Abstract
Soon after the Ballymun Youth Facility was constructed in 2005, it became clear that the abnormally high number of “snagging” issues which had required remediation were not only re-appearing but increasing in amount and severity. The cause of the heave (up to some 10 mm/year) was the oxidation of pyrite in the hardcore beneath the ground-bearing floor slab and exterior paving. The nature and extent of the distress is discussed and the information obtained during the remediation process considered.
