What is capillary rising humidity?

Capillary rising humidity is a continuous and constant flow of water molecules that rise from the ground towards the top of the walls at various heights. By saturating the upper external parts of the plasters, the humidity in contact with the air begins to evaporate and disperse into the environment. Biodry is the only technological device that eliminates the problempermanently!
