Landscaping Problems that Lead to Basement and Crawl Space Water Damage

Basement and crawl space water damage can originate from both indoor and outdoor sources. Because they’re the lowest point in the house, basements and crawl spaces are often the final destination of water that leaks anywhere else inside the home. Rising groundwater from the soil beneath the house provides another source of basement and crawl space water damage. One of the major outdoor factors that promotes water intrusion at these lowest levels, however, is the landscaping surrounding the home. Water runs downhill and always follows the path of least resistance. These two facts dictate that the landscaping around your house either helps keep your basement and crawl space dry—or greatly contributes to water damage in those areas. Here are some things to do to make sure your landscaping isn’t working against you:

  • The grade of the landscape surrounding your home should be sloped away from the house so that water flows away from the foundation or crawl space. For the first four feet, the soil should slope downward about six inches to form a mini-berm that diverts water away and prevents pooling near the foundation or basement walls. Extending out into the yard, the slope can be more gentle, but there should be no areas of ground that slope toward the house.
  • If you are altering the landscape, always use clean, dense fill dirt for the area adjacent to the house—not topsoil. Porous topsoil provides little resistance to water soaking into the ground around the foundation, which then infiltrates through cracks in basement walls.
  • Flower beds next to the house may also promote basement and crawl space water damage. Beds generally comprise a large surface area of exposed, porous soil, readily absorbing water that then flows downward along the basement wall. Edgings around flower beds also cause water to pool, increasing ground absorption and infiltration into the house. Instead of flower beds immediately beside the house, landscaping with grass or other dense ground cover is recommended.
