Water droplets through LVP in basement

Question

About two years ago I placed LifeProof LVP in the basement on the concrete floor. Today, after about two days of rain, I noticed some droplets between some of the seems in the room with the LVP. Not everywhere mostly in one small area and its just some droplets, not a lot of water.

A few questions:

1. Should I have put an underlayment down for moisture? LifeProof says that their LVP has underlayment, so I didn't but now I'm thinking I should've put Dricore down beforehand.
2. Should I rip out all the existing flooring and replace with underlayment + new flooring? Or since this flooring is "waterproof" can I just keep it as is?

Thanks for the help

Flooring guy here.

Answer; Your flooring is okay. The subfloor should be able to handle some drops of water. If there's a LOT (like a gallon plus, or a constant, leaky pipe) of water, it's probably worth checking the subfloor for water damage.

LVP is a waterproof product, as in, it's fine if it gets wet. But most LVPs don't have watertight joints and won't prevent water from going through like sheet vinyl or linoleum would. There's a lot of newer laminates like Mohawk Revwood, Engineered Timberstep and some others that have watertight locking systems. You have to caulk the perimeters but they do keep the water from going through to the subfloor like you're running into.
