Basement waterproofing is a process designed to prevent water from entering a basement or crawl space. This is important because excess moisture can lead to mold growth, structural damage, and a decrease in property value. Common methods include applying sealants, installing drainage systems, and using sump pumps to manage water levels. There are various techniques for basement waterproofing, such as interior and exterior waterproofing. Interior waterproofing focuses on sealing walls and floors, while exterior waterproofing involves digging around the foundation to apply waterproof membranes. Proper basement waterproofing can enhance the longevity and safety of a home.
