A leaking pipe can cause thousands of dollars in damage to a home and force a homeowner to go through a lengthy repair process. Even worse, if a pipe is located under a concrete slab, it can be difficult to fix. Luckily, if homeowners know how to detect water leaks under concrete, they can stop the leak before it causes serious damage.

Here are some tips on how to find a water leak under a concrete slab to prevent damage.



Know the Signs

There are two types of leaks: a waterline leak and a sewer leak. Both of these types of leaks can cause longterm damage, so it’s important for a homeowner to recognize the signs of leaking as soon as possible.


Signs of a waterline link include:

  • A more expensive water bill than usual
  • Unusual damp patches in the landscaping of the house
  • Foundation cracks or cracks in the pavement surrounding the house
  • Lower water pressure in the house
  • A change in temperature under the foundation where the leak may have occurred
  • Water seeping through the slab and out from the under the slab into the surrounding soil

Just because a homeowner doesn’t experience any of those signs doesn’t mean that they aren’t experiencing a leak. In addition to waterline links, homeowners can also experience sewer leaks.


Signs of a sewer leak include:

  • Persistent sewage blockages and backups
  • Cracks in the foundation
  • Infestation of rodents or insects
  • A bad odor
  • Depressions around in the lawn or the pavers around the lawn


Locate the Leak

Under slab leak detection may seem like a complicated process, but if homeowners have the right tools, they should be able to figure out how to detect water leaks under concrete with ease. Hydro-static testing can be done with the help of a professional and involves locating the sewer cleanout and testing it for a leak. Another way to find a water leak under a concrete slab is through isolation leak testing, which is a way of testing all sections of the plumbing separately until a leak is located. This is also done with the help of a professional.



Prevent Further Damage

Once you have figured out how to detect water leaks under concrete, it’s important that homeowners prevent further water damage. Homeowners should turn off the water in their homes, in order to make sure that the water cannot continue to damage the home.

Call in a Professional

Once a homeowner figures out how to find a water leak under a concrete slab, it’s important for the homeowner to call in a professional. In fact, even if a water leak hasn’t been detected, it’s still a good idea to routinely get tested for leaks. This can be especially important in the cases where the foundation has been damaged. Water damage in a foundation can compromise the structural security of the home. It’s important to address these issues as soon as possible to help preserve the home and the safety of the people that live in the house.
