Rising damp is water from the soil that gradually moves upward through microcapillaries of the construction material into walls.
Usually it reaches the height of 2 meters carrying dissolved salts, whose crystals cause severe damage. The construction materials start to inflate, peel off in sheets, fall apart and eventually separate from the surface.
Dampness does not affect only the object but also the health of persons who reside in it.
Objects without waterproofing
All objects without waterproofing have problems with rising damp.
Older objects
Older objects are built directly on the ground, without waterproofing materials.
Newer objects
Rising damp can exist in newer objects with waterproofing which are damaged due to wear or other reason
Rising damp is a known characteristic of older houses, buildings, castles, religious structures/buildings and similar.
Damp walls contribute to growth of fungi and mould whose organic debris saturates the air and causes various diseases, sleep disorder, weakening of the immune system, allergies, asthma etc.
