Fairmate Waterplug is a fast-setting hydraulic compound that stops running water instantly by setting under water within 1 to 3 minutes. It is non-shrinking and nonmetallic with high structural strength, making it suitable for plugging leaks through concrete, masonry, dams, pipes and wall/floor junctions. Fairmate Waterplug minimizes the risk of thermal cracking and is packaged in 1kg, 5kg and 25kg bags for easy application.
