Greetings All
I recently had a flooded basement. The strapping, vapor barrier and 5/8 T&G all had to be removed. I’m thinking of 1″ EPS foam sealed and taped . Here’s where my questions start.
1. Can I apply an engineered wood floor over the EPS?
2. If you think I need a layer of wood between the EPS and the flooring, Can I use T&G OSB instead of T&G plywood?
3. Has anyone had any experience with a 3 in 1 underlay for laminate floors over concrete?

"1. Can I apply an engineered wood floor over the EPS?"
Well you can't used a nail down install. And I think that a glue down would not work unless you can get a 100% coverage and the adhesive is compatabile with the EPS.
And I would be concerned with the snap and lock type of install. I don't know how flexable it is after it is locked together. The one thing that you don't want is for the floor to flex and have any place that concentrated the load. If you get conceptracted point loads the EPS and breakdown at those points.
A glue togehter floating floor should work.
"2. If you think I need a layer of wood between the EPS and the flooring, Can I use T&G OSB instead of T&G plywood?"
If you use 2 layers glued and screwed togehter you don't even need T&G. Don't know any reason that it can't be either osb or ply.

VAS IS DAS?

Pretty flexible. Probably get a good wave over anything with even a little give.
3in1 is a moisture barrier, foam layer and has a sound deadening component
2in1 just has the moisture and foam.

There was an article related to that in FHB not 'too' long aga............maybe someone else can come up with it.
Maybe Andy Engels basement article?

I don't know - never done it nor seen it done...
quick note though: Rigid foam is available in different compressive strengths. Something to consider when selecting a foam product...

If you use foam I would use XPS, not EPS on the floor.
Also check out this FHB article (which uses EPS on the floor). XPS is better in this application, particularly for what you are trying to do:

I didn't see it in your opening message but I assume that you have addressed WHY the basement flooded in the first place. Otherwise, this discussion is a bit premature.
I had a plastic fitting on a water filter crack and flood part of our basement, which was half finished. I had done the finished part using Delta-FL which provides an airgap between the slab and the floor. Above the Delta-FL I used one of those 'recycled textile with plastic on the bottom pads' and a snap-click laminate floor on top of that.
Anyway, the water didn't get deep enough to get up to the real floor level, and with the Delta-FL and lots of fans it dried out nicely, not ruining the floor.
I don't have floor drains in the basement. That would have been very helpful!
This is all to say, "expect the basement to flood sometime," and plan accordingly. Perhaps I should have done insulation over the Delta-FL, but I didn't.
Thanks for the comments, I have solved the water problem. Someone decided to seal around the well pipe with fiberglass insulation and gobs of silicone, and than hide it with fiberglass insulation and vapour barrier. I have removed everythingand used hydraulic cement to fill the gaps. I will then dig it up on the outside and seal it properly.
I may try the 3-in-1 underlay under laminate, my brother recently had it installed and likes the results.
Hydraulic cement is definitely an upgrade (!) but how does that prevent burst fittings or other common basement leaks?
