Small water seepage through floor crack

[inseine]

Hi, I’ve been reading everyone’s advice here for a while, and I am hoping to get some advice. I have a 24x24 garage that was built in 1974. I want to coat the floor with a high solids epoxy and place a urethane clear coat over the epoxy. The floor has had quite a bit of cracking from heaving in the past and I have fixed things by removing all the loose concrete, chasing the cracks, and applying epoxy concrete patch.

The problem is I have two tiny places where I get a bit of water seepage from underneath. It is just enough to make a .125” spot on the floor with no actual water that shows. I know this because the patch doesn’t stick here.

How do I fix this? All the products I’ve seen need to have a dry surface to adhere. I was thinking of grinding out that area deeply, apply something, and then place epoxy patch on top. Is this something that would work? Also, what product to stop it?

Thanks,

Jeff

My brother in-law had a similar problem except he was getting water on the floor and actually wicking up the drywall, which the lower 4' had to be replaced. We dug a 3' deep trench around the perimeter, put down some crushed stone and layed in a sleeved, perforated 'big O' which was connected in to his storm drain.
This was all part of a much bigger project which included 30 meters of new concrete for a new driveway and walkways. By keeping the frost prone areas dry and eliminating the seasonal ground water level and pressure, the floor stabilized and his crack repairs in the garage are holding up well.
I think you will have to correct the underlying problem similar to how he did. A bandaid repair, just fixing the cracks may not be enough.

I hate to rain on your parade but based on your description I wouldn't invest in an adhered floor covering. Cracking and heaving aside, the obvious lack of a vapor barrier and active water intrusion severely limits your chance for a successful installation. Maybe a floor tile like RaceDeck would be a better choice.

Thanks for the advice. I’ll reevaluate my options.
