Measuring moisture coming thru basement slab
My 2150 SFT ranch home with ICF walls and a full basement has NO vapor barrier (polyethylene layer) under the slab. Just pea gravel surrounded by drain pipes that exhaust into a lake behind the home. Currently I am running a stand-alone dehumidifier continuously and this is keeping the basement at about 35-40% RH. I also have a radon SSD fan installed a few weeks back. The fan is a RadonAway RP140 that uses 14W and is energy star rated.
I am wondering if there's a way to tell how much moisture is coming in thru the basement slab. Based on the measurement, I would like to test and see if a more powerful radon fan will help extricate more moisture thru the radon pipe so I could potentially do without the dehumidifier in the basement.
While we are on this subject, I read elsewhere moisture travels upward; I would appreciate correction on this point, if needed.
Thanks in advance.
