Tropfeninfiltration

Tropfeninfiltration refers to the process by which water penetrates into a porous material through small openings, often in a slow and steady manner. This phenomenon is commonly observed in construction and civil engineering, particularly in relation to building envelopes and foundations. When water, such as rain or groundwater, encounters a surface with small cracks, pores, or joints, it can gradually seep through these pathways. The rate of infiltration depends on several factors, including the size and connectivity of the pores, the surface tension of the water, and the pressure difference across the material.

In buildings, tropfeninfiltration can lead to various problems. It can cause dampness within walls, which in turn can foster the growth of mold and mildew, compromising indoor air quality and potentially damaging structural components. In basements and foundations, it can contribute to water accumulation, leading to hydrostatic pressure and potential structural weakening. Understanding tropfeninfiltration is crucial for designing effective waterproofing systems and for diagnosing and repairing existing water ingress issues. Preventive measures often involve sealing cracks and joints, applying water-repellent coatings, and ensuring proper drainage around structures.
