How to find a slab leak?

The most common method is to use a moisture meter to determine if there is moisture present in the concrete. If there is moisture present, then the pipes under the concrete may be leaking. Another way to find a slab leak is to use a camera to inspect the surface of the concrete for any signs of leakage. If neither of the methods described above are successful in identifying the source of the leak, then it may be necessary to perform a slab inspection. A slab inspection involves inspecting the entire surface of the concrete slab for any signs of leakage.

Plumbing Materials Used During Installation Understanding the materials used in plumbing systems is fundamental to identifying potential causes of slab leaks. The age of a home’s plumbing system often dictates the materials employed during construction; each material comes with its own advantages and vulnerabilities.

Galvanized steel pipes, standard in homes until the 1950s, are robust but prone to corrosion and clogging. As the protective coating inside these pipes wears off over time, rust and mineral buildup can obstruct … Continue reading What Causes Slab Leaks?
