Cementitious waterproofing is a method used to prevent water from penetrating concrete surfaces. It involves applying a mixture of cement, sand, and special additives that enhance its waterproofing properties. This type of waterproofing is commonly used in areas like basements, swimming pools, and foundations to protect structures from moisture damage. The application process typically includes cleaning the surface, mixing the waterproofing compound, and applying it with a brush or trowel. Once cured, the cementitious layer forms a durable barrier against water. This method is favored for its ease of use and effectiveness in creating a long-lasting seal against water intrusion.
