Project Info

Our client, a large online retailer, had recently purchased a distribution centre in North England. The initial building survey had indicated the roof to be in a satisfactory condition however within 3 months of handover several regions of ingress were noted. This caused disruption to the distribution network and solutions had to be identified quickly.  

 

How IRT Surveys helped: 

Services used :

  • Thermal Imaging
  • Drones
  • Electronic Leak Detection

Outcome

The 48,000m2 roof was surveyed in 6 hours using high resolution thermal and visual imaging. IRT then used the thermal data to  pinpoint regions of trapped moisture and damage below the waterproofing. This allowed targeted electronic leak detection testing to be carried out in only the sections requiring attention. In total, 892 penetrations were detected and marked directly on the roof surface. These penetrations contributed to 1291 m2 of damaged insulation. Our high resolution drone imaging allowed us to create an 80 mega pixel visual image of the entire roof allowing the client to zoom in and read identified penetrations markings just 4 inches in size.
