FES2 – iron sulphide may be part of the vocabulary of engineers and other built environment professionals but dramatic news headlines and heart-breaking tales of structural cracking and heave in houses have brought the word “pyrite” (FES2 – iron sulphide) to the public vocabulary. Conservative estimates of at least 20,000 houses are believed to be affected by pyrite-contaminated fill but this number could easily be trebled, and other structures may also be affected.

It is now well established where this fill came from, less so how it was allowed to be used inappropriately. But what measures are in place to ensure this situation cannot occur again and what engineered solutions have been developed to remediate pyrite affected buildings and structures?

Seminar Aim

The seminar will look at current engineering solutions and any emerging research or alternatives, dispel any myths or misunderstandings and provide a forum for stakeholders to contribute solutions to this issue. The seminar is endorsed by the Society of Chartered Surveyors and the Institute of Geologists of Ireland.
