How to Detect Leaks Under Concrete Slabs

Water leaks at home are not only disruptive to your plumbing, but they can also rack up higher expenses. Be it for repair costs, water bill inflation, or worse, damage to your property, any leak can seriously hurt your pocket.

But among all leaks, under-slab leaks are one type you should pay extra attention to. Besides not being easily noticeable, this hidden leak can cause serious damage to your walls and foundation. If you’re not prompt in detecting them, hefty plumbing repair and home renovation costs might just surprise you one day.

Good thing Peach Plumbing & Drain gives you some tips on how to detect under-slab leaks in this made-easy plumbing guide.

Visual Inspection

Narrow your leak detection by first focusing on the visible signs of a leak. Look for signs like damp patches, water pooling, or cracks in the floor. Sometimes, you may also notice unusual sounds, like the sound of running water when no taps are on. If you spot any of these red flags, there’s a chance that a leak might be hidden underneath the slab.

Dye Test

One easy DIY method to detect water line leaks under a slab is a dye test. This works best for leaks in your water pipes. Simply add a non-toxic dye to your water supply and keep an eye out for any colored water that appears on the surface of your concrete floor. If the dye shows up, you’ve identified the spot where the leak is occurring. It’s a quick and effective way to narrow down the problem area.

Moisture Meter

For a more thorough approach, a moisture meter can help detect high moisture levels in your concrete slab. These handheld devices are easy to use and give you a reading of the moisture content in different parts of the slab. If the meter detects moisture where it shouldn’t be, it’s a clear indication of a leak underneath that area. This method is particularly useful when water line leaks aren’t visually apparent, but you suspect water buildup below the surface.

Thermal Imaging

If you’re dealing with a hidden leak or want to take your inspection to the next level, a thermal imaging camera is a powerful tool. This device detects temperature differences in the concrete slab, allowing you to identify areas where water has seeped in. Leaked water will typically create cooler spots in the concrete, which a thermal camera can easily pick up. It’s a non-invasive, efficient method that’s great for locating leaks without tearing up your floor.

Water Pressure Test

If you think the leak is related to the plumbing under the slab, a water pressure test is your go-to solution. Turn all water sources in your home shut and observe your water meter. If the meter shows water usage, there may be a hidden leak in the pipes under the slab. You can also test specific plumbing sections. Isolate them and check for pressure drops in different areas. This test helps confirm whether the plumbing is the cause of the leak.
