Basemant Moisture on flooring

Dannun66

We found our 20 year old home w/ finished basement had some minor mold issues. We removed the old drywall from the outer cinder block wall and sealed the cinder block and floor with drylock. Insulated walls with rigid foam sealed and vapor barrier. Placed with Mold resistant drywal, trated furring and vinyl flooring.

No we are getting moisture on top of the vinyl. We live in Fairbanks Alaska and it is cold. Heating is forced air and the water is showing up in one room in the corner of the house basement on the floor.

Is this a humidity issue from condensation? Should I redo the heating system and place radiant floor heating with an HRV or should I do a subfloor?

Thanks
Steve

Why don't you just put in a dehumidifier?

Well I needed to solve the mold issue. Since my post I have done further research and discovered I created another bad environment for more water to shed off the cold cinder blocks onto the floor.

It needs to be fixed now or it will eventually mold and water will continue to form in the cavity between my rigid foam, and my second vapor barrier and literally drain onto the floor.

I wish I could solve it with just a humidifier but I think there is way to much water shedding from behind the wall.

Thanks for advice

You'll never solve a mold problem in a basement with that heavy of a water infiltration, especially if you keep giving the mold a food source. (The drywall, etc.)

Another possibility: Look into the chance of a draft of some-kind coming into that area of the foundation/floor.

Cold air meets hot air and you get condensation...

may be a leak is not possible in such a cold weather as everything is ice... but if this is a leak from outside wall... the only solution is to fix the leak...
