DYWIDAG Group, the global provider of geotechnical products, post-tensioning services and stay-cable solution services today announces it has completed the acquisition of Interspan (Holdings) Pty Limited, the post-tensioning and concrete repair and strengthening services company with bases in Australia, UK and Europe.
Founded in 2006 and headquartered in Sydney, Interspan employs more than 400 people, has annual revenues in excess of £65 million. It is a vertically integrated specialist engineering and construction business that provides post-tensioning, structural strengthening, and remediation solutions for new and existing concrete structures, with engineering, design, and installation delivered in-house.
DYWIDAG says that Interspan represents a compelling strategic fit because it not only extends DYWIDAG’s core services in Australia and the UK to include post-tensioning and repair and strengthening services, but it also leverages Interspan’s strengths in repair and strengthening services to unlock new opportunities in America, UK, and Europe.
The founders of Interspan, Don Fraser and James Laws, will remain with the business post-completion in order to ensure a smooth transition and deliver on the strategic growth initiatives of the combined group.
The acquisition has been financed from existing cash resources and by issuing subsequent bonds issued under its existing senior secured bond framework with an issue size of EUR 50m (the “Tap Issue”). Arctic Securities AS, filial Sverige, acted as Sole Bookrunner.
The transaction is a highly significant milestone for DYWIDAG and will create an international market leader in the provision of its core services. As of the end March 2026, Dywidag and Interspan had combined proforma revenues of 465m euros with 10%+ EBITDA margins.
Hugh Pelham, CEO of DYWIDAG, commented:
“Interspan is an exceptional business with a strong track record of customer satisfaction and financial performance. The combination of Interspan and DYWIDAG reinforces our position as a global market leader in the provision of post tensioning, stay-cable solutions, geotechnical products and specialist repair and strengthening solutions”
James Laws, Joint founder of Interspan, commented:
“This transaction marks an exciting new chapter for Interspan. DYWIDAG is a global market leader and we see a clear strategic fit between our businesses. DYWIDAG’s international platform, technical capabilities and long-term investment mindset provide significant opportunities to accelerate Interspan’s growth in existing markets, expand into new markets and further enhance our offering to our clients.
“Don Fraser and I are incredibly proud of what the Interspan team has built and we look forward to working with DYWIDAG to take the business to the next level.”
