[30] The "tide mark" is commonly distinguished as a feature of rising damp.
[2] A vapor retarder and an air barrier serve to reduce this problem, but are not necessarily interchangeable. Vapor retarders slow the rate of vapor diffusion into the thermal envelope of a structure. Other wetting mechanisms, such as wind-borne rain, capillary wicking of ground moisture, air transport (infiltration), are equally important.
Waterproofing with two component system. In buildings using earth sheltering, too much humidity can be a potential problem, so waterproofing is critical.
