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

Experts in their place. They will advise and recommend. The proposed solution works. Those who don't try it won't believe it. We can recommend this company.

Hello, today Mr. Douša was with us and installed the Drypol device for us, it was an excellent approach and a very professional lecture about the device and test boreholes for measuring humidity. It was all at a high level and professionalism. I praise and thank Mr. Douša. Karel Koucky.

Hello, our experience with the DryPol system has been very good. We were a little skeptical at first, but after installation and commissioning we changed our minds. The house started to dry out and not just by feel. First the smell of damp disappeared, later the plaster also dried out. Mr. Douša, who installed the system for us, explained everything to us, including later questions.We were completely convinced of the functionality of the system by the subsequent control measurements. We recommend the product and are convinced of its functionality. I would like to point out that this is an old house, without insulation, proper foundations and walls made of stone and wattle and daub.

Hello. I was looking for a way to dehumidify an old family house. I found a Drypol moisture removal device that was supposed to work wirelessly. Mr. Michal Douša came, explained everything, did some test drilling, recorded the values from the damp masonry, and installed the device. After three years, I had the masonry retested, and the measured values were much lower and therefore within tolerance. About a year and a half after installing the device, I also had the house completely dug up.
SMS: Three years after the installation of the device for drying the masonry, we asked to measure the humidity in the walls. In some places in the house, we had doubts that the device was working. After a careful measurement, which was carried out by Mr. Michal Douša, we were convinced that everything was in order. He again willingly explained everything to us. Thank you very much.

Comparison between electroosmosis and other
insulation methods
- suitable for small local cases
- construction work on the building required
- high price
- addresses moisture issues only where it is applied

- no construction work on the building
- affordable
- removes dampness throughout the building
- less suitable for small, localised cases (e.g. a damp corner)
- suitable with complete reconstruction
- construction work on the building required
- high price
- addresses moisture issues only where it is applied
