“For reference, whenever we moved in- floor was relatively level (LVP had just been installed) But now, a portion of the flooring appears to be raising up (subfloor included).”source ↗
“One of the female grooves has failed and it's in the middle of the kitchen. It flexes when walked on and has caused the neighboring plank to start failing. Removing and replacing is a lot more work than I'm willing to tackle. I am wondering if there's any product I could drill a hole and inject to stabilize.”source ↗
