The plight of a Donegal family whose house is literally crumbling as a result of defective blocks used during its construction could set alarm bells ring around the county.

Karl and Shirley Murtagh and their four children live in a house near Raphoe which was built with blocks containing large amounts of a substance called mica.

Over time the “weetabix blocks” begin to fall apart, leading to obvious dangers.

Now they are being forced to replace the walls of their house.

It is estimated that around 2,000 houses in Donegal could be affected.

The Mica Action Group is campaigning on behalf of those who have been affected.

See this week's Letterkenny Post/Finn Valley Post for more.

In our video clip Karl Murtagh shows one of the blocks from his house where he has been forced to have one gable wall completely rebuilt.
