Salt Contamination & Desalination in Heritage Buildings

Heritage buildings are susceptible to deterioration due to several factors including climatic conditions, dampness and structural failures. In building conservation, salt attack and rising damp are considered the most challenging.

Salt attack and rising damp are closely related. Moisture from rising damp can dissolve the existing salts in the building material; in addition, ground water that may sometimes contain salt can find its way through the building walls. The Moisture then evaporates on or just below the surface of the wall, leaving salt residue and deposits behind. These salts build up in the plaster and on brick surfaces over a period of time and attract airborne moisture. the expansion and contraction of such salts that causes the familiar rising damp symptoms of eroding and blistering paint and plaster. This significantly affects the building’s aesthetic value.
