A qualified surveyor would usually isušivanje vlage have the capacity to pinpoint the reason for damp, for instance a leaking gutter leading to rainwater to cascade and saturate the exterior structural wall which in turn leads to rainwater to ingress internally and adversely have an effect on The interior building material.[13]

Injection of a liquid or cream into bricks or mortar is the commonest means of managing rising damp.

Despite the fact that reasonably minimal interest has been directed to dampness and mold progress in heating, ventilating, and air-conditioning (HVAC) units, There is certainly evidence of linked health and fitness effects. Pollutant emissions connected to humidity and microbial expansion in HVAC devices are considered one of quite a few opportunity explanations for your regular Affiliation of air-conditioning systems with an increased prevalence of nonspecific overall health signs or symptoms, called sick building syndrome, knowledgeable by Office environment workers (Seppänen and Fisk, 2002).

Each time a building is air-conditioned, the vapor-strain gradient is from the exterior toward the inside, wherever condensation around the back again side on the intentional vapor retarder may arise. The situation is aggravated In case the building's cladding is made up of a cloth, including brick or break up-confront block veneer, that absorbs rainwater, as the vapor-stress driving pressure is significantly greater when the Solar raises the temperature from the veneer to that of liquid h2o.
