Takeover of Bitbau DÖRR by Sika.


After approval by the competition authorities, our company has now been officially taken over by Sika AG, a globally active and leading company in specialty chemicals.



As before, Bitbau DÖRR GmbH will continue to operate separately and the Bitbau DÖRR brand will still continue to exist.

Your contacts in sales, customer service and the technical department will all remain unchanged and as in the past, they will continue to take care of your needs as best as possible.


We are convinced that through the joint path of our two companies we will be able to meet your requirements in the future even better through a wide range of high-quality and durable waterproofing systems as well as our well-known high quality of service.



If you have any questions do not hesitate to contact us. We would like to thank you for your trust and look forward to continue a successful partnership!
