Forensic Assessment of Sulphide Damage

Pyrite, Mica and Pyrrhotite are naturally occurring minerals found in sedimentary rocks, and the aggregates used as construction materials in Ireland. When these minerals react with moisture and oxygen, they produce sulphates that can cause swelling, cracking and gradual deterioration of the concrete and masonry used in the floors and walls. This type of damage is easily mis-diagnosed as subsidence, but we’ve assessed over 500 buildings damaged by these minerals so we know the difference.
