Facade Damage
Facade damage frequently occurs in older buildings and can be caused by various factors, including weather exposure, faulty construction, or lack of maintenance. These damages not only affect the appearance of a building but can also lead to significant structural problems that compromise the safety and stability of the building.
Causes of Facade Damage:
-
Weather influences: Rain, snow, frost, and UV radiation can attack facade materials over time, causing cracks, flaking, and efflorescence.
-
Moisture: Penetrating moisture is a main cause of facade damage. Water can enter cracks, freeze, and further damage the material or cause mold growth.
-
Missing or defective sealing: Insufficient sealing at windows, doors, and joints can allow water to penetrate the building structure and damage the facade.
-
Construction errors: Faulty designs such as inadequate expansion joints or incorrect material choices can prevent the facade from adapting to movements or temperature changes, leading to cracks and deformations.
-
Aging and wear: Over time, building materials lose their protective function, leading to facade deterioration.
Types of Facade Damage:
-
Cracks: Often caused by thermal stress, settling movements, or material shrinkage.
-
Flaking: Occurs when moisture penetrates the material and expands during frost, causing layers to detach.
-
Efflorescence: White, salt-containing deposits appearing on the surface, formed when water transports dissolved salts through the masonry.
-
Mold and algae: Moisture in the facade can lead to mold or algae growth, especially in damp or poorly ventilated areas.
Elimination and Prevention of Facade Damage:
-
Regular inspections: Early detection and timely measures are enabled by regular facade checks.
-
Crack repair: Small cracks can be sealed with special fillers or mortar to prevent moisture ingress.
-
Renovation and protective coatings: Flaking and efflorescence can be treated with suitable renovation methods and protective paints to prevent further damage.
-
Improved sealing: Proper sealing of joints, windows, and doors prevents moisture penetration and protects the facade long-term.
