Expert in drying buildings and author of a technical solutionDo you have a question about the Drypol® system or a service?
Ask anythingIt is an apartment house with a basement, where almost all the walls were wet. The basement is unusually wet, also because there is no air circulation. That is why we advised the owners to arrange some ventilation, because it is a large cellar, it has over 3m high ceilings, it is closed and no air can flow anywhere. They plan to create some vents and maybe a window. However, we primarily deal with the humidity of the walls on the ground floor, because people live there for a long time and it is wet everywhere in the apartments (it can be clearly seen in the photos). There are two apartments on the ground floor and our DryPol® 30m device with fine wireless electroosmosis is in each of them.

Reviews and experiences of clients with the Drypol® system

I recommend, helpfulness, speed, everything was explained to us. Communication regarding Mr. Dousha was excellent.
Hello, I would like to take this opportunity to thank Mr. Bc. M. Douša for drying out my basement apartment in Prague and for his professional approach. I can only recommend this technology and services. Vodvářková, Prague
After installing the device, the measured humidity values decreased. Thanks also go to Bc. Michal Douša for the professional installation, careful control measurements and pleasant dealings. We recommend.
Mr. Douša, I want to thank you once again for the professional approach to the installation of the DRYPOL device from your company. I am very glad that you explained to me in detail the issue of humidity and things related to it. I really appreciate your time, which you fully devoted to me and I can already feel the changes that are already happening in the basement of our house (1 month since the installation). Every small change is a great joy for us. Have a good time, Jiří Kunc-Prague 5-Smíchov.
