Foundation Repair questions, answered by experts

New constructions need time to “settle” and sometimes, small hairline cracks occur as a result. Larger horizontal or “stair step” cracks, however, are usually a sign of a deeper, more severe issue. It could indicate an issue with the soil beneath the home, a problem caused by an overgrown tree, or another problem.

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

Underpinning a foundation is when a contractor installs deep piers under your foundation to provide support. Professionals often use this foundation repair method when the soil underneath the foundation is no longer strong enough to support the house evenly. Underpinning a foundation often comes with other repairs to tackle the source of the problem. For example, a contractor may regrade your yard around your home’s foundation to make sure water drains away from your house.
