Building expertise since 1911 In 2011 we celebrated our 100th anniversary. A long time in which a lot has changed in construction too. We gladly accepted new challenges and continued to develop. Today we have more skills, greater flexibility and are based on the latest technology. The foundation of our work was and is solid craftsmanship, our reliable employees and the trusting relationship with our loyal customers. Traditions that you can also rely on in the future! © 2011 HESS GmbH Home | Contact | imprint
