Pat Ward will take on the top job from April 1, replacing Alain Bourguignon who has been promoted to area manager for North America and the UK by Aggregate Industries’ parent company, Holcim.
Ward, originally from Glasgow, has been with Aggregate Industries, which owns Bradstone, for nearly 20 years in various roles across their UK and US operations, after joining as a general manager in 1995.
He relocated to Denver, Colorado in 1999 as vice president of the West Central Region, later becoming senior vice president of the Western and Mid-Atlantic Region.
Bourguignon said of his appointment: "Pat is perfectly placed to hit the ground running as we respond to the demands of a returning construction market. Not only does he have an excellent knowledge of the sector, but he knows our own business inside out and will be a great cultural fit."
On the same day as Ward starts, non-executive board members Bill Bolsover - a former CEO - and fellow non-execs James Davis, Christine Farnish, Lord Fowler and Christopher Garnett will leave, as part of a move to consolidate Aggregate Industries' statutory board.
Bourguignon said: "Our departing board members have given us a great deal of support and direction over many years of service and I would like to thank each of them for their tireless commitment to Aggregate Industries.
"I’d particularly like to single out the significant contribution Bill Bolsover has made not just to the success of Aggregate Industries but also to the wider construction sector."
The company says the leadership changes will not affect the daily operation of the business.
