Looking for a term to use to describe flowering minerals on what appears to be a dry surface.
Wicking is the only narrative I could come up with.
My hypothesis: hydraulic action leading to flowering mineral staining, efflorescence.
Recently Remodeled home. >< 18 months.
It appears the home was completely gutted and the first level wall layout changed.
What was original, footing, foundation, some of the structure.
It appears the lot was not sloped to municipal standards.
The image is from the utility room slab.
The area of efflorescence extends from the sump basin, located at the rear of the property, towards the front of the home and is roughly >3' feet long..
Size of staining: Roughly 2.5' wide starting at the basin, >< 12" at the furthest point >< 3' feet away.
Note the flower minerals on the new 2" x 4" inch concealing the subfloor joists.
The flowering minerals are on the concrete as well as forming on the 2" x 4" inch wood object.
The wood object is visually stainless from moisture YET the flowering of minerals continues off the concrete flooring to the wood joist.
I decided not to utilize my moisture meter/s as ot to compromise the small sampling of flowering minerals on the wood.
I repeat, there are/where no visual clues on the wood moisture was/is being wicked thought the wood. I would at least expect to see saturation and atmospheric grim stains.
As well, the utility room was under negative pressure. The door would close if left 12" inches open. you could feel the draft entering the utility room. I should have used my smoke pencil and taken pictures to use as evidence for my HVAC reporting narrative.
I also hypothesized that negative pressure in the mechanical room is mechanically drawing any bulk water moisture in contact with the slab in the room but did not put this in the report.
