Michal Macháč
Expert in drying buildings and author of a technical solutionDo you have a question about the Drypol® system or a service?
Ask anythingIt is a basement under an apartment building. It is a whole cellar of 20x20 meters, which has several rooms and a wide range of uses. One part is used for skateboarding, another part has billiards, table tennis, a kitchen, a workshop, a warehouse and other rooms. And everything is 4 meters below ground level. There is little ventilation, there is mold, salt on the surface of the walls and wetness everywhere. The easiest way to deal with rising moisture in the masonry and finally, after other futile attempts, to start drying the masonry, is to use our DryPol® 30m moisture removal device. And because the owner wanted to be sure that drying began to take effect as soon as possible, on our recommendation and at his express request, we installed 2 of our DryPol® devices with fine wireless electroosmosis.

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.
