The UK & Ireland region, led by Michael Roddy, geographically covers England, Ireland, Wales and the Channel Islands. The region is predominantly focused on the construction industry, which represents 77% of its revenue, with core product offerings in the construction market including pre-cast concrete, concrete products, ready-mix concrete, asphalt and surfacing, dimension stone and aggregates. Through the CRH Lime Acquisitions in 2024, the UK & Ireland region expanded into industrial and environmental markets, with the additions of Clogrennane in Ireland in January 2024 and Buxton in England in March 2024.
