How to Find Slab Leak and Simple 5 Options to Repair It

Any leak under a concrete floor slab should be repaired as soon as possible since it causes more than wastewater. In addition to moldy carpet and damaged hardwood floors, slab leaks can lead to expensive water damage cleanup. When water leaks are ignored for too long, the subsequent erosion can weaken the foundation and cause significant structural damage.

Symptoms and Significance

Because the slab is covered by flooring and several inches of concrete, slab leaks can be challenging to detect. An infrared thermal image can be used to swiftly find a hot water pipe if you see any warm spots on the flooring.

Slab leaks can cause low water pressure, mainly if it occurs suddenly. A plumber should be called promptly if you hear hissing or running water or see wet spots on the floor.

In the absence of any obvious signs, you may notice dampness, mold, or an increase in your water consumption. Walls, floors, and ceilings may show wear and tear over time. However, even with the most advanced electronic gear, it may take a few hours to pinpoint the exact location of the leak.

Repairing a Slab Leak: Your Options

Slab leak repair solutions are determined by where the problem is and how well your pipes are maintained. As a result, it's impossible to provide even an approximate estimate until tests and a comprehensive examination have been completed. Costs can range from a few thousand dollars to tens of thousands of dollars, depending on the repair procedure and several other variables.

A reroute or a re-piping

Rerouting plumbing above ground can avoid the need for any digging at all. A rerouting option may be quicker and less intrusive than installing new plumbing lines if a short portion of the pipe is the problem, and the problem can be dealt with by building new plumbing lines.

If a home's plumbing lines are encased in concrete and can't be accessed without ruining the slab, a complete re-piping of the house may be the best solution. Instead of running water lines underneath the slab, it is possible to do so around it instead. The plumber's primary concern is installing new pipes in walls through attic ceilings and other places where they may be hidden and protected. Crown molding, for example, can be used to cover pipes in some circumstances with a bit of creative woodworking.

While new pipes are being installed, water can still flow through the old ones, so you don't have to relocate. New lines are then connected, and the old ones are shut down.

It's time to break through the slab

Even if cutting through the Pristine Concrete slab to the problem's root may be the fastest solution, it's likely to be the most time-consuming and expensive. We only cut through the slab when no other option is available or more appealing.

When designing a slab, engineers consider the soil type, depth, and location to provide the best possible performance. While carefully re-poured fixes are safe on some slabs, no cuts should be made into them at all.

For homeowners, the consequences of breaking through the slab are severe. When work is being done on your home, you'll have no water, be subjected to a loud jackhammer and saw noise, and have to cover everything with tarps or other protective coverings.

As the work progresses, the excavated soil is either left in a large pile in your home or wheelborrowed out of the way for disposal. It is common for impacted rooms to require new flooring (certain hardwoods or tiles, for example) and additional fees for housing and meals. To fix a slab leak, one must first break through the slab, which can be very costly.

Underneath the Floor

Many homeowners prefer tunneling beneath the slab because it allows them to remain in their homes while construction is taking place, keeps their property free of dust and debris, and is generally less expensive.

Most homeowners will choose to dig over other options if their flooring is pricey. One or more rooms' worth of flooring may have to be replaced once the slab is broken from above.

Some plumbers excavate their tunnels, while others hire engineers to undertake the digging and certify the job—a plumber operating in a tunnel as long as 100 feet beneath a house must ensure structural integrity. Tunnels are excavated approximately 3' x 3' to provide appropriate working space.

It is critical that the soil that was removed be replaced correctly. Tunnels are filled up once new plumbing systems have been installed and tested. When the soil is dampened, we use metal stamps to firmly pound it back into place.

Tranquilizing and burst pipe repair are examples of trench less pipe repair

Since it doesn't require any digging or trenching, cured-in-place pipe (CIPP) has quickly become a popular choice for many households. With this easy method, water lines can be restored by applying an epoxy coating that hardens and seals the inside of the fractured piling.

This method focuses on repairing corroded pipes, gaps, or breaks in underground pipelines. The first step is to use a cutting tool to remove any debris or accumulation, followed by thorough rinsing. It is necessary to insert an inflatable tube and a resin-coated liner into the pipe. An internal pipe liner is forced against the wall by air pressure. A new plastic pipe is formed inside the damaged pipe when it dries.

Even if it sounds like a great idea, the method is not flawless. Certain contractors lack the confidence to guarantee their services. For example, this image provided by an apartment building-re-pipe firm shows a problem when the epoxy does not stick to the pipe wall or when the coating is not evenly placed. After two years, the pipe's liner shows signs of erosion due to the uneven distribution.

Repairing any following leaks will be more difficult because no heat can be applied to the area. You may be left with little alternative except to recipe, which you could have done from the start, and pay a second time to fix the same problem.

Replacement of severely damaged water pipes can be done by bursting or breaking the pipe. To avoid having to dig up the broken water line to implant a new one, an extra-large "bursting head" that fits inside the damaged pipe is used instead. It rips up the old pipe as it's pushed or pulled through.


Because of the high cost of repairs, many homeowners' insurance policies only cover a fraction of that cost. To protect themselves from slab leaks, homeowners need to be aware of the warning signs, repair alternatives, and strategies to avoid future leaks.
