Slab leaks in copper supply lines
Why it happens here
Copper lines under Longneedle slabs are now 25 to 30 years old. The soil here shifts slightly with moisture, and that movement stresses the pipe until a pinhole opens. Hot water lines fail first because heat accelerates the corrosion.
Our approach
We use acoustic and thermal leak detection to find the exact spot before we cut concrete. Then we open a small access, replace the failed section, and pressure test. Most Longneedle slab repairs are done in a single day.
