Water leakage is a common issue in Singapore’s tropical climate, where heavy rains, high humidity, and aging infrastructure contribute to persistent seepage problems. Addressing these issues promptly is essential, as unchecked leaks can lead to property damage, mold growth, and high repair costs. One of the most effective ways to manage water leakages is by leveraging advanced detection technologies such as thermal imaging and ultrasonic leak detection to identify the sources of leaks. To ensure transparency and clarity, a detailed report consolidating the findings and proposed solutions is critical.
In this blog, we’ll explore the common types of water leakages, how detection technologies work, and why a professionally prepared report is essential for effective resolution.
Common Types of Water Leakages in Singapore
Inter-floor Leakages
Water seepage between floors is one of the most frequently encountered issues, often originating from wet areas such as toilets and balconies. Defective waterproofing membranes, wear and tear over time, or improper slope gradients can contribute to these leaks. In recent years, poorer workmanship and lower-quality materials have caused newer houses to develop leaks within a few years, compared to older properties, which typically began leaking only after more than 20 years.
Concealed Pipe Leaks
Leaking water supply or drainage pipes concealed behind walls or under floors can be difficult to detect. These leaks often manifest as unexplained water stains, constant leakages, bubbling paint, or mould patches.
Roof and External Wall Seepages
Singapore’s torrential rains can exacerbate weaknesses in roof waterproofing systems or external walls, leading to water ingress. This is more evident during the rainy season between November to January. Poor joint sealing, cracks in structures, or defective tiles are typical culprits.
Window and Façade Leaks
Improperly sealed windows or façade joints can allow rainwater to enter, especially during wind-driven rains. These leaks often appear as wet streaks or damp patches along interior walls.
Underground and Basement Leaks
Leaks in underground pipelines or basements can cause significant structural damage if not detected early. These are particularly challenging to locate due to their hidden nature. It often takes a lot of time and effort to trace and identify as water can flow anywhere.
How Technologies Help Identify Water Leakages
Thermal Imaging
Thermal imaging cameras detect temperature variations on surfaces, helping to identify damp areas or water pathways. While they do not “see through” walls, they highlight cooler zones caused by moisture evaporation.
Applications:
- Inter-floor seepages from bathrooms or balconies.
- Wall seepages corresponding to toilets and windows
- Roof leak detection where insulation may be compromised.
- Concealed hot water pipe leaks in walls or floors.
Case Study: A condominium unit experienced water stains on the ceiling below a bathroom. Using thermal imaging, we identified cooler temperature zones at the edges of the shower area, correlating with worn-out waterproofing. From the visual inspection, there was no puddling of water after wiping off which signifies that it is less likely to be concealed pipe leak.
Ultrasonic Leak Detection
Ultrasonic leak detectors pick up sound waves generated by escaping water under pressure, making them ideal for locating pipe leaks.
Applications:
- Detecting leaks in concealed water supply pipes in residential properties.
- Detecting leaks in concealed or underground water supply pipes in commercial or industrial properties.
Case Study: In an industrial building, there was a suspected concealed pipe leak in the underground fire hydrant pipe line. Ultrasonic leak detection was engaged to narrow down the potential leak areas where anomalies in sound frequencies were captured.
Preparing a Comprehensive Water Leakage Report
Once the detection process is complete, the findings are consolidated into a summary report. This document serves as a vital record for property owners, contractors, and stakeholders involved in the repair process.
What the Report Includes:
Areas of Detection:
- Clear documentation of inspected areas, including photos and supporting videos (where applicable)
- Notation of areas prone to seepage or showing signs of damage.
Findings:
- Detailed descriptions of detected anomalies.
- Infrared thermal images and ultrasonic data to illustrate the problem areas.
- Possible causes of the leak, such as waterproofing failures or pipe bursts.
Proposed Treatment Methods:
- Appropriate and recommended repair solutions
- Recommendations for preventive measures to avoid future issues.
Why Engage a Specialist for Detection and Reporting
Accurate Diagnosis
Water leakage specialists use advanced equipment and techniques to pinpoint leak sources accurately, thereby minimizing repair costs. However, some seepages may require more time and effort to trace due to their complexity. It is advisable to share as much information as possible with the water leak detection specialist, as every detail can assist in the diagnosis.
Transparency and Documentation
A detailed report ensures that all stakeholders understand the findings and proposed solutions, avoiding miscommunication during the repair process. It is also recommended to have a copy for record purposes and future reference.
Non-Invasive Approach
Water leak detection specialists utilize technologies like thermal imaging and ultrasonic detection, reducing the need for destructive methods like hacking or drilling from the get-go. Tracing water seepages may not be as straight forward at times. Instead of hacking, property owners may consider leveraging on these technologies first to take a step closer in identifying the source of seepages.
Steps to Engage a Water Leak Detection Specialist
Initial Assessment: Share your observations and photos with the water leak detection specialist to help them plan the inspection.
On-Site Detection: The specialist will use tools like thermal imaging cameras and ultrasonic leak detectors to inspect affected areas.
Report Preparation: Findings are consolidated into a detailed report with visuals and proposed repair methods.
Post-Detection Consultation: Review the report with the specialist to discuss the next steps and obtain cost estimates for repairs.
