Calling @Desk Jockey (its nice to be needed.. I've heard lol)
Got a below ground bedroom with cinder block walls.
Had water toby above leak which took couples days before it started coming through one of the walls.

That wall was at 6% and rest of walls were 1.5-2% (tramex cmex meter) been drying few days and that wall is sitting at 3%

I know you can take wood to within 4% of dry standard and then let it find equilibrium

But I got no idea on concrete cinder blocks?

Any thoughts/suggestions?

cheers

I think each case will be different even in the same neighborhood. What I would do is look for a dry standard. Other unaffected areas of block in the same home.

If you still aren't dry, I suggest minimizing down your dry chamber. Don't dry that level or room but drop some sheeting and dry only the block.

Heat can really help in cases like that

It has been awhile since I have looked at block, but I believe that is classified as bound water and requires a desiccant dehumidifier, not lgr, to remove.

Energy (heat) will pull it out faster than a desiccant. Desiccants are slow at the size that we buy used for this size job. They use vapor pressure differential to draw the moisture out. It takes time to process the air space to get it super dry for the moisture to jump.

I prefer an LGR and heat to do it fast. We had 65 large Drieaz LGR's and 3 325 cfm desiccants. We only used them a couple of times a year. We would combine the heat from the Phoenix Firebirds and the LGR's to get faster results.
