Slab leaks are similar to hidden water pipe leaks. In some cases, you won’t know you have this problem until significant damage has already occurred. Slab leaks occur when the cement in your foundation starts to crack, bubble, or bend. The two main causes are water line leaks and sewer line leaks.

Old, corroded pipes are often prone to developing leaks. When a water line leak occurs under your home’s foundation, you have a slab leak. If not addressed in time, the leak can cause the soil surrounding the water line to shift away from the slab foundation resulting in structural damage.

What Causes Slab Leaks?

Some homes were built with plumbing materials that are now considered outdated.

  1. Cast iron pipe was used in homes built prior to the 1960’s. Unprotected cast iron service lines can be corroded by water and minerals in the soil.
  2. Galvanized steel pipes were common in homes through the 1950’s and are susceptible to corrosion and clogging.
  3. Clay pipes were used until about 1975 and can be prone to breaking or cracking.

How To Detect Slab Leaks:

  1. A spike in your water bill, yet your water use has not gone up
  2. The sound of constantly running water with low water pressure
  3. Damp spots on the floor with no obvious reason for them
  4. Your water heater continuing to run without stopping
  5. Noticeable cracks in your home’s foundation

If you have a slab leak, precision equipment is necessary to detect the leak, which usually involves excavation to reach the pipes. The narrower the digging area, the less damage the plumber will need to repair or replace the pipes.

If you do suspect you have a slab leak, the most important thing you can do is shut off your water, then call a licensed plumber to get the repair work underway.
