What is important is the correct sealing, so that moisture and humidity not penetrate into the masonry, as threaten otherwise mold and moisture in the basement. There are shafts of light from a variety of materials, such as concrete, from a precast concrete manufacture, already cast or plastic. What is important is the correct sealing, so that moisture and humidity not penetrate into the masonry, as threaten otherwise mold and moisture in the basement. Waist precast often lack fixtures. Lacking but also already in the larger planning connection accessories. So is not suitable or little accessories resorted to and gaps, which can allow the moisture. The sealing of the building is important above all where it meets the Earth.
Afterwards the finished light shaft to the so sealed off part of the building should be, attached as the joint between building and light shaft no longer necessarily sealed needs to be. Of course, this joint can also be sealed, however, this is not a condition for the tightness of the light shafts on the buildings. When fixing with screws material is sure that across is carefully smoothed to the fittings. Mainly water and also subtly occurring moisture must be kept away from the waist. So, the light shaft floor is sufficient to drain, and depending on the size of the light shaft, the water absorption capacity of the subsoil and the quantity of water to be expected. This drains are usually created. A drainage should ensure that no moisture in the light shaft can collect. This will prevent that adverse effects on the light shaft arising through a water accumulation and consequent waterlogging.
Of course, all this is only useful if the basement Windows are also protected from moisture. While the cellar wall is constructed, they are integrated directly with. Sometimes it is also necessary to add a lintel above the edge of the window. The materials, which basement are made, are particularly metal, wood or plastic. Typically, they have a simple glazing and sometimes one that protects against invading heat. It should be by no means avoided a lighting well cover from above and a grill outside the window, so that can get mice or similar small animals not in the cellar. Coarse dirt held it as effectively. Of course, the lighting well cover carries several tasks. Therefore, it is important to choose the right lighting well cover. Only a light cover in high quality, from the finest materials, and perfectly processed to fulfill all responsibilities. Only when these things are guaranteed, it seems reasonable to worry about sealing the light shaft, because what does not use a light shaft, which meets all requirements for protection, the existing basement window but just. Water could penetrate so still and the protective function of the light shaft as obsolete appear. Another issue for basement is the protection against burglary. Therefore, the light shaft must be secured against accidental removal from below. For this purpose there are special fuses for light manhole. These backups are available from stockists. You prevent that a burglar or someone else fraudulently opened the light shaft. Light wells can be still afterwards sealed and secured. It’s never too late to provide the security. All this is also taken into account, in what area, the building is and the question whether it is a region, is the flood threatened or not.
