A Legacy of Excellence

Our journey is deeply rooted in the rich history of McGraths Limestone (Cong) Ltd, a family-owned company with over 60 years of experience in the industry.

Established in the early 1960s by Michael McGrath Snr, the company began as a limestone quarry in Cong, Co. Mayo.

The business expanded its offerings to include aggregates, ready-mix concrete, asphalt, and specialized products like liquid screed , self-compacting concrete, and bead screed insulation.
