wall drying

Aside from being the quickest method of drying walls, microwave drying is clean, effective, and non-invasive. It is also the least disruptive method for the occupants of the building, and can optionally sterilise biological elements, such as bacteria, mould, mildew, and woodworm.

What is microwave drying:

It is one of the most effective ways for quickly drying a walls as well as floors, ceilings etc. It is used particularly for drying flooded buildings, old buildings, buildings with a very high humidity rate, cellars, flats, as well as for removing mould and mildew from the walls. Water that accumulates in a cellar, which has not been removed over the course of a few days (e.g., flooding - when it cannot be pumped out or removed) causes the capillaries in the wall structure to soak completely. In such a case the humidity rate can be as high as even 22--24% (equivalent to 200-300 litres of water per cubic metre of the wall). It could even take more than twenty months (sometimes whole years) for the wall structure, especially in a cellar, to dry up by itself.

How does it work?

Microwave wall drying is based on the absorption of radiation energy. The molecules of water, fat, and most resins which are placed in a strong electromagnetic field start vibrating. The vibration causes the molecules to rub against one another, producing heat.

In our devices microwaves permeate into the non-conductive materials, such as building materials (brick, concrete, Porotherm, cavity brick etc.), and are dampened slightly as they are distributed within these materials.

The water in a wet wall absorbs the microwave energy very efficiently - several thousand times more efficiently than dry material. As a result, a high frequency field, such as a microwave, causes the molecules of water contained in the material to move and rub against one another. As a result of that rubbing, a large amount of heat is produced, which causes the water contained in the wall to evaporate and disappear from it. That is, the wall drying is not done through the heating of the material, but by the direct impact of microwaves on the water contained in the wall structure. Water evaporation is another effect of heating the surrounding material.

The heating process of the material in an electromagnetic field is affected by the factor of dielectric losses of the heated material (the amount of produced heat is proportional), the thermal capacity of the material, the dielectric material constant (the higher the constant, the greater the concentration of the electromagnetic field within it) as well as the thermal conductivity factor. The value of the dielectric constant of water and its dielectric loss factor is high - is it the reason why it is heated so quickly and evaporates from a wet wall.

To sum up: The microwave generators cause the water contained in the capillaries to be pushed out, towards the wall surface. The entire structure of a wet wall is heated to an optimal temperature so humidity moves towards the external parts of the wall, where it evaporates.

Microwave wall drying advantages

Non-invasiveness - no vents in the wall, no plaster knocked off, quiet and safe.
No noise - microwave devices operate soundlessly.
Disinfection and bloom removal - microwaves destroy all mould and bacteria in the wall structure being dried, so you do not need to apply any other methods (e.g. chemicals). Moreover, microwaves remove the mouldy odour.
Safety - The use of microwave drying does not cause any risk to human health. Residents can stay in the building during wall drying. The walls and ceilings are protected against the impact of microwaves using a special protective mesh. Microwaves are also safe for water pipes, such as HTA, and other materials that are installed in the wall. The device enables very precise control over the microwaves. Thanks to this, undesired effects are kept to a minimum.
Easy and quick use - the microwave devices are small, their weight is less than 30 kg. Extremely easy to use and soundless in operation. Microwaves dry wet and mould-covered surfaces about 10 times faster than traditional methods.
Drying time - depends on the humidity rate and wall thickness. Drying is possible in all seasons and air temperatures.
Cost-saving - compared to other methods (e.g., condensation driers, whose energy consumption is large) microwaves wall drying are very cost-effective.
Efficiency -with microwave technology, drying affects only the wet area while penetrating the thermally non-conductive material. Whereas in traditional methods (where the heat penetrates the material by heating the surface) the air in the room is also heated. This results in a much longer drying process because additional time is needed for the heat to dissipate. You can adjust the efficiency and speed of microwave drying as required. The dried area remains dry forever.

Wall drying

Moisture results
Wet foundations, walls or buildings result in degradation of the walls, freezing of the walls, mould-infection, deformation, reduce the strength of the walls. The water in the material forms separate drops, small amounts in the recesses or capillaries.

Microwave technology
We use microwave technology for wall drying. Microwaves do not heat dry material. They get deep into the wall structure, heating the water contained in it. The steam that is produced increases the material temperature as it escapes outside. Using microwaves it is possible to dry walls, foundations or wooden elements without exceeding 60°C.

Technology advantages
The technology that we use is characterised by several features that distinguish it from other methods:
- drying time is from 5 to 7 times shorter than with other wall drying methods,
- buildings of any size (garages, buildings, halls, churches, offices, flats) can be dried,
- we dry foundations, walls, corridors, open passages, ceilings, church arches, wooden beams, boards etc.,
- material type, its thickness, humidity or salination rate does not matter,
- drying performance is not affected by ambient temperature or ventilation performance,
- does not destroy material structure, painted surfaces, does not damage installation inside the wall.

Mould removal

Organisms such as mould or mildew are likely to appear on wet surfaces causing allergies, producing harmful compounds, lowering the comfort of living and devastating our properties. When other methods fail or cannot be used, we can remove mould and mildew effectively.

Microwave technology
We use microwave technology which enables us to increase the temperature of the infected location to over 80°C. Not only the mould that is visible, the spores and diaspores, but also the mycelium is killed. The building is dried and the mould is removed from it at the same time which makes it harder for mould to re-appear.

The advantages
Washing, scrubbing or scraping living mould and mildew off walls or wooden elements causes the spores and diaspores to spread. They are transported in the air, land on the skin, cloths, furniture, and are inhaled by humans and animals. The technology we use enables us to destroy mould, mildew, spores and diaspores.
- we fight any kind of mould or mildew,
- we do not use strong chemicals, no need to vacate the premises
- the entire wall (brick, plaster, etc.) is dried during the process which reduces the possibility of the reappearance of mould,
- mould, spores, diaspores and mycelium are removed both on the surface and in the cracks and niches,
- the rooms can be used immediately after the process,
- we carry out the services throughout the year, regardless of weather conditions,
- we remove mould from any material or surface,
- it does not matter what the humidity rate of the underlying layers of the wall is or how intensive the mould,
- there is no need to remove plaster or other outer layers.


Insect removal

Insect removal with microwaves

To remove woodworm we use microwaves. Woodworm are killed when the temperature is over 50°C. When the microwaves permeate into the wood it is heated across to 100°C. Adult insects, larvae and eggs are killed as a result of hyperthermia (over-heating).

It is recommended to coat the wood after insect removal. Basic information about wood vermin will help you specify which species you are dealing with.


Technology advantages

No other wall drying technology offers so wide range of possibilities and has so many advantages:
- we do not use chemicals, it is safe for the environment,
- it is non-invasive, does not destroy the material, does not reduce the strength of the wood,
- it is applied on building construction elements and movable equipment, resident relocation is not necessary,
- it eliminates all kinds of vermin, in any development phase, no matter how deep they hide,
- it is applied on every kind of wood including old elements and those with a high humidity rate, it is the fastest way to get rid of vermin where they appear,
- it kills vermin anywhere where other methods are ineffective or costly,
- it can be used throughout the year, regardless of weather conditions.


The wood should be coated even before you begin building a house or erecting a construction. Every cut, drill or processed surface related to the installation should be additionally coated. If it was not done, you should coat everything as soon as possible after erection.


We offer conservation and impregnation of the wood used for building a house, wooden constructions, terraces and external elements. We coat the wood in residential houses, public buildings, industrial facilities, farms, historic buildings. We protect the wood against fungi, moulds, vermin, fire, weather conditions, UV.

External constructions

We protect elements such as gables, walls, soffit boards, gazebos, mezzazins, fences, etc., against the impact of weather conditions and biological hazards. The coating we use not only protects and secures, but also improves its appearance. Depending on requirements it can increase the visibility of the natural properties of the wood or change its colour.

Construction timber

We protect internal constructions, such as rafters, roof beam, patches, beams against fungi, mould, wood vermin and fire. We use a brush or hydrodynamic generator to apply the coating. It is non-toxic and odourless so there is no need to air the rooms after application. We protect ornamental elements, such as ceiling beams, with varnish coating which protects also against vermin. It retains the wood's characteristics via a selection of colouring agents. It can be used in closed rooms.

Terraces, stairs, landings

The only effective method for coating is through oiling. Coating for local or exotic wood types with addition of natural components make it look as matt as silk and resistant to dirt. An additional layer protects against UV.
