My basement is not all that big and the area that I intend to refinish will account for around approximately 350 square feet. When I first moved in there was water damage due to broken windows and improper drainage that has all now been fixed (I think and hope as I have been watching for it after heavy rains and what not). As spring is now here and I’m getting sick of not being able to watch my 65 inch TV its now time to being the transformation.

The basement is your typical 1940 cement low ceiling type. It fortunate because the floor supports run horizontal with the stairs so there are no low beams to have to cover aside from the bottom of the stairs. As I wanted to have a nice carpet remnant put down to warm the room up once I stud out and drywall the place. I am 90% sure that the floor will not see water again but when it comes to old houses and unpredictable weather I don’t want to take any chances. Now if I were made of money I would have someone else, but I’m not. I found this GREAT product and actually saw it in the store. The stuff is the greatest, 5/8 thick including a moisture barrio and dimpled rubber bottom to keep air under the floor and allow for the occasional water to just run under it. How great is that! The squares are 2 feet square so that would be 175 tiles to buy for me at (yes get ready for it) $4.75 each. That’s 850 bucks with tax. A LOT of cash for only part of a do-it-yourself basement redo. I WISH I had that kind of money because this product is amazing but I can’t afford it. Is there another alternative for me? It seems obvious that I need a sub floor to keep the carpet both dry and warm and it seems obvious that I need to make sure that there is an air pocked under it to allow water to run to the drain just in case but 850 bucks is a TON of cash for me. I probably could stud, drywall, get my new electric done AND get cans and other lighting for 850 bucks. IF I have no other choice I will just have to wait until I get the cash to get them but if anyone has another alternative that I would be eternally grateful.

Try a product called Delta-FL ( which is just the plastic bottom part to the product you mentioned. They say you can lay just underlay followed by laminate flooring right over top, or just lay down regular plywood...

Anyways, check it out...

Alternative to that would be to put 1x4 PT down with a vapor barrior and then lay plywood on top of that. You will need to either shoot the 1x4 with nails or drill and screw into the concrete to secure the boards.

I am also in the process of evaluating subfloor designs for a basement finishing project. Home Depot has a similiar, if not identical, product called DRIcore ( When I balked at the cost of these 2' x 2' panels, the Home Depot associate said that I could simply make my own larger panels much cheaper.

Home Depot actually sells the moisture barrier material (Delta-FL?) in huge rolls which can be glued to 4' x 8' sheets of OSB. The only disadvantage with the homemade version of the DRIcore panels, AFAIK, is that the 4' x8' sheets of OSB have tongue and grooves on only 2 sides, whereas it appears that DRIcore (and Subflor) seem to have tongue and grooves on all 4 edges.

Anyone have ideas on how to connect the 4' x 8' sheets of OSB together on the edges without groves? I know there are little metal "double-U" brackets which would probably be fine if carpet+pad were to be laid over the subfloor. However, I'm planning on laying down engineered hardwood.

BTW, since each panel is 4 sq. ft. (not 2) you would only need 350/4 = 87.5 panels. Actually, according to the DRIcore installation instructions would need 350/3.3 = 106 panels to account for waste. So the cost would be around $503 (which is still quite expensice :-( )

BTW< 4 suare fee in area

I went to ******* this just last weekend to finally have a look at this 2 X 2 stuff first hand. I also orderd a sample of that roll stuff as well and its not as strong as I would have hoped- thus the reason for going to ******* . Well- I there is no longer any question as to what I will be doing. Spending 500 bucks is what its going to be to get these things. They go together SO easily and the dimples on the bottom are SOLID hard plastic. It’s actually really nice stuff and I would imagine that you would be able to pay your floating floor right over it too. I’m going with this stuff.

I have looked around and getting the roll and placing the wood like you mention over it is just too much work. I think the only way to make sure the plywood is secure is by driving tapcons into it and that would just suck- plus the sample of plastic I got and the 2 X 2 bottoms are not even in the same ballpark. The 2 X 2 ones are SO much better.

Also, just to make it more painful for me. They are 5.75 each. Not 4.50 hehe. Great.

I have been trying to find Dricore all over the place, but it's only available in Canada and the NE states. I'm in Seattle. Subfloor, on the other hand, is available right in my back yard. It does seem easier to work with than the Delta-FL and OSB. Thanks to all of you for the links and tips.
