I live in the Denver area... heavy clay soil.
My basement is partially finished. I have a wood floor that is about 3 feet off the dirt underneath. There is a french drain around the perimiter with a sump pump that seems to work overtime, but it keeps the sump clear and is working fine. Under the flooring there is a fresh air intake and an exaust fan that runs various times thru the day.
With all that my basement still smells very musty, will installing a vent with a fan to circulate air help?

HI bwright,

As long as the dirt underneath isn't 'sealed' off with, say, 6 mill thick plastic, moisture is going to constantly permeate upwards. And by circulating the air under there, you're only compounding the problem.

You can try a dehumidifier to see if it works hard enough to dry out the surface of the dirt. If that doesn't do the job, you need to put down some poly.

Unless I'm missing something, that's it. My best to ya and hope this helps.

Thanks Jay,

Interestingly enough, when the house was built 3 years ago, they put black poly in the crawl space under part of the house, but under the basement, they did not.
The fresh air intake and exaust fan pull air over the dirt under the floor to rid the house of radon... a CO problem. The dirt seems dry, but I understand how it can still radiate moisture.

I'll give the poly a try.
