A transformative acquisition creating a global market leader

Munich, Germany, June 12, 2026 (GLOBE NEWSWIRE) — DYWIDAG Group (“DYWIDAG”), a leading global provider of geotechnical products, post-tensioning services and stay-cable solution services today announces it has entered into a definitive agreement to acquire Interspan (Holdings) Pty Limited (“Interspan”) a leading provider of post-tensioning and concrete repair & strengthening services in Australia, UK and Europe.
