What is sagging moisture?

Intrusion
Permeable damp refers to moisture that enters through the outside of a building and seeps through interior walls.

Precipitation
Precipitation, such as rain or snow, hits the outer walls of a house, so to speak.

Absorption of moisture
These exterior walls then suck in the moisture and absorb it. This gives precipitation a chance to soak into the walls.
What causes persistent damp?
Under normal circumstances, a wall should not absorb moisture. Nevertheless, there are some common causes of penetrating damp:
Typically, older homes or those with flat roofs are more likely to have this moisture problem, due to, for example, plant growth against the outer walls or weather conditions that weaken the outer walls over time. But, a construction fault or leaking gutter can just as easily cause water to seep in over time.
What are possible consequences of persistent damp?
Moisture problems as leaking moisture are usually accompanied by negative consequences.
Damage to your home
Penetrating damp can cause a lot of damage to your home. Wallpaper and plaster can come off the wall, with fungi can occur which also does your furniture no good. Thereby, it not only damages your interior walls, it also affects your exterior walls.
Health complaints
Moisture in the home and mould is further associated with low air quality and a bad odour in your home, which for health complaints can cause. Airborne mould spores and bacteria increase the risk of allergies, asthma and respiratory infections. Moreover, a humid environment attracts house dust mites, which can cause additional symptoms in people with respiratory problems or allergies.
Structural problems
In addition, penetrating moisture can seriously weaken a home's structure. In the long run, walls and foundations can crack or sag. Moreover, moisture can cause metal components such as nails and pipes to rust, further compromising the stability of the structure.
Higher energy consumption
Are your walls insulated? If so, the insulation material can also get damp, losing its insulation value. In addition, your house will also feel cold, so you will heat more and feel this in your wallet.
It is therefore more than advisable to combat persistent damp in time to limit further damage.
How do you recognise leaking damp?
Permeable damp can be easily recognised by the random places where the damp problems appear. Unlike rising damp, which occurs on the ground floor and in basements, penetrating damp can also occur on higher floors. You can usually recognise it by the following:
Exterior of the house
Interior of the house

Fighting persistent damp for good
Facade impregnation (including hydrofuge) is the most effective method of combating penetrating damp by applying a transparent, waterproof layer to the façade, preventing rainwater from entering. This treatment offers benefits such as extra insulation, a durable solution, quick implementation and possible government support in the form of premiums.
The process starts with a thorough inspection of the façade to ensure adhesion, followed by any minor repairs. The impregnating agent is then applied to the façade using a sprayer.
