MCGRATH'S LIMESTONE (CONG) LIMITED

McGrath's Limestone (Cong) Limited is a family-run enterprise that has been supplying high-quality limestone-derived products for over 60 years. Based in Cong, County Mayo, the company harvests pure limestone from its Cregaree quarry and turns it into a wide range of construction and agricultural solutions.

Their core offering includes ready-mix concrete and fully-fired concrete blocks, as well as road-surfacing materials such as halt and macadam. In the stone division they provide crushed limestone aggregates, filling and hardcore for a variety of civil-engineering projects. The agricultural arm supplies calcium carbonate products - notably the fine-textured Grolime - which improve soil pH, enhance fertilizer availability and boost pasture health. McGrath's also markets Cemfloor flooring systems and a selection of specialised calcium-carbonate grades (Congcal G3 Grade 1 & 2).

Guided by values of honesty, integrity and respect for people, the business places sustainability at the heart of its operations, ensuring environmentally responsible extraction and production while delivering reliable, prompt service to contractors, farmers and developers across the west of Ireland.
