ATE MAX Black – Electromagnetic Anti-Damp Device for Wet Walls
Wall Drying – Premium solution for treating rising damp
Wall dampness is a common issue in homes, often caused by rising damp: moisture from the ground travels up through porous wall materials (bricks, stones, mortar), causing mold, saltpeter, odors, and loss of thermal insulation.
The ATE MAX Black is a powerful electromagnetic polarity inverter, designed to dry damp walls over time without injecting chemicals. With its wide coverage of 60 meters in diameter, it is ideal for large spaces or old buildings.
🔄 How does ATE MAX work?
Every wall naturally generates a potential difference with the ground, encouraging moisture to rise. The ATE MAX emits a very low-frequency electromagnetic field that reverses the polarity of water in the walls.
The water molecules reorient and flow back down toward the foundations, triggering a gradual and natural drying of materials, without damaging the building structure.

📊 Results and Effectiveness
When installed properly and following our recommendations, wall drying usually takes between 18 and 24 months, depending on the building layout.
🛠️ Installation Guidelines
-
Mount at 30 cm to 1 m from the floor, on a damp load-bearing wall (never on plasterboard or wall lining)
-
Keep at least 1.50 m away from any electronic device
-
The ATE MAX must remain plugged in continuously (very low power consumption)
-
Do not move the device once installed
💡 For Best Results:
-
Remove film-forming coatings:
Remove any waterproof paint or coating about 10 cm above damaged areas so the wall can “breathe.” -
Ensure proper ventilation:
Install or check for natural/mechanical ventilation (doors undercut by 1.5–2 cm, air inlets on windows). -
After drying:
Brush off salts from the wall surface. Use lime-based render with anti-salt additive to prevent future dampness. -
Install drainage if needed:
If lateral water infiltration exists, drainage may be necessary to prevent hydrostatic pressure from bringing moisture back.
❗ Good to Know
The ATE MAX system is designed to treat rising damp. It does not replace:
-
Treatment for water infiltration through cracks or leaks
-
Handling of mold or flood damage
These issues should be addressed separately for optimal results.







Mariab-Avis Leroy merlin –
The ATE device works very well. The humidity in my walls disappeared within a few months. Very satisfied, I highly recommend it.
