This Irish Standard:

a) establishes a protocol for assessing and determining whether a building has been damaged by concrete blocks containing excessive amounts of certain deleterious materials (aggregate containing free or unbound muscovite mica or potentially deleterious quantities of pyrite);
b) describes methods for establishing the extent of the problem and categorises dwellings;
c) describes the scope of any testing required and evaluation of the findings; and
d) provides the Chartered Engineer with guidance on the selection of appropriate remedial works to be undertaken.
This Irish Standard is not intended for:
a) the specification, manufacture and testing for compliance of new concrete blocks (aggregate concrete masonry units) in accordance with I.S. EN 771‐3 (and associated testing Standards) or as a replacement to the guidance provided in Standard Recommendation S.R. 325; and
b) dwellings not exhibiting structural damage consistent with defective concrete blocks, see Clause 4.

The protocol addresses the issue of defective concrete blocks but does not rule out other potential defects in a dwelling which may for other reasons require remedial attention. 

The use of this Irish Standard is limited to concrete block‐built dwellings exhibiting signs of distress consistent with damage caused by blocks containing certain deleterious materials.

This sample certificate (Annex F of I.S. 398-1:2017) includes clarification notes to Building Categories B and C as outlined in the Foreword of I.S. 398-1:2017.

This certificate is issued and signed in accordance with I.S. 398-1:2017 Reactive pyrite in sub-floor hardcore material – Part 1: Testing and Categorisation protocol to the building. 

This certificate is based on and shall be read in conjunction with the associated Report of the Building Condition Assessment and the Professional Geologist/Chartered Geotechnical Engineer’s Report on the classification of the hardcore.

The scope of this Standard Recommendation addresses the energy retrofit of the building fabric and services of detached, semi-detached and terraced dwellings of not more than three stories.

The main purpose of this S.R. is to provide technical guidance on the design and installation of retrofit measures to improve energy efficiency while: -

  • maintaining the fi re safety performance of dwellings;
  • ensuring structural integrity and acoustic performance;
  • maintaining healthy internal environments;
  • controlling the movement of moisture.

The S.R. addresses the following points:

  • retrofit measures that are suitable for typical forms of construction in Irish dwellings;
  • an explanation of building science relevant to retrofit;
  • good practice for building fabric measures;
  • good practice for building services measures.

Whilst the scope of this S.R. is intended for dwellings some aspects of this S.R. may be applied to other buildings as appropriate.

This S.R. does not apply to works to an existing building which is a “protected structure” or a “proposed protected structure” within the meaning of the Planning and Development Act 2000 (No. 30 of 2000) and traditional buildings.

The guidance in this S.R. may not be appropriate for dwellings which, although not protected structures or proposed protected structures, may be of architectural or historical interest.

Some traditional buildings perform and respond to the outside/inside environment differently from more modern/mid-to-late 20th Century buildings.

In general this S.R. does not provide guidance on the use of renewable energy sources in retrofit projects.

NOTE Further guidance on suitable energy efficient retrofit measures for traditional and historic buildings is contained in ‘Energy Efficiency in Traditional Buildings’, DEHLG.
