May was the man drafted-in to successfully turnaround McNicholas Construction in 2003 when the civils specialist ran into financial trouble.

Brian Harvey, CEO of Siteserv said, “Martin’s appointment is a signal of the ambitious expansion plans we have for DSL and other Siteserv companies.

“His wealth of experience and industry relationships will support our business strategy to broaden our offering in the UK and internationally.”

May said: “I’m delighted to be joining Siteserv’s board and to be appointed non-executive Chairman of DSL.

“Both companies have a track record of success that will provide a robust platform for the next phase in their evolution.

“I look forward to pursuing this new challenge, and helping to influence a strategy that will bring about significant growth.”

In his new role as non-executive Chairman of DSL,  May will be responsible for overseeing the execution and delivery of a strategy to broaden the company’s international footprint and range of services.

Services currently provided by DSL include access scaffolding, insulation services, asbestos removal, protective coatings, passive fire protection, and industrial painting.
