Property Risk Check

Mica & Pyrite in Ireland

Check defective concrete block (mica and pyrite) risk and grant-scheme designations for any property across all 26 Irish counties. Powered by official government data sources.

Risk Overview

How do I check a house for mica or pyrite before buying?

Mica and pyrite are defective concrete block problems that cause progressive cracking and, in serious cases, structural failure. Start with where the home is and when it was built: certain local-authority areas are designated under the State’s Enhanced Defective Concrete Blocks grant scheme, others fall within the older Pyrite Remediation Scheme, and most affected homes date from the late 1990s onward. A PropertyPack report flags whether a property’s area is covered by either scheme as one of its official checks.

Area cover is the screening step, not the diagnosis. Where there is real doubt, a competent person carries out an assessment to I.S. 465, the national standard, which core-samples the blocks and grades the damage. Ask the seller whether such an assessment exists before you bid, and treat visible external render cracking as a prompt to investigate, not proof on its own.

How this banding works: higher counties are whole local-authority areas designated under the Enhanced Defective Concrete Blocks grant scheme; medium counties are designated in part or fall within the Pyrite Remediation Scheme area; the rest are not currently designated under either scheme. Designation describes State grant eligibility for an area, not a verdict on any individual home, and defective blocks can still affect a house outside a designated area.

Mica & Pyrite FAQ

Frequently asked questions.

Which counties are designated for the mica and pyrite schemes?

The Enhanced Defective Concrete Blocks Grant Scheme designates Carlow, Clare, Donegal, Limerick, Mayo and Sligo in full, with Dublin, Meath and Wexford designated in part (certain local-authority areas only). Separately, the Pyrite Remediation Scheme covers pyritic heave in parts of Dublin, Kildare, Limerick, Meath, Offaly and Westmeath. Designations have expanded over time, so check the current position for the specific area.

How do I check if a property in Ireland has mica or pyrite?

Start with the property's Eircode on PropertyPack.ie: the report flags whether its area is covered by the Defective Concrete Blocks grant scheme or the Pyrite Remediation Scheme, alongside the build era. For a confirmed diagnosis, a competent person carries out an assessment to I.S. 465 (revised edition published June 2026), which core-samples the blocks and lab-tests them.

What is the Defective Concrete Blocks grant scheme?

The Enhanced Defective Concrete Blocks Grant Scheme helps owners of homes damaged by defective concrete blocks (mica or pyrrhotite) to remediate them, with grants up to €462,000 per dwelling in designated local-authority areas. To June 2026 the scheme had 3,598 applications and 542 completed remediations.

Should I still buy a house that might have mica or pyrite?

It is not an automatic no, but factor in the risk before you bid. Ask for any I.S. 465 (revised edition published June 2026) assessment, check the build era (many affected homes date from the late 1990s onward), and confirm whether the area is covered by a State scheme. The Pyrite Remediation Scheme closes to new applications on 30 November 2026, so timing matters for pyrite-affected homes.
