Stagnant water under floor tiles

[RandyCB]

A friend is looking for flooring ideas in a 2car garage. One side will be used for a Toyota Highlander and the other half is a work area and storage.
Living in Oregon with wet winter's, what happens under these plastic suspended interlocking tiles, especially if the garage floor doesn't have a perfectly tapered slab to direct water towards the door?
Does it get moldy or does stuff start growing in the dampness?

IMHO, All of the above.

Would definitely recommend the rib type tile for that much wetness. I have Swisstrax Ribtrax and wash cars in my garage. The water runs out and what little remains evaporated quickly. Although my slab is properly graded. Most all flooring types will struggle with a slab that isn’t properly graded to shed the water.

Leave it bare concrete... Cheap, easy to sweep out and he won't have to worry about mold and other things growing in the garage.

I've never seen anything other than bare or painted, so any flooring is new to me as far as garages go. That said, flooring installation is what I do.
Rib type meaning?

I appreciate the replies. I'm trying to assist a customer and feed them info.

This is one of the reasons why engineering of a garage floor tile is so important, why brands like TrueLock and RaceDeck are 'more different' than what the average guy or gal sees. These products are engineered to allow airflow and moisture flow underneath. You should no more have water trapped than you would without a tile. That said

If there is known moisture issues, the ribbed or flow-through tiles are going to be your best option

Water trapped in the corner of a garage normally gets swept out and allowed to dry. With tiles, you are going to have airflow blocked by the tiles by a major percentage, especially when the doors are shut in the colder days. So how is airflow going to flow under the tiles? I'm just asking curious questions.

Myself....I think the whole water flows away and things remain dry under tiles is a sales hype to sell interlocking tiles. And for the money, I'd rather have epoxy over interlocking tiles as the prices both come out about equal.

I believe you are 100% correct, as I cannot imagine water "not" getting trapped under the tiles.

I've never seen these types of tiles, so I am trying to envision how easily water from a dripping wet car passes between the tiles. I suppose if it gets under the tiles easy, then it might evaporate back up in a somewhat efficient manner.
Concrete slabs emit moisture constantly unless the have a vapor barrier under them.
Customers always say their slab is bone dry, but the reason they think it's dry is because moisture moving out of the ground and up through the slab almost imediately evaporates.
Once you install any sort of solid vinyl flooring over the slab, that can cause issues because the moisture still wants to move upwards to the warmer and dryer area... the inside of the home.
The slab can now become saturated beneath the vinyl flooring because moisture can no longer longer evaporate.
So with that said....... It might explain a bit more why I asked my initial question. Maybe the tiles can be engineered to incorporate miniature fans with microprocessors and humidity sensors.

Maybe buy a few tiles so you can see the underside or go look at pictures online. The tile surface is not 100% on the floor like a mat. There are lower and higher surface areas.
