What’s Under the House: Fill Dirt and Moisture Issues

Filed in Legal by on July 14, 2021 1 Comment

A new home foundationWhen placed under a foundation, fill dirt is arguably the most important structural component of a home, and that fill dirt is the leading cause of new home structural failures.

Walt Keaveny, a professional engineer and geoscientist for 2-10 Home Buyers Warranty, explores fill dirt and offers tips for minimizing problems in a new NAHB Construction Liability resource, Let’s Talk Dirt.

According to Keaveny, not only is fill dirt the most common cause of structural failure, it is also a very costly repair – nationwide it costs an average of over $50,000 to investigate and repair a structural failure caused by fill dirt. In some states the average cost exceeds $100,000.

Let’s Talk Dirt provides information about fill placement, density requirements, testing, and the benefits of working with a geotechnical engineer.

Keaveny also explores moisture issues in basements in Ultimate Guide to STOP Basement Water Leaks.

Over half of all basements have some moisture issues, with basement walls and floors the most common locations for water leaks in a home.

Unlike improperly compacted fill dirt, water leaks in basements rarely represent a structural deficiency, according to Keaveny.  However, a water leak that is seen trickling is not normal, and it is beneficial to terminate the source of the water to avoid: (1) saturating soils that support the foundation, (2) rot and degradation of wooden framing, (3) damage to drywall and finishes, (4) damage to household items, (5) mold and (6) vermin.

To learn about the three major sources that cause water leaks, water migration into basements, damp proofing versus water proofing, and to view Keaveny’s Water Source Checklist, review the Ultimate Guide to STOP Basement Water Leaks.

    I’m glad you mentioned checking for water exposure and rot. It looks like there is some rot in some of our walls. I’ll have to have a contractor demolish them and put new ones up.
