7 Warning Signs of an Underground Foundation Slab Leak

A slab leak occurs when subterranean hot or cold copper supply lines buried beneath your concrete foundation rupture. Left undetected, slab leaks undermine foundation footings, cause soil displacement, and result in catastrophic structural damage.

7 Symptoms of an Active Slab Leak

1. Unexplained Hot Spots on Flooring: A hot slab leak warms tile, hardwood, or carpet flooring above the broken line.
2. Sound of Running Water When Faucets Are Closed: Hearing continuous rushing water behind walls or under floors.
3. Spinning Water Meter Indicator: If all home fixtures are shut off and your water meter's low-flow indicator triangle is spinning, water is actively escaping.
4. Sudden Spikes in Water Bills: Unexplained doubling or tripling of monthly utility charges.
5. Damp Flooring & Dome Buckling: Moisture seeping upward through slab cracks, causing laminate warping or tile lifting.
6. Cracks in Foundation & Drywall: Structural shifting caused by soil erosion underneath the foundation.
7. Loss of Water Pressure: Sudden drop in domestic hot or cold line pressure.
