Gyproc Ireland has officially commenced work on an extension to its gypsum quarry, an investment aimed at securing the supply of a key construction material for the Irish market for decades to come.
The project reached a major milestone with an official sod-turning ceremony attended by representatives of Gyproc and its parent company Saint-Gobain, project contractors, local government officials and Minister of State Niamh Smyth.
The extension is intended to support the long-term operation of Gyproc’s Irish manufacturing business and the continued domestic supply of gypsum. The mineral is the principal raw material used to manufacture plaster and plasterboard for housing, schools, hospitals, commercial buildings and public infrastructure.
Work is beginning as Gyproc marks 90 years of operations in Ireland. The company said the project would extend the contribution of a locally sourced natural resource to Irish manufacturing, construction and skilled employment.
Kieran Holohan, Managing Director of Saint-Gobain Ireland, said the quarry had been the starting point for 90 years of industrial activity, employment and construction material production.
“Today’s investment ensures that this contribution can continue for the next generation, supporting the people, communities and sectors that rely on high-quality Irish-sourced and Irish-made building solutions,” he said.
The ceremony was also attended by John Duffy, Mining and Manufacturing Director at Gyproc Ireland; Robert Burns, Chief Executive of Monaghan County Council; and Aidan Campbell, Cathaoirleach of Monaghan County Council.
Minister of State for Trade Promotion, Artificial Intelligence and Digital Transformation Niamh Smyth said the investment demonstrated confidence in the local community and the future of Irish industry.
“Gyproc’s investment will help secure jobs, strengthen supply chains and support the delivery of the homes, schools, healthcare facilities and infrastructure that Ireland needs,” she said.
The project carries wider importance for the construction supply chain at a time when Ireland is seeking to accelerate housing and infrastructure delivery. Maintaining a secure domestic source of essential building materials can reduce exposure to international supply disruption and support greater certainty for manufacturers, contractors and developers.
Gyproc said the quarry works would be progressed safely and responsibly in collaboration with its contractors, partners and local stakeholders.
The business, which operates as part of Saint-Gobain, is also continuing to invest in manufacturing innovation and more sustainable construction products as it responds to changing technical and environmental requirements across the Irish building industry.
