basement aerated subfloor like dricore

Hello,
I have a concrete slab under my house, which has been boxed in so its two large rooms.
In extreme weather events with a lot of water some moisture comes through the slab.
I have waterproofed the surface of the slab with an oxtec product, which has helped, however I want to lay some hybrid vinyl planks.

To prevent mustiness, I would like to place an aerated subfloor beneath the vinyl planks to provide some airflow.

I have found various dricore products used for the same reaosn in the us - but cant seem to find it here anywhere.

Another alternative I thought was to use something like this -

Ive been trying to find something with a low profile to keep the height of the floor down

Any ideas, or issues with this?

Thanks very much

I did just find these and was wondering what you guys think of these for the purpose?

The Norsk ones are very low profile (6mm) while the others are 18mm.
But maybe the 18mm would have better airflow.

No experience with sort of thing, and wonder how it will truly make a difference under vinyl planks, unless there are fans to move the air from one side to the other, or the floor is perfect for runoff to where evaporation can happen, but the 18mm looks like it is the better option. Just because more room for air would be better, but then again the 6mm has a graphic depicting airflow :)

Consider cleaning.

Dust will fall into the gaps and eventually fill them and they will be impossible to clean with a broom. Do you have any pets? If so, and they are prone to dropping little bundles on the floor, you should be mindful of which tile will be easier to clean.

Anyway, I'm not so sure this is a great solution for a basement that leaks water. Seems like you are simply hiding the problem. If you get the place waterproofed you won't have any need of tiles. If moisture develops and remains under the tiles you may have a mould problem. Some moulds aren't too good for our health.

Thanks guys,

I don't think dust will be a problem as the vinyl planks will prevent that.

Mostly seems to be a us thing where they have basements below ground.

There isn't any water flowing, just gets a bit of efflorescence and damp come through, which i have waterproofed.

Just after a bit of insurance really before i put down the vinyl flooring.
As in, probably better to have some airflow than not.
Will double the floor cost though !!

Are vinyl planks thick and stiff enough to not show the texture of those tiles as an underlay?

Good point but i still need to put the vapour barrier between the tiles and the planks. This has a 2mm rubber underlay built in so solves that.
