When laying flooring on concrete, you always need to
have material between the flooring and the concrete to
create an air gap so you don't trap moisture in the concrete
causing mold and mildew problems.
If you're looking for a cost effective solution then I
recommend DRICORE Certiguard.
DRICORE Certiguard's Air Gap technology allows air to flow
underneath your finished floor so moisture isn't trapped.
It also has a few unique benefits compared to other
underlayments sold in the market.
First, it's the only underlayment that has an
overlapping design, which makes it easier to install as you
don't need to take the overlapping seams.
The overlapping design also provides a solid connection
under your floor, eliminating the risk of the underlayment
sheets separating from each other over time, which can
happen with underlayments that are taped together.
The other benefit is the raised design which has higher dimples
compared to other underlayments to provide more airflow and more
protection against moisture or small water leaks.
Dry Core Certiguard has an R value of .9 to help floors feel
warmer and it's very durable product that can support up to
7165 lbs per square foot.
Dry Core Certiguard is the premium underlayment in the
market and it's a great solution for floor protection.
Just remember, when installing any type of underlayment I
always recommend leveling the concrete first to avoid problems
with your finished floor drycore.
Don't build without it.
