A motion calling for 100% redress for homeowners affected by mica has been adopted by the Dáil.
The motion, which was put down by Sinn Fein, was not opposed by the Government.
It is seen as another huge step for homeowners left devastated after their homes were built with defective blocks.
The motion also follows a momentous day in Dublin when thousands of Donegal people marched to Dail Eireann demanding 100% redress.
Two amendments were adopted, including one from Aontú leader Peadar Tóibín calling for a public inquiry into the scandal.
Earlier, Mr Martin told the Dáil that the final bill would exceed €1 billion.
The Taoiseach said “everyone wants to do the right thing”, however he added, that the issue of redress is complicated by the fact that different homeowners have different issues.
He said Housing Minister Darragh O’Brien was now going to have a fresh look at the existing scheme to see how it could be improved.
Taoiseach Micheál Martin has said the Government will “do everything we can” to assist homeowners affected by mica – saying what happened was scandalous, appalling and devastating.
The Government is “anxious” to get any new scheme up and running as soon as possible, Mr Martin added.
Sinn Féin leader Mary Lou McDonald said that mica had devastated both the homes and lives of those it affected.
She said homeowners had been failed by the system and failed by the State and now lived in homes that “are literally crumbling around them”.
She said the homeowners were “determined to get justice” and Sinn Féin had promised to “do everything we possibly could for a 100% redress scheme”.
The Taoiseach told Thomas Pringle that the Government would deal with the upfront cost of having a defective home assessed and with the “rental issue”.
Deputy Pringle asked if the people of Donegal, which he described as the forgotten county, can expect a response by the middle of July.
Responding, the Taoiseach said that was the intention because “this thing has gone on too long”.
