Water-proof

To prevent water seepage into the outer wall, it's crucial to take several preventive measures. Start by inspecting the exterior for any cracks or gaps where water could enter. Seal these with waterproof caulking or sealant designed for outdoor use. Ensure that gutters and downspouts are clear and functioning properly to divert rainwater away from the walls. Consider applying a waterproof coating or paint designed for exterior walls. Properly grade the soil around the foundation to ensure that water flows away from the house. Regularly inspect and maintain these measures to protect against water damage and maintain the integrity of your outer walls.
