Think you have a Slab Leak?

Do you think there might be a slab leak within your house? Often signs or symptoms include observing or feeling soaked spots across the flooring. Certainly hot water spots. These can be found when walking in the home barefoot. An additional basic warning sign is usually that the water bill is substantially higher. This is caused by the fact that the pipes are leaking under pressure coming from an inward bound water pipe. As a result the water will leak all day and all night pretty much every single day. That increases your monthly water costs way up. Another warning sign that is rather frequent is that it will sound like the water is running despite the fact that all the faucets in your house are shut off.


The particular issue of slab leaks developed in the Southwestern US in the early ’80s. Back then house builders and contractors were creating homes on large concrete slabs. The home builders would pour a big concrete floor slab foundation and then lay in soft copper pipe even though the cement was still wet. The soft copper pipes would run the length and width of your concrete slab as needed to allow them to reach anywhere they wanted to get water within the house and in accordance with the layout. The water line normally would come out of the concrete floor in whichever room or space the blueprint said would need water. As an example, a water line might stick up from the foundation at every bathroom, the kitchen and near the washer hookup, to name a few.

The complication with the objective of burying soft copper piping into a cement framework was that the copper was not strong. Any kinking, folding, flexing, or nicking would weaken the water pipe and gradually develop a pin hole leak. The pipes were very often harmed during the installation or even in the cementing procedure. Building contractors were not able to go with hard copper given that it was banned within the building codes at the time.


The root cause of these kind of leaks is damaged soft copper tubing. The impaired pipes start off pin hole leaks and turn into bigger difficulties of slab leaks. What’s distinct concerning these slab leaks is that they are formed in the cement foundation. A foundation leak, by it’s own nature just isn’t a painless water leak to fix.

Repair service solutions

You will have three choices to service foundation water leaks. You are able to epoxy, jackhammer or repipe.

The jackhammer route is less very common. It’s really a hugely troublesome approach where a crew enters and removes the floor and then jackhammers into the concrete floor to find the water pipe. A piece of the water line at the leak is taken off and swapped with new pipe. This new patch of water pipe is soldered into position utilizing a plumbing professional who knows the right way to weld. Once the new patch of pipe is ready the water pressure is restored to ensure it does not leak. When it ultimately doesn’t leak, then the concrete floor is remade and the flooring is reassembled.

Epoxy lining

Epoxy liner is the process where the insides of the water lines are cleaned and then sprayed with epoxy. This seals up the hole and ceases the leaks. It has the additional benefit of possibly heading off any future leakages since the coating is applied to all of the pipes inside the slab structure. The leading problem with this method is that the coating itself becomes a drawback with time. Coming loose after frozen temperature or weight pressure may get into the water lines and can cause health fears in a case where ingested.

Copper and PEX Repiping

The most efficient option is labeled copper repiping. Repiping comes about when you simply just remake every one of the pipes in the house separate from the soft copper pipe that’s buried within the foundation. A completely new system of water lines is installed in the home within the walls and ceilings, that pretty much bypasses the existing slab pipes.


The danger of not doing anything concerning your foundation leak is that the house could be moist and moldy. You’ll be getting little water pressure and the water bills may be sky high. The risk is not making the repair in any way. The danger of the jackhammer is very major. Possible risk of the jackhammer method is not that this doesn’t work. The risk is basically you may need to get it done more than once. The truth is, in many cases any time you fix an individual leak by using this method another one appears within just a weeks time. The possible risk of the Epoxy lining technique may be the Epoxy itself can become a health risk. The ultimate approach is to do a repiping job. Not much risk is connected with copper or PEX repiping.

Cost estimations

The primarily recognized wisdom is you can anticipate to pay approximately $1,500 for every minor leak repair. Repiping delivers a permenant remedy to repairing and avoiding present and potential leaks for the life span of your household. You won’t ever have to get worried about it ever again.
