A suggested cap of €350,000 for compensation for homeowners affected by mica would not be acceptable as it would not fully cover 40 percent of homeowners, according to the mica redress campaign.
“We cannot leave people behind, there should be no one left behind,” said spokesman Michael Doherty.
“I’m very concerned at this kite-flying,” he said.
Various numbers for a cap were being “floated” he said, from €350,000 to €500,000.
“This is the usual form, stuff being leaked through to see where it goes. We won’t accept €350,000 as it leaves 40 percent behind.”
Taoiseach Micheál Martin has pledged a “massive programme” of public spending to pay for the rebuilding and restoration of homes affected by mica damage, but officials remain opposed to a scheme that grants 100 per cent redress for every house affected, as campaigners have sought.
A final decision on a new scheme will not be made until proposals are brought to Government, expected in two to three weeks.
Mr O’Brien met the mica steering group on Wednesday night, but differences remain within the group between representatives of the householders and department officials.
Mr O’Brien said he would publish the report of the group on Thursday, though the views of the officials and the campaigners are unlikely to be reconciled, and it is expected the report will reflect both positions.
Mr Doherty pointed out that owners already faced €40,000 in costs required for testing and planning permissions as well as rental accommodation. The figures the homeowners were basing their claims on were those used by insurance companies and were for “basic finishes” for the homes affected.
A protest will be held outside Leinster House on Thursday demanding 100 percent redress. “The fault lies with the lack of regulations and the lack of enforcement of regulations by the State at that time,” he added.
