Engineered floor underlay

Evening all,

I have an engineered floor to lay in my house. I was tempted to not bother using a damp proof underlay as I'm sure there's very little moisture left in the slab.

Slab was laid early feb, we had good sun and mild temperatures with little rain before I got the roof on. Also has 2 layers of 1200 gauge DPM polly underneath so will get no rising moisture.

Anyway i've come up with what I think is a true money savers solution. I have some new cotton, polyurethane (albeit thin) backed dust sheets. I suppose I should of left some water it one overnight to see if it leaked thru, but providing they're waterproof sounds like a solution to me. I have some proper foam underlay for on top of this, just not damp proof.

Thoughts???

Thanks.

    Yeh, planning to do tomorrow though, and have no moisture meter. Does my theory re the dust sheets sound right to you?

    Irrespective of whether the concrete is dry or not you should still lay your floor on an underlay with built in DPM. Take the underlay that you have already bought back for an exchange/refund.
