Dampproofing is a protective treatment applied to building surfaces to prevent moisture from passing through walls and foundations. It's different from waterproofing, though they're often mentioned together. Think of dampproofing as a lighter protective coating that helps buildings resist moisture under normal conditions, while waterproofing provides complete water blockage. Construction companies use dampproofing on foundation walls, basements, and other areas where moisture control is important but full waterproofing isn't required. It's like applying a raincoat to a building - it keeps the moisture out but isn't designed for constant water exposure.
