Question Number(s): 557 Question Reference(s): 17328/19
Department: Housing, Planning and Local Government
Asked by: Thomas Pringle T.D.


To ask the Minister for Housing; Planning and Local Government the status of the provision of financial supports for persons affected by MICA in County Donegal; and if he will make a statement on the matter.


The Expert Panel on Concrete Blocks was established by my Department in 2016, to investigate problems that have emerged in the concrete blockwork of certain dwellings in Counties Donegal and Mayo.

In 2017, the report of the Expert Panel was published and included eight recommendations, which my Department is actively progressing with the relevant stakeholders, prioritising the implementation of Recommendations 1 and 2.

With regard to Recommendation 1, the National Standards Authority of Ireland (NSAI) established a Technical Committee to scope and fast track the development of a standardised protocol. The standardised protocol will inform the course of action in relation to remedial works for all affected householders.  The standardised protocol was published by the NSAI on 13 November 2018 and ‘I.S. 465:2018 – Assessment, testing and categorisation of damaged buildings incorporating concrete blocks containing certain deleterious materials’, is available at

The standard can be used to assess and categorise the damage in properties where the concrete blocks are suspected to contain the minerals mica or pyrite. Previously, there was no common way for engineers or homeowners to assess the damage caused by defective concrete blocks, in order to decide what, if any, remedial work could be carried out.  The standard:

  1. establishes a protocol for assessing and determining whether a building has been damaged by concrete blocks containing certain excessive amounts of  deleterious materials (free or unbound muscovite mica, or aggregate with potentially deleterious quantities of pyrite);
  2. describes methods for establishing the extent of the problem;
  3. describes the scope of any testing required; and
  4. categorises buildings, in  accordance with the standard, providing competent persons with guidance on the appropriate measures to be taken.

With regard to Recommendation 2, my Department has been in contact with Engineers Ireland in relation to the establishment of a register of competent engineers for homeowners/affected parties’ reference. Engineers Ireland has provided assurance that they are in the process of finalising measures to establish such a register now that the standardised protocol is in place. Engineers Ireland have issued a call for suitably qualified engineers to participate on the register.  They have recently announced that training will be provided in May for those engineers with the aim of ensuring consistency throughout the industry in assessing and categorising the damage.

In 2017, I visited Donegal and Mayo and met with key stakeholders, including affected homeowners, elected members and officials of the local authorities and other interested parties. I made similar visits to both counties last year and I will continue to monitor the situation and to update affected parties on progress.

Under Budget 2019, the Government approved in principle the development of a grant scheme of financial assistance to support affected homeowners in the two counties to carry out the necessary remediation works to dwellings that have been damaged due to defective concrete blocks.  Work on the development of such a scheme is well underway, including discussions with the Department of Public Expenditure and Reform in relation to the operation and funding of the scheme.  It is intended to revert to Government with proposals for the scheme shortly, with a view to publishing details of the scheme thereafter.
