A revised mica redress scheme will be brought before Cabinet later.
The scheme will cover 100% of the costs of rebuilding work up to a cap of €420,000.
There will be a cap on the amount per square foot to ensure costs are not a blank cheque.
The scheme will also include a €10,000 rental accommodation allowance.
Housing Minister Darragh O'Brien intends to appoint a Senior Counsel to review how the issues happened in the first place.
While a new building standards regulator will be set up to prevent such issues occurring again
While families representing households affected by mica will meet officials in Europe as part of their campaign for 100% redress.
The delegation will hold talks with the European Committee on Petitions in Brussels along with MEPs.
Eileen Doherty is a mica-affected homeowner and campaigner.
"We will highlight the fight of mica and pyrite-affected families in Ireland.
"Effectively the Irish Government has not adhered to EU directives on the bringing in of concrete products into the Irish State.
"And as a consequence, the issue has arisen of the mica families in Donegal and the pyrite in Mayo".
Speaking on Newstalk last week, Minister O'Brien said the revisions would mean the scheme was 'significantly better' than what's there.
"I inherited this scheme - and I promised and I made a commitment that we want to make it better, we want to make it workable.
"Loads of good work has gone into it - will residents know before Christmas? Absolutely.
"What I can say to you is the revisions to the scheme that I'll bring forward will be significantly, significantly better than what's there."
