Under the scheme, devised by Minister for the Environment Phil Hogan and officials from his department, banks will provide up to €50m in loans to a special fund which will be established to assist pyrite homeowners.
Once those homes are repaired, the scheme will then turn to homes where pyrite is present but which have not yet suffered damage.
Details of the timeframe for the scheme and the level of levies to be applied to certain stone and insurance products have still to be worked out in discussions between the Departments of the Environment and Finance.
However, it is understood that the stone levy may be in the region of 80 cent per tonne, while the insurance levy is likely to be around 0.5% of the value of non-health insurance policies.
The fund will be administered jointly by stakeholders in the scheme, including the Construction Industry Federation, the Concrete Federation and structural insurer, Homebond.
These include 850 in need of immediate repair, 1,000 that have already been repaired and a further 10,250 houses where pyrite has been found, but structural problems have not yet arisen.
As part of the plan, approved by Cabinet, a Resolution Board will also be set up to determine which home owners are entitled to money from the fund.
It is expected that the average amount of funding that will be made available to the owners of pyrite damaged homes will be in the region of €45,000.
