I have an older home (80+years) and I have an unfinished basement.
The drainage around the foundation is not very good which means I get a high level of moisture in the basement.
The floor slab was simply poured on top of clay so there is no drainage under the floor.

in the peak wet months I get extreme moisture on the floor. it's not really a puddle. I get a lot of wet spots on the floor.

I only use the basement to store my bikes and I have a small little spot where I keep my tools and of course the washer/ dryer are down there as well.

my question is the following:

I've been thinking about putting a DELTA (OSB with a dimpled plastic sub base) sub floor just so I wouldn't walk on the damp cement.
do I run the risk of making things worst in the basement by putting down this floor (in terms of the humidity)??

or will whatever humidity that was there before simply run under the floor and find it's out on the side?

Reason I'm using this product is because I can get it at cheap price from a friend. (entire basement will cost 600$ CDN) and it only takes away 7/8 of an inch from my headroom.. since it's an older home, it doesn't have much room to start.

thanks for any advice on this

The ONLY way to deal with basement water/moisture problems as severe as yours is to treat your basement as a whole.
