Can anyone guess this one out?

[icleancarpetz]

i sure can’t. Scratching my dome as to how this bedroom got a parking lot look with filtration soil. Empty house this morning. New owners just bought house and dont know either.

Moisture from underneath in the crawlspace?

 

[hogjowl]

Nobody cares
Just clean it

 

[Lee Stockwell]

Negative air, from a furnace RETURN line between the floor beams pulled unfiltered air thru gaps in the plywood floor, leaving filtration line in the middle of the floor

 

[Lee Stockwell]

I care, because it will come back, until that is fixed.

We all understand how it happens
His question is more directed at the unusual pattern

Pattern of the single layer of plywood..

Pattern of the single layer of plywood..

Or thicker carpet pad vs worn padding?

 

[Dolly Llama]

what's under the room?
Main floor?
Basement?
Slab?
and how old is the house?
and was that the only room like it?

we don't know what the previous folks had/did there .
hell, for all we know, it's tape residue from a checkerboard hopscotch game .
Or it's used rug that was folded wrong and sat for years in a dirty/disty place

The the first pic though, sure looks likes the pattern a subfloor would be laid


..L.T.A.

 

[Sierra Clean Care]

Filtration lines through subfloor just as Lee pointed out.... if you look at the size of the pattern, it’s 4’ by 8’.... exactly the size of a sheet of plywood...

Amazing conclusion! Learned something new.
that was worth the price of admission here.

Will contact the new homeowners and let them know i had a sample taken to my “lab analysis expert” and this is results of their findings.

Grab a corner pull it back see if that's where the seams in the plywood are. Lee wins....

Did you re stretch that carpet when you put it back?

 

[Lee Stockwell]

Yes, usually with a kicker, unless a power stretcher or open seam needed closed.
