It is the floor’s core that gives it waterproofing and stability. (The wear layer’s job is to increase durability.) Thickness matters. You can find cores usually in the range of 2.0 to 4.0 mils. Instead of the traditional core of vinyl composites that are typical with luxury vinyl, this one comes with a WPC (wood plastic composite) core that will not peel or ripple no matter how much or for how long it’s exposed to water.
WPC also makes the vinyl even thicker, which enhances stability and gives it a more rigid feeling. That rigid core means it hides subfloor imperfections. Uneven floors or cracks will not telegraph through to the surface floor.
There is another alternative: SPC (which stands for solid polymer core). It, too, is waterproof but even more firm with greater stability. Vinyl also tends to expand or shrink to adjust to the weather. This core doesn't let it move at all.
