Joe Higgins (Dublin West, Socialist Party)

As the Taoiseach is aware, pyrite is a mineral, an iron sulfide, which, when contained in the crush rock under concrete floors in new homes and exposed to moisture, oxygen and certain other minerals, expands slowly but with incredible force causing devastating structural damage, the splitting of walls and ceilings etc. I wish the Minister for the Environment, Community and Local Government would not prompt the Taoiseach until he hears the question because I have a question for the Minister as well.
