It involves excavating around the foundation to expose the walls, repairing any cracks or defects, and applying a waterproof membrane or coating on the outer side of the foundation walls. The process aims to create a barrier that shields the basement from water and maintains a dry living space, preventing water damage and ensuring habitability. Exterior basement waterproofing is crucial for building maintenance, as it safeguards the structural integrity of buildings and avoids expensive repairs.
