Basement and Crawl Space Dehumidifier

During humid weather if you have some puddling on the basement floor or dampness, and it is not caused from water infiltration through cracks, rising water tables, or pipe sweating, it is a humidity problem. Just because you have a basement waterproofing system or crawl space waterproofing system doesn't mean your basement or crawl space is moisture free. It's not dry - unless it feels dry, smells dry and looks dry.

Is your basement damp? Often water enters a basement through capillary action, which wicks moisture through walls and floors. The floor and walls may not leak, but it feels damp to the touch because it is wicking the water inside it to the surface. Water vapor is also a problem, slowly seeping through concrete and raising the humidity.

If the outside air is warmer than the air in your basement, particularly when it's humid outside, condensation will become a problem. Because houses work like chimneys - they suck in air at the bottom and expel it at the top - your basement may be more humid than ever in the summertime. This is because the Relative Humidity of air goes up 2.2% for every degree you cool it. If it's 87 degrees outside with a Relative Humidity of 82%, and we pull that air into our 68 degree basement, the Relative Humidity goes up by 41.8% (19 degrees x 2.2%).

Since the total is greater than 100%, all the excess humidity is deposited as condensation on your cool basement floor, walls, pipes, water tank and other cold things. Even without condensation basements tend to have high humidity levels and mold grows rapidly, generating that musty basement odor. Dust mites love that high humidity too.

There are only two possible ways to eliminate condensation: heat the air or pull the moisture out of it. Obviously heating your basement to match the outside temperature is counterproductive, so the only real option is to dehumidify.
