Basement waterproofing refers to the process of preventing water from seeping into the basement of a building. There are several different terms that can be used as synonyms for this process, including cellar waterproofing, foundation waterproofing, and damp proofing. Each of these terms refers to a similar process, which generally involves coating the walls and floors of the basement with a waterproof sealant, and installing a drainage system to channel water away from the building. Regardless of the specific term used, basement waterproofing is an important step in protecting a home or building from water damage, mold and mildew growth, and other potential hazards.
