The firm founded in the late 1980s has two large asphalt plants in the Port of Tyne and the Port of Sunderland.

Aggregate industries said the acquisition would allow it to strengthen its market position in the region and support the much needed major infrastructure schemes.

Guy Edwards, CEO of Aggregate Industries UK, said: “We have been very impressed with the Northumbrian Roads business.

“They share the same values, including a strong health and safety culture and their expertise and approach to customer service, so I believe that they will be a great addition to our portfolio.

“Throughout the pandemic we have been proud to help keep Britain running and this acquisition will allow us to play an important part in the North East infrastructure schemes.”

Sean Lynch, managing director of Northumbrian Roads, said: “Ever since the company was founded by my father John Lynch and business partner George Barton over 31 years ago, we have progressively grown the company, focusing on strong relations with our customers, teamwork and innovation.

“We are now excited to continue our journey under the ownership of Aggregate Industries, as this partnership will allow us to further develop our business, while maintaining our ambition to be the preferred surfacing partner for all our customers.”
