Geomagnetic Wall Drying System ATG LC30 WHITE – Wall Drying and Rising Damp
Wall drying without electricity – A natural and long-lasting solution against damp
It is an anti-damp device designed as a wall-drying solution to combat wall dampness linked to rising damp. This natural phenomenon occurs when groundwater rises through porous materials such as brick or stone, leaving walls damp over time.
It acts at the source thanks to a passive geomagnetic field that aims to reverse the polarity of water molecules, supporting a gradual reduction in rising moisture.
Its main advantage: it works without electricity, without batteries and without maintenance. A natural, autonomous and discreet approach, ideal if you are looking for a long-lasting solution against rising damp without invasive work.
Key features:
Action radius: 15 metres (30 m diameter)
Passive geomagnetic technology
No electromagnetic wave emissions
No wiring, no battery, no energy consumption
Quick and easy installation
Wall mounting recommended (adhesive or glue)
Made in France – 10-year warranty
Benefits of the geomagnetic ATG LC30
✅ Effectively stops rising damp at the source
✅ Protects walls, ceilings, floors, paintwork and parquet
✅ Compatible with all types of buildings (homes, basements, garages, churches, etc.)
✅ Improves thermal comfort and reduces heating bills
✅ No technical intervention required – simply install the device and follow the instructions
Best practices for maximum effectiveness
Installation on a shelf or inside a cabinet (under conditions)
This system can be placed on a shelf or inside a closed piece of furniture (wardrobe, cupboard) on the ground floor, under these conditions:
The support must be stable and secured to prevent any movement
The device must be firmly secured with strong double-sided tape or a stable base
Position between 1.50 m and 2.00 m from the floor
At least 1.50 m away from any electrical source (except standard wall sockets)
Oriented towards magnetic north (compass or app)
Once installed, the device must not be moved.
It is not necessary to place it directly on a damp wall. Positioning it in the centre of the treated area often ensures optimal distribution of the geomagnetic field.
Ventilation
Ensure adequate ventilation in the home
Install mechanical ventilation (VMC) if necessary
Check that doors have the correct clearance (1.5–2 cm)
Add window vents if needed
Preparatory work
Remove waterproof coverings at the base of the wall (10 cm above the damp marks)
Wait 18 to 24 months for complete drying before any renovation
Wall restoration
Brush off salts on the surface
Redo renders/plaster with a lime-based mortar and an anti-salt additive for long-lasting protection
Drainage (in case of lateral water ingress)
Install a perimeter drain to prevent water accumulation around the foundations
Important note
It is designed to treat rising damp only. It does not replace:
Waterproofing against water ingress from cracks or sloping ground
Managing damage caused by flooding
Treating mould already present on the surface
➡️ These issues must be handled separately to ensure complete protection.

« I bought and installed an ATG30 device two years ago. Things really are much better, although some more time is needed; the damp had been there for so long. I am satisfied. »
