Rising damp is essentially due to a physical phenomenon of vehiculation, ie the water’s ability to penetrate the walls and to rise from the ground upwards through the capillaries present in the materials constituting them; the water goes back to the capillaries, until the forces involved find equilibrium.
The phenomenon of ascent by capillarity manifests itself every time a liquid comes into contact with a small vessel called a capillary.
The water is then disposed of through the normal process of evaporation through the surface of the masonry, triggering a process of degradation of the elements that constitute it, causing the following damage:
– Widespread presence of stains and salt efflorescence
– Detachments of the plaster from the masonry
