A few ways water travels
Have you ever wondered how water moves through a structure? Listed below are the definitions of the different ways water moves through a structure.
- Bulk water movement- Typically thought of as rain or snow; bulk moisture movement also includes flowing groundwater.
- Capillary action (capillarity)- is the ability of water to travel up against the pull of gravity through a porous material.
- Air transported moisture- water in the form of water vapor hitchhiking on air can leak into, or out of, buildings.
- Vapor diffusion- Even without leaks, small amounts of moisture in the form of water vapor can pass directly through a building’s envelope, through a process called diffusion.
These different ways water can travel through a building may seem minuscule, but over extended amounts of time can cause serious damage. In some cases the moisture can turn into mold, making it a very different but severe problem.
