent water from seeping into surrounding structures. Center bulb PVC water stoppers can accommodate the dynamic conditions in these environments.   7. **Dams and Canals:**    - Water stoppers play a critical role in dams and canals to control water flow and prevent seepage. The flexibility and durability of PVC water stoppers make them suitable for these large-scale projects.   8. **Road and Bridge Construction:**    - In road construction, particularly in bridges and overpasses, water stoppers are used to maintain the integrity of the structures. Center bulb PVC water stoppers help in creating a secure barrier against water infiltration.   Center bulb PVC water stoppers are designed to accommodate movement and deformation in joints while maintaining an effective water seal. Their flexibility, durability, and resistance to chemicals make them a popular choice in various construction projects where preventing water ingress is crucial.PVC water stoppers are specialized construction materials used to prevent water from penetrating through joints in concrete structures. Here's how they are commonly used:   1. **Construction Joints**: PVC water stoppers are installed at construction joints in concrete structures such as basements, retaining walls, swimming pools, dams, and water tanks. These joints are vulnerable points where water can seep through, leading to leaks and structural damage.   2. **Expansion Joints**: In large concrete structures where thermal expansion and contraction occur, PVC water stoppers are used to seal expansion joints. These joints accommodate movement caused by temperature changes, preventing water ingress and maintaining the integrity of the structure.   3. **Joint Sealing**: PVC water stoppers are inserted into the joint gap between adjacent concrete sections before pouring concrete. They act as a barrier, preventing water from infiltrating the joint and causing deterioration over time.   4. **Waterproofing**: PVC water stoppers are integral components of waterproofing systems in concrete construction. By effectively sealing joints and expansion points, they help create a watertight barrier, prev
