Shoutout to the crew that shared a moisture check method for concrete slabs

In my area, I've noticed a shift towards slab foundations in new builds. This change means we're dealing with more moisture issues under floors. A veteran crew showed me a cheap trick using plastic sheeting and tape. You lay it down, seal the edges, and check for wetness after 24 hours. I used this on a recent luxury vinyl install and caught a problem early. Now I make it a standard part of my prep work. It's saved me from several potential failures.

Man, I should have used that trick before my own garage floor disaster. I felt so smart using that fancy moisture meter the store sold me, but the plastic sheet would have shown the real story way cheaper. My pride cost me a whole weekend redoing that floor. Now I keep a roll of plastic in the truck like it's part of the tool kit.

Your plastic sheeting trick is GENIUS. My friend learned the hard way when he ignored a moisture check on a garage conversion. The adhesive failed after two months, peeling up all the luxury plank. He lost money and a client. Now he uses that exact method before every single install.

Turns out plastic wrap is smarter than some contractors. That's a really expensive way to learn a basic step.
