Arcus announces strategic expansion of Workdry International with the acquisition of Vanderkamp Pompen

The acquisition expands Workdry’s pump rental solutions footprint into Europe and significantly bolsters its technical solutions capabilities 

London, United Kingdom, 8 February 2024 – Workdry International (Workdry) has acquired Netherlands-based temporary pumping solutions specialist Vanderkamp Group (Vanderkamp), partnering with Rick van der Kamp and his team to grow internationally and strengthen the combined group’s offering of rental solutions for the handling and treatment of water and wastewater.

The acquisition, backed by independent fund manager Arcus Infrastructure Partners (Arcus) as Workdry’s majority shareholder, will see Workdry immediately establishing a market-leading presence in pump rental solutions in the Netherlands and north-west Europe more broadly, while joining up with the world-class technical team at Vanderkamp to improve its engineered solutions offering across the entire business.

Vanderkamp’s operations in the Netherlands, including Vanderkamp Pompen and Vanderkamp Service, will continue under the name Vanderkamp – The Dutch Water Engineers, operating as the international pump rental solutions division of Workdry. The UK-based Vanderkamp activities will be gradually integrated into Workdry’s existing UK operations, including its market-leading Selwood pump rental solutions business.

Rick van der Kamp, currently CEO at Vanderkamp, will continue to lead the Vanderkamp business while also taking a senior management role within the Workdry group to promote technical excellence, build on his long history of water management innovation and drive international business development.

Richard Brown, CEO, Workdry International, said: “We have long been admirers of Vanderkamp, whose focus on technical excellence and outstanding service reflects our own values as a leader in engineered pumping solutions. Bringing Vanderkamp into the Workdry group increases our presence in Europe in line with our strategic growth ambitions, and enables us to provide both Selwood and Vanderkamp customers with access to an extended fleet, a comprehensive branch network and a growing team of pump rental solutions experts. I am delighted to welcome Rick and the team at Vanderkamp into the Workdry family.”

Rick van der Kamp said: “We are proud to join the Workdry family which will accelerate our global ambitions as The Dutch Water Engineers. With additional resources, Vanderkamp will continue to excel in what we do best – conceptualising and delivering cutting-edge solutions.

“As part of Workdry, we aim to expand our knowledge and technology, surpassing customer expectations. Equally important is providing certainty and stability to all stakeholders – employees, customers, and suppliers. This strengthens our leading position in the market of temporary pump solutions, retaining our down to earth, Dutch approach to solving complex problems with our typical Vanderkamp DNA.”

Jordan Cott, Partner at Arcus and Chair of Workdry, said: “We have a tremendous amount of respect for Rick and the business he has built over the past few decades, and are very pleased that he has decided to partner with us for this next chapter.

“This acquisition will serve as a stepping stone onto an exciting new growth trajectory for Workdry, providing a strong base for expansion into Europe and deepening the group’s core value proposition in engineered pump rental solutions. This acquisition fits perfectly within the Arcus value-add mid-market strategy of supporting market leading businesses on long-term value creation initiatives and builds on our successful track record of partnering with world-class entrepreneurs and family businesses.”
