Sydney-based Interspan brings 400-plus staff to DYWIDAG
German group DYWIDAG completed its acquisition of Interspan (Holdings) Pty Limited on 8 July 2026, adding a Sydney-headquartered engineering business with operations across Australia, the UK, Europe and Asia.
Combined proforma revenue at DYWIDAG and Interspan reached €465 million at the end of March 2026. EBITDA margins topped 10%.
Founded in 2006, Interspan employs more than 400 people and generates annual revenue of more than €75 million.
According to DYWIDAG, the purchase expands its core services in Australia and the UK. It adds post-tensioning, concrete repair and strengthening work in both markets.
Interspan runs as a vertically integrated engineering and construction business. Its teams deliver engineering, design and installation in-house for post-tensioning, structural strengthening and remediation on new and existing concrete structures.
Don Fraser and James Laws
Interspan founders Don Fraser and James Laws will stay with the business after completion. DYWIDAG expects them to help manage the transition and support strategic growth plans.
Hugh Pelham, chief executive of DYWIDAG, said: “Interspan is an exceptional business with a strong track record of customer satisfaction and financial performance.”
Meanwhile, DYWIDAG said Interspan’s repair and strengthening work could open new opportunities in America, the UK and Europe. It also expects substantial synergies through supply chain savings.
DYWIDAG funded the deal from existing cash resources and a bond tap under its senior secured bond framework. That Tap Issue raised €50 million, while Arctic Securities AS, filial Sverige, acted as sole bookrunner.
DYWIDAG provides geotechnical products, post-tensioning services and stay-cable solution services. Following the Interspan acquisition, the group said the deal marks a significant milestone in building an international market leader.
James Laws, joint founder of Interspan, said the deal would help accelerate growth in existing markets and support expansion into new ones.
On the advisory side, DYWIDAG used A&O Shearman LLP as legal counsel and EY Parthenon for financial and tax due diligence. Interspan worked with Greenstone Partners, Mont Lawyers and Magpie Advisory.
