special constructions

Demanding building types such as power stations, large industrial plants, dams or airports often require highly specialised special constructions. They place high demands on the safe and permanently leak-proof passage of pipes and cables when penetrating the building. As soon as pipes have unusual dimensions or special thermal, chemical or physical requirements exist, sealing systems as special constructions are the only solution. Only they can meet these individual conditions of the building. DOYMA has the know-how and experience of 60 years to develop and produce the best solution for your building. State-of-the-art design and manufacturing processes as well as professional simulation methods help and create safety when using DOYMA special constructions. And that with a 25-year guarantee on panel constructions.
