Product Description

The Damtite Waterproofing Hydraulic Cement is a fast-setting, high-strength repair solution designed to stop active water leaks and seal cracks in concrete and masonry surfaces. This non-shrink, waterproof mortar is ideal for both emergency and permanent repairs in areas exposed to water pressure. It sets in 3 to 5 minutes, even under water, making it perfect for swimming pools, water tanks, and other wet environments.

Simply mix with water to a putty-like consistency and apply with a trowel or putty knife. Once cured, it expands slightly to create a permanent, high-strength patch that will not shrink, oxidize, or corrode. Suitable for interior and exterior applications, above or below grade.
