Waterproofing a basement involves improving exterior drainage, installing a sump pump, applying waterproof coatings to walls and floors, and sealing any cracks in the foundation. Proper ventilation helps manage indoor humidity.

To effectively waterproof a basement, start by improving the exterior drainage around the foundation to ensure water is directed away from the home. Install a sump pump in a pit to collect and pump out any water that enters the basement. Apply waterproof coatings or sealants to the basement walls and floors to prevent moisture penetration. Identify and seal any cracks in the foundation to stop leaks. Maintain proper ventilation with dehumidifiers to manage indoor humidity.
