Basements and crawl spaces are normally damp because they’re located below grade (yard level). But when water—not just moisture—actually seeps through a crack, it poses an increased risk of mold and mildew growth. While the crack should be sealed as described above, it’s even more important to keep water away from the foundation wall. This can be done by removing foundation plantings, installing guttering and downspouts, and adding soil to the yard along the foundation in order to create a two percent or more slope away from the house that allows water to run away from the foundation.

Step 3 - Apply Plastic Sheets
- Lay the plastic sheets from your foundation outward. Attach them with an outdoor adhesive and wait for it to dry; then, place soil over the top. It’s recommended to use soil with a high clay content to prevent water from trickling through.
Step 4 - Deal with The Cracks
- Now that you’ve dealt with the cause of these cracks, the damage itself must be fixed. Go to the basement and look for cracks, then use a wire brush and air pump to clean them. They need to be cleaned before they are mended because dirty cracks will not hold the filling. The material used in the repair will depend on the size of the damage.
