PVC Center Bulb Waterstop

A PVC center bulb waterstop is a waterproof material. It is mainly used in underground projects and water conservation efforts. It achieves a waterproof effect by embedding itself in concrete. Its main features are strong corrosion resistance, easy installation, and high adaptability. This makes it great for many engineering projects, such as reservoirs, tunnels, and basements.

Material and Manufacturing Process

PVC center bulb waterstop comes from polyvinyl chloride resin mixed with additives. They make it using processes like mixing, granulating, and extrusion. This material has great elastic properties. It stops leakage and seepage in concrete expansion and deformation joints. It also has good corrosion resistance and durability.

Application Areas and Installation Methods

PVC center bulb waterstop is commonly used in various projects. You’ll find it in water conservancy work like reservoirs and dams. It’s also used in underground projects such as subways, tunnels, and parking lots. Additionally, municipal projects like streets, bridges, and drainage systems rely on it too. Installing it is simple, but you need to follow some steps. First, treat the base. Then, choose the right connection methods and determine the embedding depth.

Differences from Other Waterstop Strips

The main difference between PVC center bulb waterstop and external PVC waterstop strips lies in their installation locations. External waterstop strips go on the concrete surface. In contrast, the construction team places the PVC center bulb waterstop inside the concrete.
