Sub-Surface Water Leaks
Water suppliers across England and Wales have seen great increases in the amount of water leakage across their networks. In 2013, an average of 3,113 megalitres of water per day was estimated to have been lost (that’s over 1 TRILLION litres per year).
We successfully undertake projects with water suppliers to undertake subsurface water leak surveys using our UAV mounted thermal imaging camera. On cold mornings (0C-2C) any escaped water (10C-12C) is clear on the thermal image. The benefits of using a UAV mounted thermal imaging camera is that it allows survey of large areas in a short space of time and with access typically difficult or inaccessible areas such as rural land.
The same UAV mounted thermal imaging technology can also be used to detect subsurface steam leaks from district heating networks. The strict environmental conditions are not as necessary, as the steam running through the pipe is a lot warmer and much more visible on the thermal camera.
Thermal Building Inspection
Infrared Thermography is also used to evaluate the condition of building envelopes. We can accurately detect:
- • Moisture entrapment
- • Delamination of roofing elements
- • Water ingress points
- • Concealed defects
- • Air loss
The swift detection and pinpointing of such defect can help those in charge of looking after the condition of ageing or new buildings to better plan and manage remediation works with much greater certainty. Often, the repair works that are discovered are in hard to reach area.
UAV thermal imaging technology can be used to enhance BREEAM grade advanced building inspections. Typically, thermal building inspectors have trouble obtaining quality thermographic information about the roof and upper levels of facades on building envelopes due to access on and around a site.
Thermal imaging of commercial and domestic buildings can help identify inadequate, damaged or missing insulation, and air leaks and moisture intrusion.
