STUDY CONCERNING THE EXCESSIVE HUMIDITY ON THE WALLS OF A RESIDENTIAL BUILDING AND THE HEALTHY IMPACT

摘要

Nowadays many buildings and historical monuments are affected by the phenomenon of capillary ascension of the water through foundation and walls, leading to the appearance of dampness. The presence of excessive humidity in a brick wall leads to the plaster and wall degradation, to an increased heat loss in the affected area and also causes the appearance of mould (bacteria and fungus) on the interior plaster, which leads to a toxic microclimate inside for those who live in the household. This paper represents a study regarding the effects of moisture on the walls of a household and on the human health. It also presents methods which can be used to remove humidity from the walls. Excessive moisture has a negative effect on the indoor climate, leading to the appearance of microorganisms, such as fungi, bacteria, which affect the health of the inhabitants of the building. In areas affected by humidity and where heat losses occur there is a degradation of the materials that the brickwork is made of. House rehabilitation interventions made in the past will be corrected by appropriate measures. Intervention methods will be based mainly on ventilation walls. The materials used will respect the datasheet. The conclusions indicated that the higher levels of humidity were due to poor maintenance of the building, but also to inappropriate interventions, which instead of reducing moisture problems led to their amplification.
