The prestressed concrete technique for the Dapsens factory was used not only on the approximately seventeen-meter-high silos but also on the passerelle that connected the new silos with four older reinforced concrete silos from 1925.

In the 1950s, a unique construction was added. An umbrella-shaped roof was built at the parking lot in front of the silos, resting on one star-shaped pillar. Under the roof, truck drivers could load and unload sand and cement without getting wet.
