In 1931, continuously rising demands caused the company management to erect a Thiele high performance kiln with a daily capacity of approx. 100 tonnes. At the time, cement was still delivered in 200 kg barrels. However, capacities were not able to meet the demand. Therefore, Wietersdorf invested in a modern Lepol rotary kiln with a daily capacity of 200 tonnes. Just before the end of the Second World War, the capacity of the works was once more fully exploited. In 1940, the state-controlled company “Verkaufsgemeinschaft Süd-Ost” requested that Wietersdorf deliver 71,000 tonnes of cement (this equalling 355 days work at maximum capacity). Financially speaking, these were interesting orders from the point of view of the owners, but from the proceeds so-called “donations” had to be made to the Third Reich, and 18.5% war tax had to be paid on top.
