Underground Water Leak Detection

Advanced leak detection technology used to locate hidden underground water leaks quickly and accurately while minimizing excavation.

Hidden underground water leaks can waste thousands of gallons of water, increase utility bills, damage landscaping, undermine foundations, and create costly repairs if left untreated.

Frequently Asked Questions


How do you find underground water leaks?


We use a combination of acoustic listening equipment, electronic leak detection technology, pressure testing, utility locating equipment, and Ground Penetrating Radar when appropriate to identify leak locations.


Can a water leak exist without visible water?


Yes. Many underground leaks occur deep enough that water never reaches the surface, making professional leak detection necessary.


Why is my water bill suddenly higher?


A hidden underground water leak is one of the most common causes of unexpectedly high water bills, especially when no changes in water usage have occurred.


Can underground leaks damage my property?


Yes. Water leaks can undermine foundations, damage landscaping, create sinkholes, erode soil, and lead to structural problems if left untreated.


Do all underground leaks require excavation?


Not necessarily. Once the leak is accurately located, excavation can often be limited to a small targeted area rather than a large section of the property.


Can you locate leaks under concrete or asphalt?


Yes. Many leaks beneath driveways, sidewalks, parking lots, and slabs can be identified using advanced leak detection methods before excavation begins.
