Expert Aerial and Terrestrial Infrared Surveys

Nationwide Drones provide surveyors and engineers with expert aerial and terrestrial infrared surveys to give a better insight into the true condition of buildings and structures beyond what can be identified visually and without intrusive testing.

Crucially, we have developed our drones to fly with fully radiometric infrared sensors, meaning we’re able to post process the images to identify what anomalies there are. Whilst off the shelf solutions are great tools for search and rescue, identifying a ‘hot’ body in a ‘cold’ field, they’re unable to deliver the detail our clients require.

Infrared can be used to identify:

  • Heat loss from properties
  • Areas of missing/damaged insulation
  • Trapped moisture within flat roofing systems
  • Poor detailing
  • Delaminating render and spalling concrete
  • Porous brickwork
  • Hidden detailing/changes in fabric
  • Waring and build up of debris to lining of pipes/tanks/furnaces

Conditions for using infrared thermography on buildings and structures:

  • Survey and analysis carried out by qualified (ITC/PCN) thermographer
  • Using a fully radiometric infrared and high resolution (640×520) sensor
  • Survey carried out after sunset – long enough for there to be no solar gain
  • 10degC temp differential when looking at buildings
  • Dry – water on the surface will hide defects behind

Where can you benefit from an infrared inspection:

  • Condition surveys
  • Acquisition/disposal surveys
  • Latent defect/warranty surveys
  • BREEAM assessments
  • Energy efficiency audits and MEES assessments
  • PPM including Mechanical and Electrical and hidden services
  • Overhead power line, wind turbine and PV solar panel inspections

Benefits of combining aerial infrared with terrestrial:

  • No need to gain access onto roofs at night
  • No personnel having to work at height
  • Better quality data of high level elevations and roofs – closer and at a perpendicular angle.
  • 8 frames per second means we gather surplus data to ensure no defect is missed.

Can't visually identify the extent and cause of a defect?
