The Pyrite Resolution Act 2013 provides for the making of a pyrite remediation scheme by the Pyrite Resolution Board for certain dwellings affected by significant pyrite damage. The pyrite remediation scheme is a scheme of “last resort” and is limited in its application and scope. The scheme is applicable to dwellings which are subject to significant damage attributable to pyritic heave established in accordance with I.S. 398-1:2013 - Reactive pyrite in sub-floor hardcore material – Part 1: Testing and categorisation protocol. In addition, applicants under the scheme must be able to demonstrate to the Board that they have no practicable options, other than under the scheme, to secure the remediation of their homes. It is a condition of eligibility under the scheme that an application to the Board must be accompanied by a Building Condition Assessment with a Damage Condition Rating of 2. An extension, used for habitable purposes, is considered to be a dwelling for the purposes of the Pyrite Resolution Act 2013, and the implementation of the pyrite remediation scheme.
