Rising moisture indoors |
Rising moisture can be defined as water rising up from the ground, through the moisture-permeable structure of a wall. The water rises up through the pores (capillaries) of the masonry, under the influence of a process called ‘capillarity’ . In other words, the wall acts as a sponge. All this takes place above ground level.
Groundwater contains small amounts of soluble salts. These are dissolved and transported along in the groundwater and remain behind when the water evaporates. This implies that, even if the rising moisture is kept in check by means of a moisture-proof coating, these salts can cause the wall and any salt-affected finishing coats to remain moist.
That is why AQUALITY PROTECT recommends to consider two factors when a dry wall AND a dry finishable wall surface is desired:
- The application of a moisture-proof coating, by means of ‘dry injection’, with a warranty of no less than 30 years.
- The removal of any decorative and plaster coats affected by salts, replacing them with appropriate plastering in order to block the passage of moisture or any hygroscopic salts left behind in the masonry.
