A €20 million repair scheme has been approved by the Government for homes affected by pyrite and mica.
Under the scheme homeowners will pay for 10% of the repairs, with the State covering the balance.
Up to 5,700 homes in Donegal and north Mayo have been affected by problems in their concrete blockwork causing buildings to disintegrate and external plastering and rendering to crack.
The Cabinet backed the establishment of a repair scheme last October.
Ministers Joe McHugh and Michael Ring, from counties Donegal and Mayo respectively, met with Taoiseach Leo Varadkar regarding the scheme today.
In 2017 an expert panel review concluded that concrete blocks sold in Donegal and used in housing there over a period of years were not fit for purpose.
But the expert panel was not set up to lay blame or to show how homeowners could be compensated, so affected homeowners have campaigned since for redress.
