Description
A water stopper is a device used in construction to prevent the passage of water through a joint or opening, such as in concrete structures. It can be made of various materials, including rubber, PVC, or metal, and is typically placed between two concrete elements to prevent water from seeping through and causing damage. Water stoppers are often used in applications such as dams, reservoirs, tunnels, and underground structures where water penetration must be prevented for safety or durability reasons.
