Reasons Why Slab Leaks Occur

Through our expertise and broad knowledge of plumbing issues, we have developed repair techniques that would help resolve the main causes of slab leaks, so you won’t require frequent plumbing repair.

Considering the unique nature of concrete foundations, compared to pier and beam structures, several issues may lead to plumbing leaks:

  • If the soil beneath your slab has high clay content, it may expand when absorbing water during wet seasons, pushing up the slab. This is likely to exert some pressure on and affect the plumbing within your slab.
  • During warm seasons, the high clay content soil would lose moisture and shrink. This gives less support to your slab which would experience downward movement that in turn affects the inbuilt plumbing.
  • A poorly constructed concrete slab can exert pressure on the plumbing lines.

When we undertake repair, we ensure not to pour the concrete too close to the pipes, since such close contact could easily transmit pressure to the pipes if the slab experiences even slight movement.

Why You Need Slab Leak Repair Urgently

A slab leak requires urgent attention, because:

  • The moment you notice a slab leak, it could have gone on for too long already.
  • Your entire home is built on the concentrate foundation; hence, slab leaks can destabilize your house.
  • If left for too long, repair would be even more costly.
  • The leaks can affect other fixtures and cause lots more property damage.

Once you identify a slab leak, contact us immediately for quick and effective repair.

Why Slab Leak Repair is so Sensitive

As you might already know, slab leaks are harder to repair compared to plumbing line leaks in homes built on pier and beam structures, which allow easy access to spaces beneath the floor.

Repairing a leak under your concrete slab can be invasive and costly. For this reason, you must only depend on a licensed plumber; otherwise, the issues might not be resolved or might even worsen.

slab leak repair strategies






Tunneling guarantees minimal intrusion of your concrete floor. Instead of digging directly to the slab leak, we would tunnel a path underneath your concrete slab.


This method is best used where multiple leaks exist. Instead of digging up your entire floor, we would tunnel through and repair precise locations.





Slab penetration

This is a method we would use only as a last resort, if the other less-intrusive methods cannot be applied.


Here, we’ll dig directly to the leak. Consequently, this would be a noisy procedure that would also involve replacement costs to restore the original look of your floor.


Following repair, we always make sure to restore your original floor, including tile, laminate, linoleum, wood or other types of flooring.

Concrete Slab Leaks

If your home was built on a concrete slab, this means your plumbing lines were installed under several inches of concrete. You might think that the concrete would offer added protection, but just like anything else, these lines can wear over time.

While a leak in the slab may sound scary, surprisingly, it is a fairly easy fix when done by a skilled plumbing team. The hardest part of the process is locating and accessing the leak. It is imperative that once you discover that you have a slab leak to have it repaired immediately to avoid further damage.The professionals at My Fontana Plumber can assess your plumbing problems quickly and efficiently.

What Causes a Slab Leak?

There are many possible causes of slab leaks. The problem can come from your cold supply line, hot water supply line, or your sewage lines. Here are some of the most common causes:

  • Shifting soils.In most areas of the United States moisture levels are constantly changing, which causes frequent ground movement. Shifting soils can put a great amount of pressure on your slab. Over time, this can cause your pipes to loosen or crack; resulting in a leak.
  • Improperly wrapped pipes. Water pipes should be properly wrapped and insulated during the building process. If this is not done, future problems are inevitable. Your pipes will expand and contract, especially when hot water is in use. This results in the pipes rubbing against the concrete, causing friction and wear.
  • Chemical reactions. This reaction occurs when the copper water lines come in contact with certain minerals that are found in soil. This is usually a subtle, but over time erosion can occur.
  • Damaged lines. Nicks or small punctures can occur at the time of installation, or when the heavy concrete is poured over the lines. This may be subtle enough that it goes unnoticed during the initial inspection, but can evolve into a much bigger issue as time goes on.

Signs of a Slab Leak

Sometimes it is hard for the homeowner to detect a leaky slab. If you suspect you may have a leak, look for the following signs:

  • Increase in your water bill. If you experience a significant rise in your water bill with no known cause, it is likely you have some type of leak. Many times, this will be an indication of a problem for homes with a concrete slab.
  • Wet or damp flooring. When there is a water leak the concrete will absorb the moisture, and if left long enough, it will eventually move up into your carpet, tile, or wood floors.
  • Sounds of running water.If you notice the sound of running water, but cannot locate its source, there is a good possibility you have a water leak.
  • Warm spots on the floor.If a break in the water hot water line occurs, you may experience unusual warm spots on the floor when walking around barefooted.
  • Sporadic mold or mildew growth.Mold and mildew will grow in areas where there is too much moisture. If you notice growth on carpet or flooring where there is no visible moisture, you should investigate the cause immediately. Mold can cause a plethora of problems, including serious health issues. Mold and mildew is normally accompanied by an unpleasant odor.
  • Raised area on the floor.A dome or raised area in the floor can signal a possible sewage line leak.
  • Cracked slab.Plumbing leaks cause moisture to seep into existing cracks which can cause significant structural damage. If you notice a cracked or buckling floor you should call a professional immediately.
  • Soil washed away from slab. When you notice dirt being pushed away from the perimeter of your home for no apparent reason you will want to inspect the slab. This is a sign of a sewage leak.
