Why uneven moisture matters
If the soil around one side of a house dries more than another side, the foundation can experience different support conditions. Tree roots, shade, irrigation, drainage, and plumbing leaks can all create local differences.
What homeowners can watch
Look for ponding water, downspouts that discharge beside the slab, soil pulling away during dry periods, concentrated irrigation, leaking exterior plumbing, and large trees close enough to influence soil moisture.
Avoid one-size-fits-all fixes
Adding water, installing piers, removing trees, or changing drainage without understanding the actual cause can create new problems. The response should match the property.
