- **Center Bulb Type**: These have a central bulb and are used in areas with limited movement.

3. **Installation**: PVC water stoppers are typically installed by embedding them into the fresh concrete at the desired location. They are placed so that they create a continuous barrier against water penetration when the concrete cures and hardens. Proper installation is essential to ensure an effective water seal.

4. **Advantages**:

- PVC water stoppers are resistant to water and chemicals, making them suitable for a wide range of applications, including in sewage treatment plants, dams, reservoirs, and basements.

- They are flexible, allowing them to accommodate movement and settlement in the concrete without losing their sealing properties.

- PVC water stoppers are durable and have a long service life.

5. **Maintenance**: Once installed correctly, PVC water stoppers require minimal maintenance. Regular inspections may be necessary to ensure that they remain in good condition and are effectively sealing the joints.

6. **Compatibility**: PVC water stoppers are compatible with concrete and do not corrode or react with it. They are also compatible with a variety of construction materials, making them versatile for use in different projects.

7. **Environmental Considerations**: PVC is a plastic material, and its use has raised environmental concerns due to issues associated with its production and disposal. Efforts have been made to develop more environmentally friendly alternatives in some cases.

PVC water stoppers are crucial components in many construction projects, especially in situations where waterproofing is essential. Proper selection and installation of the appropriate type of PVC water stopper can help ensure the integrity and longevity of concrete structures while preventing water infiltration.
