PVC External Waterstop with Valve is a type of waterstop used in construction to prevent water from penetrating through the construction joint between two concrete elements, such as walls or slabs. It is installed on the outer surface of the concrete and is made of durable PVC material, which is resistant to various weather conditions and chemicals.
The valve feature allows for easy flushing and testing of the joint seal. When the joint is being flushed or tested, the valve is opened to allow water to flow through the joint, and when the test is completed, the valve is closed to maintain the joint seal. This type of waterstop is commonly used in below-grade construction such as basements, tunnels, and water treatment facilities.
