The identification of ‘basic’ or common minerals is carried out in-house. More complex chemical analyses (such as establishing whether a preservative is present in a timber sample for example) might involve sending samples on to the appropriate UK accredited laboratory for spectographic analysis and/or SEM identification.
Investigations of damp proofing systems and associated building materials of both heritage assets and newer construction are carried out.
Gravimetric analysis of masonry/mortar samples is sometimes carried out as part of a damp survey.
Identification of timber species is carried out in house using microscopic examination of thin sections when necessary.
This is used for strength grading (where the structural capacity of softwood is defined by – amongst other things – its species).
