|Building Conservation: Non - Destructive Investigations|
Non – Destructive Investigations
Just like physicians and surgeons who use stethoscopes and keyhole surgery to examine the internal organs and check their patients, EBS building pathologists employs a range of non-destructive instrumentation to check their buildings. This will save unnecessary exposure work and the destruction of the historic fabric. Non-destructive inspection techniques enable the condition of timbers tobe ascertained without opening much of the building fabric; they are therefore especially valuable in buildings of historic and architectural interest. For example using advanced detection techniques with the Resistograph, to determine the exact location and type of decay and this approach is completely non-destructive.
EBS carries out a visual inspection of buildings for mould, damp and timber decay in the problem areas and this is backed up with non-destructive instrumentation and technologies to determine the type, extent, cause(s) of damp and timber decay. A technical report is prepared for conservation repairs, chemical free solutions to woodworm and death watch beetle and fungal infestation. EBS employs a range of moisture meters, Endoscopes, Borescopes or Fibre Optic Inspection. Interpreting information from fibre optic inspection requires practice on site. It can be easy, for example, to confuse spiders' webs with fungal mycelium. Borescopes are excellent at allowing an assessment of the distance that a dry rot outbreak has grown from its origin. They can avoid damage to precious wall coverings and avoid the necessity for wide scale lifting of timber to allow access to hidden areas. EBS also carries out Timber Stress Grading and Species Identification for engineers.
