Use a utility knife to score a line about 10 inches 25 cm long into your drywall at the location where you see visible signs of a water leak mold discolored drywall etc.
Find water leak in cement floor.
Another leakage factor comes from the water collected by gutters.
If your foundation lacks insulation is too porous or has cracks moisture can then be introduced into the slab and water will appear in the basement.
Cut into your drywall to find the source of a leak.
If the gutters are too close to a home s walls the accumulated water can lead to the deterioration of the concrete wall.
When performing a building inspection looking for water leaks be sure to take your time.
Next make sure the water is coming up from the basement floor and not falling onto it from the pipes above.
A steady stream of water may now flow down into your bucket.
If there are no other signs of a slab leak look for indications that the water heater itself is broken such as muddy water or loud cracks coming from the tank.
To find slab leaks in concrete or detect malfunctioning radiant heating systems you ll want to invest in a thermal imaging camera with a high resolution and thermal sensitivity as well as with the ability so adjust your level and span.
Tracer gas can be particularly useful when trying to find a water leak under a concrete floor or slab.
Any plugs outlets or appliances that are in water or near it can conduct electricity so turn off the power supply if needed and then grab a flashlight to do some investigating.
If your hot water heater is running most if not all of the time it may indicate that you have a hot water leak under your concrete.
With a drill and 1 2 inch twist bit drill a hole in the center of the damaged area.
Because hot water is constantly escaping your heater is working overtime to warm up the new water.
The molecular size of the gas is far smaller than the water the escaping gas will easily permeate through the concrete and emerge at the surface where it can be detected using the sniffer air sampling equipment.
Then using a drywall saw cut along the line you just scored.
When you check again if the numbers have not changed the water leak is inside your home.
Also check for any gaps in the caulk where the shower or tub meets the flooring.
Place a bucket below the damaged area of the ceiling or where dripping is occurring.
Check the water meter write down the numbers and wait another hour.
If you have a shower door splash water all around the door and frame.
If there is active dripping drill at exactly the spot where the water is dripping.
Water is detected with a thermal imager due to temperature differences caused by evaporation capacitance or conduction and these processes can be affected by weather conditions or interior humidity.
