A PVC Water Stopper Seal 300mm is a broad-profile water sealing strip designed to prevent water leakage through construction and expansion joints in concrete structures. The 300 mm width indicates it's meant for heavy-duty or high-pressure water environments, such as dams, tunnels, water treatment plants, and large basements.
