dampproofing
Stopping water penetration
Dampproofing is the application of materials or treatments to prevent moisture from penetrating walls, floors, or foundations.
Unlike waterproofing, which blocks liquid water under pressure, dampproofing addresses water vapor and minor seepage: The contractor recommended dampproofing the basement walls before finishing.
Common methods include asphalt coatings, plastic sheeting, and specialized membranes.
