Purpose of the Grant Scheme
The Defective Concrete Blocks Grant Scheme is available to financially assist homeowner(s) to remediate their dwelling, where it has been damaged using defective concrete blocks in its construction.
The grant scheme is a scheme of last resort for affected homeowners who have no other practical options to remediate their dwellings.
The grant scheme will be operated and administered by Mayo County Council.
Who does the grant scheme apply to?
This grant scheme applies to the owners of dwellings, located in County Mayo, which are damaged due to defective concrete blocks containing excessive amounts of deleterious materials, namely mica or pyrite.
Under this grant scheme an owner can only apply for one dwelling and a dwelling can only be the subject of one grant (one owner, one dwelling – one dwelling, one grant).
The dwelling must be the individual’s principal private residence.
How do I know if my dwelling has damage
An engineer’s report in accordance with I.S. 465:2018 is required to demonstrate that your dwelling has been damaged. This report must be carried out by an engineer who has the necessary professional experience and has completed specialist training. A list of these engineers can be found here
The register lists chartered engineers, who have the necessary direct professional experience, competence and specialist training in accordance with the requirements set out in 'I.S. 465:2018 - Assessment, testing and categorisation of damaged buildings incorporating concrete blocks containing certain deleterious materials’.
What is IS 465:2018?
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 informs 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 www.nsai.ie
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.
- 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);
- Describes methods for establishing the extent of the problem;
- Describes the scope of any testing required; and
- Categorises buildings, in accordance with the standard, providing competent persons with guidance on the appropriate measures to be taken.
