Slab leaks under slab-on-grade foundations
Why it happens here
Copper lines under Stoney Creek slabs have been under constant pressure and soil contact for decades. Slightly aggressive water chemistry and soil movement cause pinholes that grow. The leak travels under the slab, so the surface symptom rarely lines up with the break.
Our approach
We pinpoint the leak with acoustic and thermal equipment before any concrete is cut. Then we either repair the line in place or reroute it overhead through the attic with PEX, which avoids slab work entirely and is often the better long-term fix.
