Water leaks are among the most frustrating and potentially damaging problems homeowners and property managers can face. Traditionally, detecting these leaks has been a challenge, often relying on guesswork and visual signs of damage, such as stains, mould, or peeling paint. Most of the time, property owners only reach out to water leakage specialists when severe leakages started occurring. However, with advances in technology, thermal imaging has emerged as a powerful tool for accurately identifying water leaks, offering a non-invasive, efficient, and precise solution. In this article, we’ll explore how thermal leak detection works, its advantages over traditional methods, and its various applications in detecting water leakage.
Traditional Water Leak Detection: The Guesswork Era
Before the rising adoption of thermal imaging, water leak detection in the waterproofing industry was largely a process of trial and error. Technicians would rely on visual telltale signs like discoloration on walls and ceilings, damp spots, or a musty smell to locate the source of the leak. These methods, while sometimes effective, were often imprecise and time-consuming. In many cases, finding the exact location of a leak required extensive and invasive methods, such as cutting into walls or ceilings, causing additional damage and inconvenience.
Engaging Thermal Scanner: A Technological Leap Forward
Thermal Scanner imaging has revolutionized the way we detect water leaks. Unlike traditional methods, which rely on visible signs of damage, thermal imaging uses infrared technology to detect changes in surface temperature. When water leaks or seepage occur, the affected area often shows a temperature difference compared to the surrounding dry areas. This is because water retains heat differently than building materials, causing the surface to appear cooler or warmer on a thermal image.
However, it’s important to clarify that thermal imaging is not like an X-ray. It does not penetrate through walls or ceilings to see inside the structure. The common obstructions in a house environment would include built-in cabinets, bulky services such as air-con compressors, etc. where the thermal imaging camera would not be able to penetrate through these services to identify if there are any seepages on the walls, ceiling or floor around these installations.
Instead, thermal scanner imaging detects surface temperature variations, which can indicate underlying issues. For example, a damp wall due to water ingress will usually appear cooler than the surrounding dry areas. By capturing these temperature differences, thermal imaging allows us to pinpoint the exact location of a leak without invasive procedures.
How Thermal Leak Scanner Imaging Works
Thermal scanner imaging cameras detect infrared radiation (heat) emitted by objects and convert it into a visible image that shows different temperatures in varying colours. Cooler areas might appear blue or purple, while warmer areas could show up as red, orange, or yellow. By analysing these thermal scanner leakage images, technicians can identify unusual temperature patterns that suggest the presence of moisture.
For example, when water leaks from a pipe concealed in the wall, it typically causes the surrounding area to become damp. This area then changes in temperature, becoming either cooler or warmer depending on the situation. The thermal scanner imager captures this difference, allowing technicians to detect the main concentrations of dampness and narrow down the leak’s location accurately.
Common Applications of Thermal Scanner Leak Imaging in Water Leak Detection
Thermal scanner imaging is particularly effective for detecting water leaks in areas like ceilings, external and internal walls, and floors. Some common applications include:
Ceiling and walls: Water infiltration through exterior walls and inter-floor ceilings can be detected by scanning the surfaces for temperature anomalies, which may indicate moisture presence. The detection is also coupled with visual inspection on the corresponding surfaces to look out for defects (e.g. cracks, etc.) to supplement the diagnosis of the potential source of seepages. At times, there may be need to cut open false ceiling boards to gain access to the underside of the reinforced concrete slab to accurately capture the damp areas.
Floor Surfaces: Leaks in concrete slabs can be challenging to detect. Thermal scanner leakage can identify areas where the temperature is unusually high or low, indicating a potential leak beneath the floor.
Mapping Hot and Cold Water Pipes: Thermal imaging can help map the layout of hot and cold water pipes within walls or floors. This is common used for bathrooms and kitchens, and is especially useful when planning renovations or repairs, as it reduces the risk of accidentally damaging pipes during construction.
The Importance of Temperature Differences
For thermal scanner service for water leakage to be effective, there must be a difference in temperature between the wet and dry areas. This is why the best time to conduct thermal imaging for leak detection is when there is a significant temperature contrast, such as after running hot water through the pipes or after rain when there are seepages into the internal surfaces.
For instance, if a leak is suspected in a hot water pipe, running hot water through the system before scanning can make the leak more apparent on the thermal image. Conversely, in cooler conditions such as after rain, moisture in walls or ceilings may show up as a cooler spot against the warmer indoor environment.
The Process of engaging Thermal Leak Detection
Initial Inspection: Upon arrival at site, the water leak detection specialist begins by performing a visual inspection of the affected area to understand the construction layout and orientation, as well as to identify any visible signs of water damage, such as stains, peeling paint, or mould growth.
Thermal Scan: A thermal camera is then used to detect the affected area(s). The camera detects infrared radiation and converts it into a thermal image, highlighting temperature variations on the surface. Areas with unusual temperature differences may indicate the presence of moisture or a hidden leak.
Analysis: The thermal images are analysed to locate the potential source of the leak. The water leak detection specialist will look for patterns or cold spots that may suggest water intrusion. Once identified, they will recommend the most effective way to repair them in order to stop water seepages. Thereafter, once repair works are carried out, owners will need to resume normal usage to further monitor and ensure no more seepages.
Conclusion
Thermal scanner service for water leakage is a powerful and non-invasive tool that has transformed water leak detection, offering greater accuracy and efficiency compared to traditional methods. By detecting temperature differences on surfaces, it allows us to identify water leaks and other issues before they cause significant damage. While it is not a substitute for a thorough inspection, it provides an essential first step in diagnosing water seepage problems. Thermal imaging is a valuable service that can save time, money, and stress.
