Visual inspection is an integral part of water seepage detection. Whether observing the severity of water seepage or inferring the source of water seepage, surveyors can have a more comprehensive understanding of the causes of water seepage cases. Especially when the water seepage source is a certain distance from the affected location, the visual method can also help the water seepage team to have a preliminary grasp of the water seepage situation.

As one of the most commonly used and basic testing methods today, moisture meter measure the conductivity value of a test object to determine its humidity. According to the current standards set by the Joint Office under the supervision of the Food and Environmental Hygiene Department and the Buildings Department, if the humidity at the water seepage location is equal to or exceeds 35%, it can be defined as having signs of water seepage at the relevant location. The case is initially considered to be established, and our team can proceed other detection methods to further identify the cause of water leakage.

The team will inject colored water into the suspected sources of water seepage (such as bathroom/ kitchen floors, bathtub or shower area. After a designated period of time, the team will observe the locations affected by the leakage to look for traces of colored dyes. Most of the colored water currently on the market has fluorescent properties. Our team will use leak detective flashlight to assist observation in dark.

One way to find the source of water seepage is to use ultraviolet identification equipment and fluorescent water agents. By using UV torch to identify whether there is a specific fluorescent reaction at the water seepage location and the type of fluorescence, the source of the water seepage can be traced.

Microwave scanning is mostly used in ceilings and walls of lower floors or properties affected by water seepage that cannot be accessed to upper floors or adjacent properties for inspection.

The principle of microwave scanning is to generate a slight electric field through a magnetron, which penetrates and penetrates deeply into the structural material being detected. Since microwaves directly measure moisture, they are extremely sensitive to water molecules, so even a very small amount of water molecules in structural materials can be detected.

Microwave scanning not only accurately detects moisture and humidity, but can also penetrate structural materials to detect moisture and humidity at different depths within the structure without any damage.

If there is water seepage, the surface of the house such as walls or ceilings will have a temperature deviation due to the water. At this time, an infrared thermal imager can be used to detect the real-time temperature of the wall. In places where the temperature is usually lower, the moisture content and the possibility of accumulation will also be higher.

After the water supply system is shut off, the team will closely monitor the flow readings of the water meters within the designated period and make relevant records. If the water meter reading shows abnormal activity during the observation period, it indicates the possibility of a water leak. If the water meter readings are the same, the source of water leakage can be eliminated.
