Professional rising-damp treatment devices
Permanent solutions for damp walls and ascending moisture
Wall-drying devices ATE and ATG – Polarity inverter for damp walls and rising damp
ATE and ATG Help Humidité® – Over 13 years of expertise in humidity control
Since 2012, Help Humidité® has been designing and manufacturing professional wall-drying devices in France, intended for both homeowners and building professionals. Whether you want to protect your home, renovate an older property, or treat a commercial building, our solutions adapt to every need.
A complete range for all types of buildings
Electromagnetic technology (ATE):
ATE LC15, ATE LC30, and ATE MAX – Powerful and fast-acting devices that start working as soon as they are installed to stop rising damp.
Passive geomagnetic technology (ATG):
ATG LC15, ATG LC30, and ATG MAX – Devices with no electrical power supply, operating continuously and silently.
These polarity inverters are suitable for individual houses, cellars, old buildings, and recent constructions. They require no maintenance, produce no noise, and offer long-lasting effectiveness, proven in real-world conditions for over 10 years.
How our technology stops rising damp – without chemicals or major construction work
Rising damp occurs when water from the ground travels up through walls by capillary action. It is a natural phenomenon — but it can damage everything: plaster, paint, wood, and even your health. Unlike traditional methods that require drilling or injecting chemical products into the walls, Help Humidité works differently.
We use low-frequency electromagnetic or geomagnetic waves to reverse the polarity of water molecules. This prevents water from rising and allows the walls to dry naturally and permanently.
There is nothing to break. Nothing to recharge or maintain. You simply install the device — it then operates continuously, silently, day and night.
Protect your home from rising damp with a durable and eco-friendly solution
Are your walls damp, damaged, or giving off a musty smell?
Don’t let rising damp silently damage your home.
Help Humidité offers a certified, non-invasive solution that effectively combats ascending moisture thanks to advanced polarity-inversion technology — with no chemicals, no drilling, and no maintenance.
Our devices manufactured in Europe generate a magnetic or electromagnetic field that allows your walls to dry naturally over time, while protecting your home, your health, and your investment.

Electromagnetic polarity inverter – ATE LC15 | ATE LC30 | ATE MAX
Discover the ATE LC15, ATE LC30, and ATE MAX electromagnetic polarity inverters — certified devices manufactured in France, designed to effectively combat rising damp.
With their wide action range (from 15 to 60 metres), these systems deliver optimal performance at a competitive price.
Plug-and-play installation: no drilling or renovation work required. Simply plug the device into a grounded power outlet.
The low-frequency wave technology acts on the polarity of water molecules to limit capillary rise within the walls.
Improvements are generally observed between 18 and 24 months, provided that our installation recommendations are followed.
Ideal for houses, basements, garages, and heritage buildings facing moisture problems in walls or floors.

Expert advice – How to fight rising damp in your home
At Help Humidité, we offer cutting-edge solutions to eliminate moisture from walls using polarity-inversion technology.
Our flagship products — ATE LC15, LC30, and ATE MAX — are specifically designed to reverse rising damp and gradually dry your walls.
Explore our full range online and find the device that suits your needs.
Whether you are a homeowner, landlord, or building manager, our technology is designed to provide long-lasting protection for your property.
The ATE uses advanced electromagnetic technology to prevent rising damp and gradually dry your walls.
The electromagnetic polarity inverter is an effective solution for treating ascending moisture in homes.
Easy to install and completely eco-friendly — unlike chemical resin injection — the ATE acts directly on the walls by modifying the electromagnetic polarity within the structure.
The ATE is an electromagnetic device that operates using electricity. It is generally recommended as the first choice.
The ATG is a geomagnetic device, completely autonomous and electricity-free. It is particularly suitable 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 houses (30 m radius).
ATE MAX: large buildings (60 m radius), much more powerful and suitable for all cases.
ATE Pulse: same power as the LC30 with a modern design.
All devices operate using Help Humidité® electromagnetic technology, come with a 10-year warranty, and are manufactured in France.
ATG LC15: small areas (15 m radius).
ATG LC30: whole houses (30 m radius).
ATG MAX: large buildings (60 m radius), more powerful and suitable for all situations.
All models are geomagnetic polarity inverters for wall-moisture control, come with a 10-year warranty, and are manufactured in France.
The ATE device must be installed at the bottom of a damp load-bearing wall, preferably at the centre of the area to be treated. It must be fixed on a flat surface, directly on the wall and not on any cladding. Avoid obstacles that could limit the diffusion of the electromagnetic field. Following the instructions in the manual ensures optimal effectiveness and long-lasting drying.
We recommend the electrical ATE because it is faster and more powerful than a geomagnetic model. It starts working 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 requiring a more intensive treatment. Easy to install and maintenance-free, it provides visible results more quickly.
No, we do not carry out home diagnostics.

Our devices, guaranteed for 10 years, effectively treat capillary moisture.
To give you precise advice, you simply need to send us a few photos of your walls. This allows us to quickly guide you towards the most suitable model, without any extra charges.
