Abstract

Expansion of dark mudrocks as a consequence of sulphate development has been known for many years, generally occurring in low pH conditions. In buildings in Dublin, ground floor heave of up to 48 mm has been recorded within 5 years of construction, with some properties showing signs of distress even before the completion of the development. In each case the ground-bearing floor slabs rested on a pyritiferous aggregate with a pH of 8–10. A new model is proposed to explain why the effect of the expansion was evident in such a short period of time.
