 Electromagnetic polarity reversal system against moisture IPE STOP ONE

The Electromagnetic Polarity Inverter (IPE) STOP ONE, a certified product of French origin, effectively combats wall moisture. It comes in the form of a compact unit that connects to a ground socket and can be placed or fixed in the damp area without requiring any masonry work. The device’s coverage ranges from 30 m² to several hundred square meters, depending on the installed version. By emitting very low-frequency waves, our Electromagnetic Polarity Inverter IPE STOP ONE reverses polarity and moves water molecules towards the ground, thus preventing rising damp. Moisture caused by the upward movement of water is permanently redirected towards the building’s foundations (between 18 and 24 months, depending on the building’s specifications and adherence to recommendations). Renovating with the IPE STOP ONE, a polarity inverter against moisture, is suitable for all buildings and houses with damp walls and floors.
