Mike Stacey, former managing director of CPM, will remain with the business and join Marshalls' senior management team, reporting to chief executive Martyn Coffey.
Martyn Coffey said: “Marshalls' 2020 Strategy is to grow both organically and through carefully selected earnings enhancing bolt-on acquisitions with a particular focus on the identified growth areas of water management, security and mineral products. The acquisition of CPM represents a significant step towards achieving one of our strategic goals. CPM is a profitable business with a strong track record of quality and service, primarily targeting public sector and commercial end users and the acquisition will expand Marshalls' product range into below ground drainage. We expect the business to trade, initially as Marshalls CPM, within the wider Marshalls Group."
