Slab leakage is a severe problem the requires urgent attention and a quick fix. However, you do not have to jackhammer the entire foundation of your home to find the problem because this is the most expensive and invasivesolution available.
Slab leakage involves the leaking of water from the pipes under the surface of the concrete foundation. If left unattended for some time, it can cause severe damages to the foundation. Until a permanent solution is found,any repairs carried out on the slab will be short-lived.
Here are steps you should take when you notice slab leakage.
Step 1: Locate the Source
The first step you have to take is to find the source of the slab leakage. The success or quickness of your search depends on the type of leak itis. If it is a hot water pipe leakage, walking on the slab barefooted would help you to locate the source faster. And another rule of thumb is by looking for where water is more pooled or deepest. That is most likely the source of the slab leakage. Having located this source, take up the flooring of the the discovered source because replacing the entire floor would be expensive.
Step 2: Remove the Slab
The next step is to remove the slab where water is leaking. Given that the concrete is around 4-5 inches thick, you may need to jackhammer the spot to penetrate the slab quickly. However, do not make too big a hole but a suitable size for your hand to check for the leak. Do not make the hole any bigger until you have found the leak.
Step 3: Fix the Leak
When you have found the leak, turn off the water supply and remove the damaged piece of pipe. And, of course, you might find out that the leak is from two connected parts. Tighten up the pipe before removing it completely. If you use a copper wire, you have to weld it into the other pieces of pipe. After fixing the pipes, turn on the water supply again and check if the leakage is gone.
Step 4: Fill the Hole
Before filling or covering the hole, leave it for a few days to make sure that the leak is gone. Once you have confirmed that the leakage has stopped, fill the hole with concrete and seal it with builder’s adhesive to keep the flooring in place.
Step 5: Call a Professional
If you cannot locate the slab leakage source by yourself or you are not the DIY fan, call a professional plumber to find and fix the slab leakage in order to prevent significant damages to your foundation or compromise your basement waterproofing
