How does our device work?

The functionality of our device is based on a phenomenon called Osmo technology. Thanks to this, the OsmoDry® system offers rehabilitation without constructive intervention within walls, the whole problem is solved in a non-invasive way and without complications. So, there is no need for undercutting masonry or the use of electrodes.

The device generates electromagnetic pulses which work on a damp building. The electromagnetic field which it generates affects the water molecules inside walls and pushes them down, back into the soil. Thanks to this, masonry rehabilitation has never been easier. All you have to do is place the device within the building. Its installation consists of drilling several wall plugs into your damp masonry so that an OsmoDry® device can be hung and subsequently plugged it into your power supply. Then OsmoDry® device is fully functional. Osmo wall drying technology is a convenient solution for annoying problems. If you would prefer the device to be invisible, it can be easily customised to suit the building’s interior.

What's Osmo technology?

OsmoDry® uses active Osmo technology to allow for a non-invasive and electrodes-free masonry drying process. The device pushes water back into the soil and therefore eliminates moisture in your walls. Don’t worry, Osmo technology isn’t harmful, the electromagnetic field has no effect on human health and it’s absolutely harmless to living organisms.

Where can the system be used?

The OsmoDry® system offers solutions for the following types of properties:

  • Family houses
  • Recreational facilities
  • Residential dwellings
  • Civic facilities
  • Industrial buildings
  • Churches / all listed buildings

For all types of building materials such as brick masonry, stone masonry, bricks, concrete structures, or combined-mixed masonry. For above-ground as well as underground constructions (i.e. the ground floor of building and cellars).

Are you sceptical about the claimed effectiveness of OsmoDry technology?

Negative reviews about electro-osmosis technology have two sources: one is a wrong diagnosis of rising damp prior to the installation of electro-osmosis devices, and the other is poor quality devices and installation.

OsmoDry device is an innovative and reliable solution. Moisture readings are taken at the time of installation and controlled readings are conducted 12 months later. Our results proof the effectiveness of this device. On average we reduce the humidity of buildings by 59%. To give you complete peace of mind we offer a 100% money back guarantee*.

Our Victorian property had a damp and smelly cellar with mold growing on the walls. We had 1st Class EcoDry install the OsmoDry system and within days the humidity began to reduce.
​My experience is very positive - the technician was great and the Company communicated fully throughout the process. Plus we now don't have a mold problem!

Dan's home was dehumidified by 67%
