SLAB LEAK DETECTION

---

Slab leaks occur when water supply or return lines located beneath a concrete foundation develop a leak. These leaks are often hidden from view and can continue undetected for extended periods, potentially leading to structural damage, flooring issues, and increased water usage.

Mainline Leak Detection provides professional slab leak detection services for residential, commercial, and governmental properties using non-invasive methods designed to accurately locate leaks while minimizing disruption to the structure.

Common Signs of a Slab Leak

• Unexplained increases in water bills

• Warm or damp areas on concrete or flooring

• Cracking or buckling of floors or walls

• Sound of running water when fixtures are off

• Persistent moisture, mildew, or mold odors

• Hot spots on slab foundations

How We Locate Slab Leaks

Our technicians use advanced acoustical listening equipment, pressure testing, and thermal imaging when appropriate to identify the presence of slab leaks. These tools allow us to accurately locate leak sources beneath concrete without unnecessary demolition.

By combining multiple diagnostic methods, we are able to determine the most likely location of a slab leak so repairs can be planned efficiently and with minimal impact to the property.
