Slab leaks: How it Occurs and How to Fix it?

slab leak repair

Maintaining a home’s condition is a major obligation for homeowners and they remain constantly in touch with experts for Slab Leak Repair in Fullerton. You do routine maintenance, make any repairs or updates, and manage any potential insect or mold problems. Although they are a prevalent issue, few homeowners are aware of slab leaks. The slab is traversed by several water lines, pipes, and drains, and as your house ages, you may have damage from fractures, cracks, and splits that result in a leak. Slab leaks typically manifest as substantial water damage or a rupture, however, they may not be immediately apparent.

What are slab leaks?

Water and sewer lines commonly run beneath the slab of a home, but if those lines crack or decay and start to leak, it might lead to a variety of major issues without being very noticeable. For many homes, a concrete slab foundation is a typical kind of foundation. In order to reduce expenses, the water lines and pipes are enclosed in the foundation using this foundation.

How does it occur?

When the pipes inside or beneath the foundation of a house start to leak, it is called a slab leak. Even while these leaks may first seem little and unimportant, they can cause substantial damage and expensive repairs. Unattended slab leaks can soak the ground beneath your house, causing your floors to be uneven and the structure to gradually sink into the earth.

Defective construction

Perhaps poorly fitted or low-quality pipes are the main reason for slab leaks. Because of the abrasive effects of water running over time, if your water pipes had been kinked, twisted, or dented in any manner during installation, the affected regions might lead to leaks and even burst pipes. Due to their inherent softness and susceptibility to the environment, copper pipes in particular are particularly susceptible to corrosion.

Water with poor chemistry and quality

Along with your water pressure, you should keep an eye on the pH of your water. When the water is either excessively alkaline (or “soft”) or too acidic, pipes can corrode (or “hard”). To identify acidic water, look for blue or green stains in your sink, shower, or bathtub as well as a chlorine-like stench. If this indication of a slab leak is ignored, it might result in possibly irreparable water damage, so Slab Leak Detection experts in Fullerton will help you out. Water should typically have a pH of 6.5 to 8.5.

External Pressure

A slab leak can result from pressure other than water pressure. Your home may move somewhat if the dirt beneath its foundation moves, placing pressure on the pipes. This may also occur because of:

  • a seismic event
  • a stream underneath
  • eroding soil

This kind of pressure frequently results in massive, possibly harmful slab leaks. If they are not controlled, they can result in significant floods.


Time is the main factor in both slab leaks and the bulk of the above-mentioned reasons. Older homes are especially vulnerable since they frequently have copper or galvanized steel pipes installed. For instance, corrosion is more likely to occur over time. Slab leaks can also result from pipes that have been under a lot of strain or pressure and Slab Leak Repair experts in Fullerton can assist you. Your home’s plumbing can be kept in peak condition with routine maintenance and inspections, but it’s also critical to keep an eye out for anomalies to help prevent slab leaks.


Another frequent reason for slab leaks is abrasion. In the normal course of their use, pipes may come into contact with concrete, gravel, objects, or other pipes. This persistent friction may cause the pipes to progressively deteriorate and eventually spring leaks. The danger of abrasion is larger for hot water lines. They develop leaks as a result of frequent contact with the surrounding concrete or gravel because they expand as they heat up.

Fix the slab leaks

These pipes are difficult to fix since they are not as easily accessible as other piping systems. The four most typical sorts of fixtures are jackhammering, tunneling, re-routing via the attic, and passing through old lines. Consequently, even if you cannot perform a DIY slab leak repair, you can still learn more about them.

Identify the Leak’s Location

You should be completely certain of the leak’s location before tearing up a concrete slab. To reduce the damage caused by tearing up the floor to reach the pipes beneath, you can employ a plumber for Slab Leak Detection in Fullerton to locate the leak using the specialized tools stated above.

Utilize the Proper Equipment

You’ll need to use a jackhammer to access the region beneath the cement foundation in order to fix a slab leak. This is a heavy-duty power instrument that should only be used by a skilled operator from Slab Repipe in Fullerton due to the risk of personal injury and unneeded foundation damage. You may begin the repair procedure once the under-the-slab pipes have been successfully excavated and the leak’s origin has been determined.

Get Ready for Risky Situations

A lot of dust will be created when the floor is torn up. The best course of action is to remove any furniture, artwork, carpets, electronics, and priceless items from the room. Then, ensure you wear safety equipment like steel-toe boots, heavy-duty clothing, gloves, goggles, and a breathing mask. Having a helper is preferred, but they must be provided with the appropriate safety gear.

Consider Your Repair Options for Slab Leaks

Depending on where the issue is and the overall state of the pipes, there are several slab leak repairs that Slab Leak Repair experts in Fullerton will do. Here are a few typical choices:

  • For a single leak with reasonably simple access, spot repair is suitable. A short part of a leaky water pipe or sewer line is repaired by cutting through the concrete. Although this is a typical option for industrial plumbing, the considerable rehabilitation required for houses makes it potentially expensive and intrusive.
  • Insurance companies frequently demand re-piping or re-routing in order to maintain coverage. Old plumbing is removed during this operation, and new pipes are rerouted via the attic or along the slab’s exterior edge.
  • Pipelining includes applying a thin layer of non-toxic epoxy coating to the internal surface of the pipes. It’s a cheap solution for fixing little leaks in primary sewage lines or pinholes in copper pipes. It is ineffective for more severe injury, though.

Contact EZ Leak Detection for Slab Leak Detection in Fullerton as soon as you can so they can locate the leak and counsel you on the best course of action. If the leak can be quickly patched with epoxy, your property might only need to be re-piped. A specialist can assess the situation and provide a solution in any case. By acting quickly, you might prevent significant damage to your home and long-term costs for your family.
