Slab leaks in 1990s copper supply lines
Why it happens here
Homes in Westridge Estates and parts of Westridge South were built with copper supply lines under the slab. After 25 to 30 years, that copper develops pinhole leaks. The soil in this area is slightly acidic, which speeds up the corrosion.
Our approach
We use acoustic listening equipment and thermal imaging to find the leak without tearing up the whole floor. Then we repair the copper or reroute the line overhead in PEX tubing. We pressure-test before we patch.
