ATE and ATG wall-drying devices – Solutions against damp and rising damp
Solutions against damp and rising damp.
We offer innovative solutions to dry out walls and treat damp. Our main products, the ATE models, are designed to stop rising damp at the source and protect your home over the long term.
Our electromagnetic polarity inverters emit electrical pulses into walls and floors. These waves act on water molecules, encouraging them to move back down into the ground, effectively stopping rising damp.
Our ATG polarity inverters use geomagnetic technology. They work without an electrical connection and require no maintenance. By using the Earth’s natural magnetic field, they provide an autonomous and discreet solution to dry out your walls.
All our products are designed and manufactured in France, ensuring a high level of quality and reliability. We sell our solutions directly on our website, with no middlemen and at factory prices, to offer you the best rate.

The ATE uses advanced electromagnetic technology to prevent rising damp and gradually dry out your walls.
This electromagnetic polarity inverter is an effective solution for treating capillary moisture in homes.
Easy to install and fully eco-friendly—unlike chemical resin injection—the ATE acts directly on the walls by altering the electromagnetic polarity within the structure.
The ATE is an electromagnetic device that runs on electricity. It is generally recommended as the first choice.
The ATG is a geomagnetic device, fully autonomous and does not require electricity. It is particularly well suited for second homes or public buildings, where a permanent electrical connection is not always possible.
“ATE LC15”: small areas (15 m radius).
“ATE LC30”: whole homes (30 m radius).
“ATE MAX”: large buildings (60 m radius), much more powerful and suitable for all applications.
“ATE Pulse”: same power as the LC30 with a modern design.
All models use Humidistop® electromagnetic technology, come with a 10-year warranty, and are made in France.
“ATG LC15”: small areas (15 m radius).
“ATG LC30”: whole homes (30 m radius).
“ATG MAX”: large buildings (60 m radius), more powerful and suitable for all applications.
All models are geomagnetic polarity inverters for wall dampness, come with a 10-year warranty, and are made in France.
The ATE device should be installed at the bottom of a damp load-bearing wall, preferably in the center of the area to be treated. It must be mounted on a flat surface, directly onto the wall and not on a lining/partition. Avoid obstacles that could limit the spread of the electromagnetic field. Following the instructions in the user manual ensures optimal effectiveness and long-lasting drying.
We recommend the electric ATE because it is faster and more powerful than a geomagnetic model. It works as soon as it is plugged in and generates a stable electromagnetic field that effectively stops rising damp. It is the most suitable solution for very damp walls or buildings that require a more intensive treatment. Easy to install and maintenance-free, it delivers visible results more quickly.
No, we do not carry out home visits or on-site diagnostics.
These visits are often indirectly included in the final quote by some companies, which leads to unnecessary extra costs for the customer.
Our devices, backed by a 10-year warranty, effectively treat rising damp caused by capillary action.
To advise you accurately, you simply need to send us a few photos of your walls. We can then quickly guide you toward the most suitable model, at no additional cost.
