Slab Leaks FAQs

A slab leak doesn’t sound like something you hear of every day, and for some, this may be the first time they’re hearing of it. The concrete foundation beneath your home is referred to as the slab.

A slab leak can cause a lot of damage to the foundation and the rest of your home. Want to know more about slab leak? Here are some FAQs homeowners pose about slab leaks and helpful answers.

What is a Slab Leak?

A cement slab is usually found where a basement or crawl space is absent in a home and functions as the home’s foundation. Usually, several pipes are fitted through this cement slab, and if there is a plumbing leak into the foundation, this is characterized as a slab leak. Water damage could prove significant and costly, whether the leak is caused by a crack in the pipes or a rupture.

What Are the Signs You Have a Slab Leak? 

A slab leak can be quite obvious if the leak is large and is caused by a burst pipe or subtle from a small crack in the pipe. Still, some signs of a slab leak include:

  • A jump in your water bill
  • Noise like water is running when the faucets are off.
  • Foundation cracks
  • Foundation sinking evident from uneven floors

What is the Cause of the Slab Leak?

A few different factors could cause a slab leak in your home. These include:

  • Corrosion of copper pipes due to mineral accumulation from water that passes through the pipes. The corrosion creates holes in the pipes for leaks to occur.
  • Excess pressure on underground pipes can eventually result in them cracking. Clay soils typically expand when wet and contract when dry and these changes can cause the ground beneath the foundation to shift. This can add pressure on the slab and pipes. This shift could also be caused by an earthquake.
