Wall drying device - ATG geomagnetic polarity inverter against moisture in walls
Discover the ATG Range
Discover the ATG range, French-made geomagnetic devices designed to treat wall dampness and reduce rising damp. Available in three power levels:
🔹 ATG LC15: 15 m diameter
🔹 ATG LC30: 30 m diameter
🔹 ATG MAX: 30 m radius (up to 60 m diameter), ideal for large homes or technical buildings
These polarity inverters operate without electricity, batteries, or maintenance. Suitable for all building types: private homes, agricultural buildings, technical facilities or heritage sites.
💧 How the geomagnetic technology works
ATG devices use natural geomagnetic fields to alter the distribution of water molecules in building materials. This physical action gradually draws moisture downward, enabling the natural drying of walls — without injections or chemicals.
🛠️ Simple, autonomous installation
Each model comes ready to install: simply fix the cylindrical unit to a load-bearing wall between 1.50 and 2 metres high, facing north. No wiring required. Efficiency depends on following the installation guidelines.

How does our geomagnetic system work against capillary rising?
Choose ATG, the French solution against wall moisture | Easy and autonomous installation | No need for electricity or batteries. Say goodbye to moisture in your home with ATG, the French geomagnetic device that requires no construction work! This autonomous cylindrical box exclusively uses electromagnetic fields to reverse the polarity of water molecules, enabling the natural evaporation of moisture.
By following our installation and usage recommendations, users can typically observe significant results within 18 to 24 months. Renovation with IPG GEOSTOP, a polarity inverter against moisture, is suitable for all buildings and homes with damp walls and floors.
The result
A living solution in which damp walls are quickly dried to provide optimal comfort and improve air quality, promoting better health. With this solution, you can bid farewell to nuisances such as saltpeter, damp walls, odors, and high maintenance and repair costs. Key features include a rapid wall drying process with no impact on health and a solution that addresses the cause of capillary rising. Furthermore, reduced humidity in the dwelling will lead to lower heating costs.
ATG offers 3 different models of our geomagnetic polarity inverter
Wall Drying: Innovative Solution Against Rising Damp with the ATG Geomagnetic Polarity Reverser
Rising damp, also known as capillary rise, is a common phenomenon in older or poorly protected buildings. It occurs when water from the ground travels upward through the porous materials of walls (such as stone, brick, or concrete), causing structural damage, mold growth, and deterioration of indoor air quality. To address this effectively, the ATG geomagnetic polarity reverser offers a simple, durable, and non-invasive solution.
This Made in France device acts directly on the root cause of the issue. By influencing the geomagnetic fields present around damp walls, it halts the upward movement of water by reversing its polarity. As a result, the moisture gradually returns to the ground, and the walls dry out naturally over a period of 18 to 24 months (depending on the building’s characteristics and adherence to recommendations).
Advantages of the ATG Geomagnetic System
Emits no artificial electromagnetic waves
Autonomous operation, with no battery or electrical power required
Long-lasting solution that addresses the root cause rather than just the symptoms
Simple and quick installation, with no drilling, construction work, or professional help needed
Effective on all types of walls: stone, brick, concrete, rammed earth
Capable of treating the entire structure: walls, floors, pillars, basements, etc.
Helps reduce ambient humidity and improves thermal comfort
Contributes to lower heating costs by reducing the conductivity of damp walls

Made in France
How the ATG Geomagnetic Polarity Reverser Works
The device captures the natural electromagnetic fields generated by the moisture present in the ground and within the walls. It emits a counter-field with opposite polarity, thereby neutralizing the capillary rise. By eliminating the electrical charge responsible for water migration, the system allows moisture to gradually return to the ground.
Thanks to its passive technology, the ATG operates without any power supply or maintenance, as long as it remains correctly positioned in the damp area to be treated.
Results are typically visible within 18 to 24 months (depending on the building’s characteristics and adherence to recommendations).
Instructions for Use and Installation Recommendations for the ATG
- Install the device at a minimum distance of 1.50 meters from any electrical source, except for standard wall outlets.
- Position the device at a height between 1.50 and 2.00 meters above the floor.
- Secure the device firmly using double-sided adhesive tape or glue (no drilling required). It should not be moved once installed.
- Orient the device to face north using a compass or a compass app on a smartphone.
Installation can be done on any wall of the building, provided that the device’s effective range covers the entire area to be treated (check the maximum diagonal to be covered).
For optimal drying, it is recommended to:
Remove any film-forming coatings or paints at the base of the walls,
Ensure proper ventilation of the space,
Restore the walls using mineral-based, salt-resistant renders,
Install a drainage system in case of lateral water infiltration.
⚠️ This device does not treat flooding, lateral water infiltration, or mold: additional treatment is required in such cases.
