Questions about water damage on concrete slabs, including how it happens and how to look for it, are answered here. Read on to find out what happens next!

What is a Slab Leak?

Whether you’re a first-time buyer or a seasoned homeowner, you might be surprised to learn that water damage can add up to thousands of dollars before you notice a leak.

In the case of slab leaks, this is literal.

This is a direct description of slab leaks.

Exactly what are the most common reasons for slab leaks?

  • Chloramines that eat at the interior of piping systems. Chloramines, a class of disinfectants used to remove bacteria from water, are particularly damaging to copper plumbing because of their chlorine and ammonia content.
  • Electrolysis, which occurs when two dissimilar metals come into contact, is another cause of premature pipe corrosion.
  • When water flows through them, pipes expand and wear down against other surfaces, a common cause of pipe failure is abrasion.

There is not much that can be done. However, what you can do is educate yourself before the worst happens.

Slab Leak Detection

Before it reaches your walls or floors, a water leak underground can do a lot of damage. Slab leak symptoms frequently resemble those of other types of leaks, such as pinholes.

For this reason, prior to making any expensive repairs or attempting any do-it-yourself solutions, it is strongly recommended that you consult a leak detection expert.

Experts in leak detection can typically determine the source and type of a leak for between $150 and $400, depending on the complexity of the job.

When a slab leak is suspected, there are a few telltale signs to look out for. These include:

  • Unusually high water bills: One of the first signs of a slab leak will be your water bill. If there is an unexplained spike in your bill but no difference in your actual water usage, call in an expert as soon as possible to evaluate your plumbing system.
  • An abnormally high water bill is one of the earliest warning signs of a slab leak. If your water bill suddenly skyrockets without any change in your usage, you should have a professional plumber take a look at your pipes right away.
  • Surprisingly high water bills: a slab leak might be detected early on by a rise in your water bill. If your water bill suddenly skyrockets without a corresponding increase in consumption, you should have a professional plumber look it over as soon as possible.
  • If you have a slab leak, one of the first things you’ll notice is a spike in your water bill. Call a plumber right away if you notice a sudden increase in your water bill without a corresponding increase in consumption.
  • Water bills that seem to rise out of nowhere are one of the first warning signs of a slab leak. If you notice a sudden increase in your water bill but haven’t increased your usage, you should have a professional plumber take a look at your pipes right away.

How Do Concrete Slabs Get Water Damaged?

Surprisingly high water bills: a slab leak might be detected early on by a rise in your water bill. If your water bill suddenly skyrockets without a corresponding increase in consumption, you should have a professional plumber look it over as soon as possible.

Having water seep into your concrete slab can cause it to crack. Then, cracks can result in more moisture seeping through your concrete.

As water keeps creeping into your slabs, it may be absorbed by the soil beneath your concrete. The stability of your building could be compromised if this happens to the foundation.

To prevent water damage to your concrete, it is important to be aware of the potential sources of such damage. In excess groundwater, a rising water table, and a burst pipe beneath the foundation are the most common sources of water damage.

If this doesn’t happen, you’ll have to deal with mold development, soaked building materials, and your flooring losing its grip.

How to check your concrete slab for water damage

It’s not always easy to spot the signs of water damage, especially if it’s happening below the surface. For this reason, you should hire a service to conduct hydrostatic testing on your concrete.

Hydrostatic testing can help detect plumbing leaks. However, only trained experts should attempt this. You can, however, watch out for signs of water damage in your home.

Plumbing leaks can be found with the help of hydrostatic testing. But this is work that can only be done by experts. However, you can take steps to protect your home by being alert for signs of water damage.

Mold development is another potential problem. Mold and mildew can form on exposed concrete that has been saturated with water.

Mold and mildew can degrade carpeting to the point that it collapses. Termites and ants might attack your property if it has water damage. It’s safer to play it safe and get in touch with an expert if you see anything like this.

Steps In Repairing Water Damaged Concrete Slab

Step #1. Assess the water damage

The first stage in restoring a water-damaged building is, predictably, an inspection of the damage. Doing so will help you determine if you can handle the issue on your own or if you should call in an expert.

Moreover, it is important to keep track of the destruction. This will assist you and your attorney make a stronger case for your insurance claim. You should also call your insurance provider right now and inquire about policy details.

Step #2. Clean the surface

If there is any water or debris on the surface, please remove it. Soap and water might not remove water stains, therefore concrete cleaners are your best bet.

In order to remove stains from concrete, you can choose from a variety of cleaners designed for specific stains. Instantly eliminate mold and mildew stains with RMR-86 Stain Remover Spray. It’s a specialized cleaner for concrete that can remove the stains you specified.

Step #3. Determine areas of repair

Once the area has been cleaned and inspected for damage, you will have a good notion of what areas of the concrete need fixing. Pay particular attention to the places where water has pooled because this is where the most damage will occur, including extensive cracks and buckling. After figuring out what needs fixing, clean the area completely.

Step #4. Minor damage

A thin layer of concrete can be applied to the surface to repair minor surface damage. Use concrete patching material to repair any minor cracks or holes. However, we still advise you to have a professional investigate the water damage to your concrete slab, even if you don’t observe any further problems.

Tips on how to protect your concrete slab

Concrete may be simple to fix if the damage is modest. Nonetheless, they cause expenses and physical harm to your house. Keeping this in mind, we came up with some basic precautions you may take to safeguard your concrete floor.


Porosity in concrete was already mentioned. Therefore, a protective sealer is required to make it stain-proof and water-resistant.


Stains that occur on your concrete surface must be removed immediately. We don’t want to risk the concrete getting damaged if we leave them there for too long.

How Much Does Slab Leak Repair Cost?

It can get expensive to fix a slab leak.

HomeAdvisor reports that the typical cost to fix a slab leak is around $2,280.

While this is happening, the average cost to fix a pipe is around $630. However, if complete repiping and damage remediation are needed, including mold or asbestos abatement, the cost of repairs might rise to $10,000 or more.

A slab leak job might take anywhere from one to three days to finish, depending on the age of the pipes and the level of damage.

A plumber will need to cut into the foundation, inspect the damage, fix the leak, and then patch the foundation back up. Additional fees could be incurred for the installation of new pipes, cleanup, and the repair of any hidden water damage.

A slab leak is a major repair that should be made to your property, so it may be covered by your homeowner’s insurance.

Deconstruction and foundation repairs should be included in the tear-out clause. The simplest pipe replacement jobs may also be covered by insurance.

Additional expenses, such as labor, non-water-related damages, and infrastructure repairs (re-flooring, painting, patching, etc.), may not be covered.

Get in touch with your insurer to inquire about rates and whether or not damage caused by water, whether sudden or prolonged, is covered.

What Factors into the Cost of a Slab Leak Repair?

You can never be too prepared as a prudent home or company owner. It is possible to save both time and money on plumbing repairs if you know and understand what the issue is.

Costs will be affected by factors like the type of damaged water line and its location. Another factor to consider when balancing your budget is the scope of the job involved.

We have compiled a list of the variables that will contribute to the final price of slab leak repair. Those things are:

  • When fixing a leak under the slab, the plumber has to break up the concrete to get to the pipe. Costs might range from $500 to $4,000, depending on the leak’s location and the extent of the damage.
  • When a customer refuses to demolish a section of their foundation or flooring, a reroute is often the solution to a slab leak. In the range of $300 to $1,500, the average cost to reroute a system of pipes is between 300 and $1,500.
  • Fixing a broken waterline or water main might cost as little as $500 and as much as $3,000. The amount of the damage will determine the final cost.
  • Repairing a broken pipe might cost anywhere from $400 to $850 on average.
  • Repairing or replacing the foundation may be necessary if the damage is extensive. This is a massive undertaking. Additional factors such as the thickness of the slab, cost of materials, and square footage will also influence the price range. Total slab repair or replacement can cost anywhere between $3,600 to $7,200.

A plumber’s rate can also be affected by a number of other variables, including:

  • Demolition and excavation work are two different processes. The subsurface pipes need to be accessed and repaired, which necessitates excavating the soil.
  • The foundation, flooring, basement, and other home infrastructures are all at risk if there is water damage, but this is not an exhaustive list.
  • If you need a new slab foundation poured: If there has been extensive damage, or if you require total repiping, a new concrete slab may be needed. This will add extra time to the project, as the concrete mixture needs several days to fully set.

4 Tips for Concrete Maintenance

Annual Cleaning

Don’t assume that cleaning your outdoor cement surfaces with rain water is sufficient. Grease and filth might accumulate on your slabs, and rain water might not be strong enough to clean it. If you give it a good cleaning once a year using a light detergent, power washer, and push broom, you can keep stains and discolouration at bay. This is the cornerstone of proper care for your concrete floors.

Apply Sealant

After a thorough cleaning and drying, a quality sealant should be applied to the surface of your slab to give crucial UV protection and a protective barrier against surface damage. Sealant’s water-repellent properties can be a huge help in protecting against the weather. Sealants are readily available and can be found in close proximity to the concrete repair materials at most hardware and home improvement stores.

Expansion Joint Maintenance

When you are cleaning and checking your patios, driveways, and other surfaces, don’t forget to look at the expansion joints, as well. Having water penetrate under your cement slab and contribute to settling is a sure sign that the expansion joints have been compromised. We’d be pleased to talk you through our expansion joint repair procedure if you’ve detected cracking in the filler. Inquire Now!

Routine Monitoring

Inspecting and keeping an eye on your concrete surfaces on a regular basis is another crucial part of slab maintenance, as it allows you to spot and fix small fractures before they spread and cause settling and other problems. If you have cracks or separations in your concrete that you believe are too large to be repaired using retail concrete repair materials, don’t hesitate to get in touch with our concrete leveling specialists.

Preserving and restoring the condition of your concrete floors can require a lot of work. Unfortunately, no amount of effort will be enough to keep cement slabs from cracking and sinking.
