Clare County Council admits pyrite problems in up to 620 homes

This pyrite-invested block literally disintegrates in the hand in a garden in Ballina, Co Mayo.

Clare County Council has admitted that up to 620 homes in the county may be impacted by pyrite, meaning it could be the worst affected county in the country.

Neighbouring county Limerick has been included in a tender from the Department of Housing for pyrite remediation works, sparking fears that the problem could be far more widespread in Munster than previously thought.
