Robert, really? to do a thorough assessment one needs a moisture meter and hygrometer?
Hmm, that’s strange, in 41 years doing thorough assessments i have never needed nor used either, and neither has Capizzo or Stremersch or a couple others i know who are waterproofing experts, but again i guess i am wrong and Robert n others are right… right? lol
Lansing MI, very nice lady homeowner had several INT system chumps over all wanted a ton of $$$ to install an INT drainage system which would NOT have stopped the water from where it was first entering, through exterior cracks n other ext openings in, and just above her front wall and front porch, MOISTURE METER etc would not have done ssssssssssssssquat to identify her actual problems and only solution to STOP the water, sheesh… photo is of the inside of where her front PORCH is outside
yeah there were also EXT cracks in wall and openings above porch around door
went to LANSING from SCS, back then cost was $3,300, would not do it again for that amount VERSUS what the INT scumbags wanted to divert the water on the inside one wanted $8,500 for a partial INT system, all others were $12,000 and up and that was many years ago
After looking at all these horrible basement pics I feel blessed I’m in South Florida & do not have to inspect & deal with this stuff.
Only twice in my career some dope tried to go “down” under the slab & guess what I found… … … … … … .
I had two contractors come out and give me an estimate: Estimate one: 1) Install outside drain, 148 LF, $44,458, at footer. 2) Interior drain, 148 LF, $10,360, and 3) Multistep, Interior and Exterior (drain not at footer but halfway from footer to grade), $24,660 and this is what they recommended.
Estimate two: Interior drain for $5,900 (80 LF, not the whole perimeter of the basement,only for the water intrusion areas.
My thoughts exactly as well when I saw those pics. Might want have the material tested and be sure to wear masks if working on the floor, also, many of the adhesives that they glued the tiles down with contained asbestos.
As for the water damage the OP is referring to, call what you see and you’ve done your job, I would also be on the lookout for “any organic substances consistent with mold” and report those findings as well.
I am sure it is ACM or VAT, because I recognized the pattern. My Father used to do a lot of Store Building Malls in the 60’s and I was there to help him install those tiles with the old black cut-back adhesives. You could put down that adhesive at night and install the tile the next morning when you could walk on it. Snap your lines and go. Only way to know though, is to have it tested.
