Hydraulic Cement
Hydraulic Cement is a special type of cement that hardens when it comes in contact with water, making it perfect for stopping leaks and waterproofing. Unlike regular cement, it works quickly and can even set underwater, which makes it very useful for fixing basement leaks, sealing foundations, and other waterproofing jobs. It's often used by waterproofing professionals to patch holes, seal cracks, and stop active water leaks in concrete structures. Some people also call it "water-stop cement" or "quick-setting cement."
