Building solutions specialist Holcim UK has acquired London-based construction waste management company Thames Materials. The acquisition is aimed at reinforcing Holcim UK’s standing in the recycling and construction demolition materials (CDM) market in London and surrounding areas.
Founded in 1995, Uxbridge-headquartered Thames Materials has become a major independent construction waste management company, operating a fleet of 62 vehicles and employing 90 staff. The firm specialises in the removal, haulage and recycling of construction site waste in London and surrounding counties.
In addition to its Uxbridge headquarters, the company has a 12-acre facility in Harefield, from which it conducts its recycling operations. This site recently saw its annual permitted processing capacity increase to 750,000 tonnes.
Lee Sleight, Chief Executive of Holcim UK, said that the acquisition strengthens the group’s presence in the London-construction market, while aligning with its “ambition of making sustainable construction a reality as we work towards becoming the leading UK provider of sustainable solutions.”
He continued: "Thames also has a great synergy with our existing recycling and construction demolition materials business in the East of London, and the acquisition will allow us to develop our services and reach to support the move to a more circular economy - especially with the need for greater use of recycled or reused materials in projects within the capital. By 2030, we have set ourselves a target to process 6.5 million tonnes of CDM annually."
Martin Clarke, Managing Director of Thames Materials, said: "This move allows us to continue on our growth trajectory and expand both our capacity and offering. Holcim is a market leader in the UK and internationally with a clearly articulated vision for circularity and sustainability and we are excited to be a part of that."
In accounts for the year to October 31 2024, Thames Materials Limited reported turnover of around £30 million, down from £32.9 million a year earlier, but increased its operating profits from £2 million to approximately £2.4 million.
