our background


Learn about our history and team.
McGraths Limestone (Cong) Ltd is a 100% family owned & operated company with over 60 years experience in the business.
Quarrying started in the Cong area in the 1950’s due to the introduction of the subsidy for the haulage of Ground Limestone for agricultural purposes. Mr Michael McGrath Snr, father of the current owners, purchased the quarry in the early 60’s from the Glynn family on an area of about 7 acres.

The quarry has grown today to approximately 180 acres. Michael McGrath Snr produced only Limestone from the quarry up until his sudden death in 1970 at the age of 49. His wife Mary McGrath ran the business for a period of three years until Michael and John Joe took over its running which continues to this present day.

The business has expanded and grown every since, firstly it extended to the manufacturing of stone and aggregates for the building trade and local County Councils. In 1982 the company began producing ready mix concrete and concrete blocks and in 1995 saw the quarry exporting Weathered Limestone Rockery stone to mainland England where it is widely used by gardening centres and local authorities for landscaping purposes. Again in 1998 saw the company expanding as McGraths purchased a modern Asphalt Manufacturing Plant. Production, contract laying and civil engineering projects are all now a feature of McGraths Limestone.

In more recent times the company added an extension to their limestone facility by installing a state-of-the-art limestone fines Filler Plant for the production of calcium carbonates supplying flours and grits for glass manufacturing, agricultural feeds and industrial industries in both Ireland and Europe.

The quarry has remained a family affair with four sons and one daughter of the late Michael McGrath snr, and seven grandchildren and three great-grandchildren now working in the business.

The company has followed the principles laid down by its founder, Michael McGrath Snr who believed in a set of core values – honesty, integrity and respect for people. We also firmly believe in the fundamental importance of trust, openness, teamwork and professionalism, and pride in what we do.

These guiding principles have seen the company grow to one of the most important employers within 20 kilometer radius of the works, and are now considered an integral part of this rural community. As part of the business principles, we are committed to contribute to sustainable development, which requires balancing short and long term interests, integrating economic, environmental and social considerations into business decision-making on a daily basis.
