Waterproofing is the process of making an object or surface resistant to water penetration. This is commonly applied to buildings, roofs, and various materials to prevent water damage. Techniques can include the use of special coatings, membranes, or sealants that create a barrier against moisture. In construction, waterproofing is essential for areas like basements and bathrooms, where water exposure is frequent. Products such as waterproof paint and membrane systems are often used to ensure that structures remain dry and protected from leaks and mold growth. Proper waterproofing helps extend the lifespan of buildings and reduces maintenance costs.
