The Department of Housing has said it has no proposals to amend the Pyrite Remediation Scheme, despite calls by campaigners to change the eligibility of the scheme so all buildings with pyrite can be fixed.

Pyrite, a mineral which causes cracks and swellings in buildings, is thought to be present in about 20,000 Irish homes.

A government scheme was set up in 2013 to address structural damage arising from pyrite.

To qualify for those remediation works, pyrite damage is classed under two categories.

Properties assessed as having "significant" damage, are classed as 'Category 2' and will be fixed.

However, those under 'Category 1' are not eligible for the scheme as the pyrite has yet to manifest itself as "significant".

Campaigners are calling for 'Category 1' properties to be accepted under the scheme.

They say homeowners are stuck in the middle as properties are damaged but not damaged enough to be remediated.

But the Department of Housing has said it has no proposals to amend the scheme.

It said the system is a "last resort" and is limited in its application and scope.
