Does basement floor need moisture barrier?
For a dry, mold-free finished basement floor, always install a vapor barrier before laying a wood subfloor or carpet pad.

What is the best moisture barrier for concrete floor?

What type of flooring is best for basements?
The best type of flooring for basements is vinyl. Vinyl flooring can come in the form of vinyl plank and vinyl tile, giving it the ability to look nearly identical to hardwood and stone products with the added benefit of being waterproof. Vinyl flooring is made of PVC making it durable and waterproof.
Do you need a moisture barrier under concrete?
Water vapor will always move from a high relative humidity environment below the building into an area of low relative humidity – even through concrete. That’s why nearly every expert in the concrete industry recommends a below-slab vapor barrier to stop the vapor drive of water upward and into your building envelope.
Can moisture come up through concrete?
Concrete’s porous nature means that water from under your home can seep up through your concrete floor, making it damp. Basements and garages – the typical rooms with concrete floors – also suffer from poor air circulation, giving the moisture nowhere to go once it seeps through the floor.

Should I use a vapor barrier in basement?
Building codes usually require a vapor barrier (4 mil plastic sheeting) on exterior basement walls if the framing is attached to masonry or concrete surfaces, or if the wood framing butts up against the outer basement walls. You should then use fiberglass insulation that has a vapor barrier between the studs, with the vapor barrier facing in toward the living space.
What moisture barrier should you use under laminate flooring?
A vapor barrier under laminate floor, required for most laminate flooring installed over concrete.
