basement waterproofing

The most important requirement for a long use of buildings is a dry foundation masonry. Moisture penetrates through the basement, which affects the entire construction, and much worse, on the health of the residents. The result of rising damp from the basement are: mold, stains and peeling plaster - the deterioration of the building fabric is unstoppable.
Not only does the moisture from the basement reach the masonry but also the roof, but also the fact that many cellars are used as living, working or hobby rooms in the private sector makes extensive cellar sealing necessary.
In a new construction, this is less of a problem, because as the rising damp is known, the same measures are taken in a new construction, with which an ascending moisture can be avoided.
The basement seal is more difficult in existing buildings. It is often associated with a very high work and cost.
Causes and their solutions
Before a basement seal can be made, the cause of the onset of moisture must first be defined. Only when the cause is resolved can a basement seal be successful in the long run.
A bituminous undercoat and a bitumen thick coating have been established for the cellar seal. In this case, a vertical seal against damage must be protected by what is done by thermal insulation boards or Kunststoffnoppenbahnen. this is a
Measure for basement sealing, which takes place from the inside.
If the basement rooms are to be used as living space, an insulation and sealing from the outside is also required. If moisture penetrates from below, ie above the floor slab, a seal must be installed at this point about ten centimeters above the basement floor and approx. 30 cm above the ground level. So can in the future
no more moisture.
However, if the moisture from the sides in the masonry, this v must be protected by appropriate measures against moisture. One of these measures is the injection procedure, in which a number of holes with a diameter of up to ten centimeters are drilled in a specific arrangement. Subsequently, the holes are filled with a special injection liquid.
Due to the special arrangement of the holes results in a barrier and moisture can no longer penetrate. Alternatively, there is also the so-called Mäersägeverfahren or steel sheet method.
When Mäersägeverfahren the bottom wall joint is sawn and installed in this a moisture barrier in the form of a stainless steel plate. In the steel sheet process, steel sheets are hammered into the masonry.
Both methods are very time consuming and extremely labor intensive. In addition, this involves very high costs and, if carried out incorrectly, cracks in the masonry can occur, which negatively affect the statics of the entire building.
Planning and consulting by a specialist
Careful consultation and planning is essential for proper foundation protection and should be carried out by a specialist. Corresponding specialist companies for the basement waterproofing can be easily found on the Internet. The search engines offer a great help here.
Especially in existing buildings, a professional masonry seal in the basement is important. Building materials such as bricks, mortar and concrete are porous and absorb moisture from the soil. For this reason, it is imperative to seal earth-contacting basement walls against the action of water.
As mentioned several times, a basement seal is sometimes associated with very high costs. On average, you have to expect about 300 euros per square meter. Therefore, it is always recommended to have several offers created by the respective specialist companies and to compare them with each other.
