Do you really feel there could be a slab leak in the house? Typical problems include seeing or feeling wet areas in the floor surfaces. Particularly warm water spots. These may be found when walking around the house in your bare feet. A second common symptom is usually that the water bill is appreciably higher. This can be attributable to the fact that pipes are leaking under the pressure originating from the inward water line. This means that the water leaks constantly every single day. This forces your water bill much higher. Another warning sign that is relatively common is that it sounds like water is running even when all the faucets in your house are shut off.


The circumstance of slab leaks started in the Southwest US in the early ’80s. During the time home builders and contractors were developing homes on major concrete slabs. The building contractors would pour a big concrete slab foundation after which you place in soft copper pipe even though the cement was wet. The pipes would run the full length and width in the cement slab as necessary in order to reach anywhere they required to get water around the residence and in line with the floor plan. The water line normally would rise out of the cement in whichever area the blueprint said would need water. As an example, a pipe might stick up through the foundation at each bathroom, the kitchen and near the washer hookup, among others.

The obstacle with taking that approach of burying soft copper piping into the concrete structure is that the copper was not strong. Any kinking, folding, twisting, or chipping would deteriorate the water pipe and gradually produce a pin hole leak. The pipes were commonly broken through installation and or cementing process. Tradesman were not able to implement hard copper mainly because it was not allowed within the building codes at the time.


The major cause of these kinds of leaks is negatively impacted soft copper tubing. The damaged pipes get started with pinhole leaks and grow to be even larger troubles of slab leaks. What’s unique concerning these slab leaks is they are in the cement foundation. A foundation leak, by it’s own nature isn’t a very easy water leak to resolve.

Repair choices

You’ve got 3 options to repair foundation water leaks. You can epoxy, jackhammer or repipe.

The jackhammer path is less prevalent. It is just a heavily disruptive approach where the crew comes in and takes off the floor and jackhammer through the cement to look for the water pipe. A portion of your water pipe at the leak is taken off and replaced with new water pipe. New area of pipe is soldered into position by a plumbing technician that knows the right way to weld. When the new patch of pipe is in place the water pressure is restored to verify this doesn’t leak. When it finally doesn’t leak, the bare cement is replaced and the flooring is reassembled.

Epoxy liner

Epoxy liner is a process where the insides of the water lines are cleaned and then coated with epoxy. This seals up the damaged spot and halts the leaks. It offers the additional benefit of perhaps preventing any future water leaks since the coating is put on to all of the pipes through the slab structure. The most important issue with this method is because the coating itself becomes a drawback over time. Flaking after freezing temperature conditions or weight pressure can get within the water pipes and may even cause medical fears when swallowed.


The most desirable option is labeled copper repiping. Repiping is when you basically reconstruct every one of the pipes in the house apart from the soft copper piping that’s buried inside the foundation. A fully new network of pipes is positioned in the home inside the walls and ceilings, that entirely bypasses the slab pipes.

Possible negative consequences

The chance of doing nothing concerning your foundation leak is your residential home may be wet and contain mold spores. There will be little water pressure and your water bills can be sky high. The danger is never contracting out the repair whatsoever. The risk of the jackhammer is pretty sizable. The danger of the jackhammer approach is not really that it won’t work. The risk is that you simply may have to do the work frequently. You see, usually after you fix an individual leak by using this method a fresh one appears inside of a day or two. The likely potential for the Epoxy lining method may be the Epoxy alone can become a health concern. The ultimate approach is to complete a repiping procedure. Very little risk is related to copper or PEX repiping.

Price estimations

The primarily recognized wisdom is that you could anticipate to pay about $1,500 per small leak repair. Repiping delivers a complete remedy to repairing and protecting against active and future leaks for the life span of your household. You will never need to worry about it again.
