From 1st May 2022, Whitemountain Quarries Ltd, Lagan Asphalt Ltd, and Lagan Materials Ltd have rebranded as Breedon Ireland.
Since the acquisition in 2018 when the family of Irish companies became part of the Breedon Group, its Irish materials and contracting divisions continued to operate under the brands Lagan in ROI and Whitemountain in NI.

The company believes that it is now time for a more unified approach, with its main objective being to simplify the brand structure in Ireland and provide clearer communication to the industry and its stakeholders.

Brief History
Breedon Ireland’s Managing Director, Terry Lagan, set up the original Lagan Group business in ROI in 1989, which originally comprised an asphalt production & contracting division along with a bitumen emulsion production plant. The business developed from there to cover the entire island, with operations from Cork to Donegal and Galway to Dublin, becoming the largest independent producer of construction materials in ROI. Following the acquisition of the Lagan Group in 2018 he joined Breedon Group as Managing Director of Lagan, Breedon’s business in ROI.


The brand merger of Lagan and Whitemountain to Breedon Ireland will help to combine the Group’s talent, knowledge, and expertise. More robust governance processes mean Breedon, as a unit, can be resilient against future risk, protect the livelihoods and welfare of their employees and refine their sustainable business model to create more value for all stakeholders. The ultimate goal across the entire Breedon Group is to work together as one, all making a material difference.

Together, now bigger, now stronger, now Breedon.
