Slab leaks under historic downtown floors
Why it happens here
Copper supply lines under concrete slabs corrode over decades, and the soil movement near the river accelerates it. Once a pinhole opens, water runs silently under the floor until the damage shows up as a warped floor or a high water bill.
Our approach
We use leak detection equipment and pressure isolation to pinpoint the break, then open the smallest possible section of floor. We replace the failed copper with new pipe and pressure-test it before we patch the concrete.
