At the origin of the humidity present inside homes, saltpeter remains harmful to humans and their environment. It can cause various diseases as well as the destruction of the foundations of a house. Because of these different reasons, we must immediately proceed to their elimination as soon as the first signs appear. However, only an expert will know how to go about overcoming this pest.
Saltpeter: what is it?
Saltpeter is a mixture of various nitrates that form on old walls and barns. Whitish in color, this phenomenon also called stone salt is quite common in old houses. In order to identify it, traces of white powder are observed on the walls of the dwellings. This is the cause of the humidity that occurs inside homes. Indeed, saltpeter has the ability to absorb water that is in the air. Subsequently, he brings it back to the walls of the houses, which ends up causing significant damage.
Following a rise in water by capillarity, we notice a development of this phenomenon on walls with little water resistance. It is for this reason that cities with concrete constructions do not usually encounter this kind of problem. The same applies to urbanised areas. On the other hand, a wall can be in contact with the land as in the countryside. In this case, it is normal to face a foundation crack.
In addition, places not far from swamps or marshes are more likely to suffer from this phenomenon of saltpeter. In the same way, following a wall drying operation, this event often appears.
The risks associated with the presence of saltpeter on the outer walls
Regardless of the materials that were used to build a house, one must remain cautious. If the walls are attacked by stone salt, it remains dangerous for its occupants. Let us remember that this chemical compound is hygroscopic. Therefore, to think that our walls always remain watertight would be a misconception. It is therefore essential to ensure the humidity level within the walls of our homes. The presence of potassium nitrate on our walls can cause respiratory disorders such as asthma.
From the moment white traces, salt deposits or halos appear on a wall, caution is required. This means that saltpeter is present on the walls of this house. It is the same, when the paint inside peels off. An external crack can occur as a result and cause a collapse of the house. If wood or stone was used as a support for your walls, stone salt can turn them into rot. It is therefore essential to take measures to remedy this dangerous phenomenon.
