Mr. Eoin McGrath:

We have research projects under way at the moment to try to identify the complete damage mechanism, because we are aware that there are multiples deleterious materials present across most rocks in Ireland, and in Donegal and in the rest of the north west. Identifying the accurate damage mechanism is key to understanding the remediation options. That research is under way at the moment both with a commercial research company and a proposed consortium of international researchers as well.
