SOUTH Dublin homeowners whose properties are contaminated by pyrite will be eligible to claim compensation.
At least 1,000 homes nationwide are believed to be affected by the mineral that was contained in some construction materials used to build homes during the boom.
Residents in badly-hit areas of north Dublin and householder in the city council area have been able to seek compensation since last February.
Now, homeowners in South County Dublin and Dun Laoghaire-Rathdown local authority areas will be able to apply to the Pyrite Resolutions Board as well.
Around 20 homes in the area are estimated to have been hit by pyrite which can cause structural damage, with cracks appearing in the walls, the Department of the Environment has confirmed.
Foundations may also rise when pyrite is used in the construction. Last June, four houses in the Seaview Park estate in Shankhill were demolished when pyrite was discovered in the brickwork.
In total, 630 applications have been made to the board for redress so far with some 300 homes approved for inclusion in the scheme.
A budget of €20m has so far been allocated to the scheme and an Environment spokesman said any additional funding needed due to the expansion of the scheme would be made available.
By December 2014, the board had paid out €1.1m. The average cost of repairing damage caused by pyrite is put at €55,000 per home by the Department of the Environment.
Work can take up to three months to complete and people need to move out of their homes for repairs to be made.
Under the scheme, €3,000 is allocated for alternative accommodation costs and fees such as furniture removal will also be covered, though these auxiliary costs are capped.
Homeowners who have already forked out money to repair damage caused by the cheap material are not able to reclaim this cost under the rules.
In a statement yesterday from the Department of the Environment the pyrite remediation scheme was termed "a scheme of last resort".
