Discovering a leaky pipe in your home isn’t great, but it’s better if it’s in a visible spot like under a sink or in the basement with an exposed ceiling. However, leaks in the slab, which is the foundation under your home, are trickier because there are no alarm systems to warn you. Finding these leaks early is crucial as they can lead to serious damage, including issues with the foundation. Since there’s no built-in warning, detecting a slab leak can be challenging, and by the time you notice it, a lot of damage might have already happened. So, it’s important to learn how to detect a water leak under a slab early to prevent significant harm to your home.

What is a Slab Leak?

A slab leak happens when there’s a water leak in the copper pipes under the concrete foundation of your home. If this kind of leak is above ground, like in the wall or ceiling, it’s called a pinhole leak, usually caused by long-term corrosion in copper pipes. Slab leaks can be on the pressure side or drainage side of your foundation. Finding pressure side leaks is easier and can prevent a lot of damage if detected early.

On the drainage side, leaks are harder to notice and can go on for a long time without showing outside signs. Over time, slab leaks can harm hardwood floors, carpets, drywall, and cabinets, potentially leading to mold and fungus issues if not fixed within 24 hours. Regular professional plumbing inspections are essential to catch and repair slab leaks before they cause extensive damage to your home.

Causes a Slab Leak?

Pipes under a concrete slab might start leaking for two main reasons:

  • Pipes made from older materials like cast iron, galvanized steel, or Orangeburg can corrode over time.
  • The ground shifting due to factors like expansive soil, earthquakes, or other disturbances can also lead to leaks.
  • Additionally, tree roots can invade and puncture pipes, emphasizing the importance of considering tree proximity during home construction.
  • Using commercial waste pipe cleaners can damage pipes, underlining the need to hire a certified and experienced plumbing contractor for such tasks.
