One can work with plastic and still have iron principles.


If sealing demands are high, we feel particularly comfortable.


We make your brand a success and discreetly remain in the background.

Private Label

We are happy to discuss product colours with you. But our electricity stays blue.


The perfect seal is yours.
We just manufacture them.

We manufacture exclusively in Germany, guarantee top quality and absolute discretion. We ship products and packaging with the brand logos of our customers.

In all that we do for you, the name Watermann Polyworks is always in the background.

You will find Watermann Polyworks everywhere you find construction and sealing. On behalf of our renowned customers from the international building supplies industry, we produce a wide range of sealing tapes, waterproofing membranes and corresponding system components such as sealing collars and corner tape.
