Post-Tension Slab Leak Detection in Apex
Many newer homes are built on post-tension slabs that use steel cables under high tension. Cutting into one without care is dangerous and can damage the foundation. We locate the cables with scanning equipment before any repair access is opened. This lets us repair the leak without risk or recommend a reroute that avoids the slab entirely.
Thermal Imaging for Slab Leaks in Apex, NC
Thermal imaging cameras allow us to visualize temperature differences on surfaces, which can indicate a hidden water leak. As water escapes a hot water line, it creates a clear thermal signature on the concrete slab. This technique is particularly useful for hot water line leaks and helps us narrow down the search area quickly without any physical disruption to your property in Apex.

Pressure Testing & Isolation in Apex
When a leak is suspected, we can perform pressure tests on individual water lines. By isolating sections of your plumbing system and monitoring pressure gauges, we can confirm the presence of a leak and often determine which specific line is compromised. This step-by-step approach is crucial for homes with complex plumbing layouts, giving you an accurate diagnosis before any excavation in Apex, NC.
