Our FAQ

A wall drying system that runs in accordance with the electro-physical principle of field inversion for the elimination of ground and wall moisture over the entire building area without any structural measures.

OMBRELLO® technology replaces defective or lacking moisture-proofing courses and eliminates rising moisture penetrating from the side of dry stone, concrete, brick and wooden walls. The capillary effect in walls is neutralized, which means that no moisture can rise up into or penetrate into the walls. The existing moisture returns to the soil. The original insulation value of the dry walls is then restored.

OMBRELLO® eliminates the cause of flaking paint and crumbling plaster, wall erosion, moldy odors, mildew, salt efflorescence and black stains on walls. High room humidity is lowered and resulting health risks such as allergies, colds, rheumatism etc. can be minimized.

OMBRELLO® can be used in all types of buildings. These include old and new builds with and without a cellar, single-family homes and apartments, holiday properties at home and abroad, hotels, schools and offices, halls, garages, factories, civil protection facilities as well as historic buildings, listed buildings, churches, castles, galleries and museums.

The electrical housing of the OMBRELLO® wall drying system (except D7+) covers a wall area the size of an A4 sheet (W 290 x H 220 mm) and has a depth of 140 mm. (See Ombrello)

An entire building, with all its inside and outer walls, can be covered by one OMBRELLO® system. The effective radius is modified to suit the size of the building as well as the degree of damage.

The OMBRELLO® systems are maintenance-free.

The OMBRELLO® systems do not generate any electrosmog and do not emit any radiation, which could be dangerous for humans, animals or plants. (Also refer to the technical functional description in the Downloads section.)

The OMBRELLO® system is completely silent and free from electrosmog.

If the electrical power should fail, the drying process is automatically re-activated and the LED function display lights up green. The OMBRELLO® systems come with lightning protection.

The high-quality electronic components of the system are not exposed to damaging overheating or vibration. The operational life of our OMBRELLO® wall drying system is 30 to 50 years.

Our OMBRELLO® wall drying systems are high-quality Swiss products. We provide a 10-year guarantee for each device.

It is installed in a central position on the floor of the building. Partition walls, doors and floors do not hinder the effect.

Depending on the moisture level in the walls and the building structure, the drying process generally takes 12 to up to 36 months. This time depends on the wall thickness, the moisture levels in the walls and the height to which the moisture has risen. Salt deposits in the walls and the air circulation in the rooms (ventilation) affect the process depending on the time of year. Partition walls, floors and stairs are also dried.

Normally around 18 months.

The drying process can be accelerated by removing old paint, plaster and render, very good room ventilation and drainage of meteoric water.

If the moisture is not caused by capillary moisture (if the moisture does not rise or penetrate from the side).

The smell of mold and mildew disappears after six to twelve months. The walls feel warm and dry. Condensation of the high relative humidity in the room on cold surfaces is eliminated. Mildew and dry rot are banished as the drying process deprives them of the moisture they require.

Before we can assess the moisture of a building, it has to be analyzed. We offer a free, non-binding building analysis service. We would be pleased to arrange an appointment with you. Our specialist inspects your property and on the basis of the analysis we draw up a written offer for drying your property. (Contact)

The non-invasive OMBRELLO® technology does not require any intervention in the building structure and therefore does not produce any noise, dirt or dust. No chemicals are used, and OMBRELLO® is therefore environmentally friendly and does not harm the building’s structure. (See our solution)
