I want to be clear. I am not going to name the quarry, but it has repeatedly been publicly identified. There is one quarry in Donegal that is primarily associated with the vast majority of defective blocks. We are talking about thousands of public and private homes in Donegal. Has the quarry been extensively examined from a geological point of view to try to understand what has led to this absolute scandal and to prevent anything like that happening again?
