In addition to damaging the appearance of the house, infiltration can affect the health of the inhabitants and decrease the value of the property.
Main causes of wall infiltration
1. Hidden leaks
Damaged pipes inside the wall can allow water to spread slowly through the masonry.
2. Lack of waterproofing
Properties without adequate waterproofing are more vulnerable to moisture from the soil, rain, and humid areas.
3. Rain
Facades with cracks or cracks allow rainwater to enter.
4. Roof problems
Broken tiles, clogged gutters, and failures in the coverage can cause internal infiltrations.
5. Rising damp
The water from the soil rises through the walls by capillarity, causing stains near the floor.

Frequently Asked Questions about Wall Infiltration

Generally, infiltrations caused by rain appear or worsen after rainy periods. Leaks, on the other hand, usually cause constant stains, regardless of the weather. A professional inspection can identify the exact origin.
Can wall infiltration cause health problems?
Yes. Moisture favors the appearance of mold and fungi, which can trigger allergies, respiratory irritations, and worsen diseases like asthma and rhinitis.
Is it possible to paint a wall with infiltration?
It is not recommended. Painting can temporarily hide the problem, but moisture will continue to damage the wall. It is best to eliminate the cause of the infiltration before painting.
How much does it cost to recover a wall infiltration?
The cost varies depending on the cause of the problem, the affected area, and the type of repair needed. Small repairs are usually cheaper, while structural problems may require a larger intervention.
