About
Trusted for Over 150 Years
Our mission is simple yet powerful: make structures safer, stronger, and smarter.
For more than 150 years, DYWIDAG has shaped the world’s infrastructure - from bridges and tunnels to dams and skyscrapers.
Founded in 1865 by Eugen Dyckerhoff and Gottlieb Widmann, DYWIDAG began as a small German workshop and quickly became a pioneer in construction. Trusted on the world’s most ambitious projects, we continue that legacy today - bringing intelligence and strength to the infrastructure millions rely on every day.
