Waterproofing is the process of making a material or structure resistant to water penetration. This is commonly applied to buildings, roofs, and basements to prevent water damage from rain, flooding, or leaks. Various methods and materials, such as membranes, coatings, and sealants, are used to create a barrier against moisture. In addition to construction, waterproofing is also important in products like watches, clothing, and electronics. These items are designed to withstand exposure to water, ensuring their functionality and longevity. Proper waterproofing helps maintain the integrity of structures and products, reducing the risk of damage and costly repairs.
