Developing solutions? With pleasure

Others call it pioneering work. We call it day-to-day business when you want to make a difference:

Thus, we never disregard our responsibility and have contributed significantly to the spread of the "integrated seal" as well as to its anchoring in all quality guidelines and standards. This is how we bundle your interests and continue to help define the standard level of sealing technology.

In this way, our innovations do not have any role models, but it is nice when they have become some through demanding structures or large construction sites - as in the case of the Emscher Canal, the large-diameter pipes in the jacking area or the special compounds made of NBR for airports.

Here, constant presence on site on the one hand and direct exchange with our long-standing customers and the engineering offices for tomorrow on the other hand are among the success factors of an integrative potential expansion. With more than 30 different sealing profiles in the standard range as well as numerous special profiles, we can cover all requirements and set a good example - sometimes with small, sometimes with big steps.

But always made for generations.


Best quality is no coincidence

Since the technical requirements of the industry demand a high degree of quality and functional reliability, DS Dichtungstechnik's quality management works strictly in accordance with DIN EN ISO 9001:2015, as well as all applicable standards and quality guidelines, such as QR 4060. In addition to a high degree of internal self-responsibility, the products are also tested and monitored by international institutes. Regarding the quality of the products, DS always strives for a certain perfectionism for you.

A perfectionism for which we are happy to be held accountable in order to give you the ultimate: a good feeling.
