I would hesitate from putting up more drywall and covering up the issue with a gap until you are 100% sure where the issue is coming from. I would find it hard to believe your water table is so high that water is leeching up through the concrete and not leaking into your basement. Could you have a drainage issue but the water proofing of your basement is keeping the water at bay for the time being.

Have you thought about tearing up a small area in the garage floor to see how wet it is under it?

I'd pause a moment and get an inexpensive humidity meter or two and place one near the wet area and another in the opposite side of the garage.

Take readings for a week or two and see if airborne humidity levels in your garage coincide with appearance of wet walls.

If there is a significant difference in relative humidity from one side to the other, that would tend to confirm an outside source but if they are the same could it not be condensation from the air causing all this?

Did you ever try the Xypex? I was curious if this stuff actually works

I centered the garage door weather stripping that is under the door to close up that gap. There hasn't been any hard rain in the last few weeks, so I am anxiously waiting to see what happens during the next hard rainfall. The water would have to run in through that opening and along the top of the foundation wall all the way to the back of the garage closest to the garage/kitchen door? If that foundation wall has sunk any and is now lower towards the back of the garage, I guess this could occur? I hope this is it!

Where can you rent/buy a moisture meter? I asked at Home Depot and they looked at me like I had 2 heads?

I haven't tried the Xypex yet, mostly due to not having gotten to it yet because of work. I want to try all other "simple" options first before getting into this project. This could take me months to finish, I am only a weekend warrior when it comes to renovations.

I am finding that the garage floor is not as dark as it was last year after a very hard rain. Can the water table vary this much from year to year?

I think I've (with the help of the awesome team at DIYChatroom), have narrowed it down to the following;

-> ground water coming into the garage via the gap caused by the shifter garage door weather stripping.

-> ground water coming in from penetrating the exterior face of the foundation wall exposed to the elements.

-> varying levels of moisture in the garage itself, due to AC running and higher humidity close to the kitchen/garage wall.

-> rain water was dripping in behind the eavestrough and the fascia in a large number of areas around the house. This may have caused excessive ground water close to the foundation wall which could have worked itself back to the garage. I am getting new eavestroughs and down spouts put in next week to eliminate this possibility.
