Our Company

We are based in Siegen, situated at the heart of the Siegen-Wittgenstein region and on the fringe of the Rothaargebirge. Siegen is home to nearly 100.000 people and is a vibrant city with a new university and a renowned conference venue. 

Our construction company Drössler and its affiliated factory of prefabricated parts employs over 180 members of staff and celebrates its 75th anniversary in 2007. An essential component of our service range is tank construction, an area that we can look back on 25 years of success.

Our prestressed concrete tanks are not only well-known throughout Germany, but also have become a product, which stands for reliability, security and the maximum quality and are supported by a high level of customer satisfaction.
