To begin, the individual needs to choose a small area of the concrete slab to test.

Using a rubber mallet or a similar tool, they should gently tap the surface.

If the sound produced is dull, it often indicates solid concrete. A hollow sound, however, may suggest a void beneath the surface.

This void could result from water erosion or other issues related to leaks.

Listening carefully is crucial. A pronounced hollow sound may mean there is less material below, allowing water to accumulate.

It’s important to note that while this method can signal a problem, it is not definitive proof of a leak.

Other inspection methods may still be necessary for a thorough assessment.

Performing this test in various spots can provide more information about the slab’s condition.

If a pattern of hollow sounds appears, further investigation is recommended.

Determining the presence of a water leak under concrete can prevent more serious damage down the line.

Regular checks can help maintain the integrity of the concrete structure.

6) Use an infrared camera to detect moisture

An infrared camera is a powerful tool for detecting moisture beneath concrete.

This device can find temperature differences that indicate the presence of water. When water leaks occur, the affected areas often retain heat differently than dry surfaces.

To use an infrared camera effectively, it is best to conduct the inspection on a dry day.

Rain or high humidity can lead to false readings.

The camera should be pointed at the concrete to capture thermal images, showing any irregular patterns.

The technician can identify cool spots that may suggest hidden water.

This process is non-invasive and allows for quick location of issues without damaging the concrete.

Infrared cameras are especially useful in identifying leaks in difficult-to-reach areas.

For example, they can detect moisture in walls and floors, providing a clearer picture of potential problems.

This method relies on thermography, which visually represents temperature variations.

The colour-coded images help pinpoint leaks and inform necessary repairs.

Many professionals prefer using infrared imaging as it saves time and reduces guesswork.

This technology aids in making informed decisions about maintenance or urgent repairs.

It is a practical and efficient way to ensure the integrity of a structure.

7) Watch for low water pressure

Low water pressure can indicate a water leak under concrete. This issue may stem from damaged pipes that are losing water.
