    DescriptionDonegal TD Charles Ward has welcomed the revised defective concrete block standard I.S. 465:2026 as ‘significant scientific progress.’

    The revised standard was published this week with homeowners and campaigners waiting patiently on the changes.

    The standard relates to the assessment, testing and categorisation of damaged buildings incorporating concrete blocks containing certain deleterious materials.

    The revised standard reflects a more advanced understanding of the complex causes of concrete block deterioration, including the role of iron sulfides, free mica, moisture and long term degradation processes.
