Establishing the Build Up and Condition
Carrying out core sampling provides information on the material construction of the roof waterproofing, insulation incorporated and deck type whilst also providing evidence where water ingress may have occurred. Core samples are taken at strategic locations on the roof to increase the chance of establishing the exact build up, whether there is tapered insulation present, to find entrapped water in the system and to establish consistency of the build-up on the entire roof area. This usually includes multiple core samples.
Core Sample Analysis
Although water ingress usually accumulates at the low points on a flat roof, it can also be found on the other areas, for example, when an existing roof area is found to contain tapered insulation, then the falls that are visible on the surface of the waterproofing are different to the falls under the tapered boards. This can lead to water accumulation in unexpected locations. Our trained technical mangers will give guidance on this during the survey.
Photographic records of each core sample are taken and used within the finished report for visual evidence and clarification of the located.
