Kilwaughter Minerals to 'continue ambitious growth journey’ after being acquired by multi-national group
The chief executive of Kilwaughter Minerals has welcomed the company’s acquisition by a multi-national group as an opportunity for continued growth.
The Larne-based quarry and mineral processor is to become part of Saint-Gobain group after a binding agreement was reached.


Saint-Gobain is a global leader in the design and manufacture of solutions for the construction industry and employs 160,000 people across 76 countries.
It has a wide-ranging portfolio of lightweight construction solutions for building facades and envelopes.
Gary Wilmot, CEO of Kilwaughter Minerals said: “We’re excited with the opportunity to join the Saint-Gobain group and continue Kilwaughter’s ambitious growth journey.
“Kilwaughter has a rich company culture and heritage, and our focus remains on delivering a leading customer experience, underpinned by our trusted brands. We look forward to the added synergy that Saint-Gobain will undoubtedly bring and sharing our passion for innovation, quality and excellence.
“We see the alignment of the vision and values between both companies as a strong building block for our teams and customers.”
Kilwaughter has its headquarters at its limestone quarry in Larne, from where it serves its construction and agriculture customers throughout the UK and Ireland, with distribution centres in Glasgow, Cork and St Helens.
Known for brands K Rend, K Systems and Kilwaughter Lime, the company has delivered continued success in recent years. To year end (April 2024), Kilwaughter generated revenues of circa £50m and has over 200 employees.
As per normal process, the acquisition has been forwarded to the Competition and Markets Authority with closing of the transaction expected in the first half 2025.
