The foundations for highly innovative sleeper concepts and their economic production were laid in the beginnings of the Dyckerhoff & Widmann group of companies.
P-TEC now maintains this tradition, and continues to develop these systems. Today, we have a respected name. Trend-setting technology, progressive thinking, and pronounced customer-orientation stand behind the name P-TEC.
