Our entrepreneurial origins? A small, German factory in 1865. Today, you’ll find our expertise everywhere, from the Golden Gate Bridge to the Panama Canal.How it all began
In 1865, son and father-in-law Eugen Dyckerhoff and Gottlieb Widmann began working together.

Our bridge-building legacy
In the 1880s, their factory developed into a construction company, which specialized in bridge building.

Our technology and expertise
In 1903, after a period of growth and R&D, they reinforced a concrete railway bridge with steel technology that would become the DYWIDAG Threadbar™

Geotechnics on a global scale
In the 1970s, DYWIDAG expanded into geotechnics to strengthen urban foundations—supporting rapid population growth.
