Waterproofing Flexicore Floor -Epoxy or Sealer?

[budwisr]

I have a 3 car over/under garage which uses flexicore for the upper garage floor. Some very thin cracks have developed in the concrete over the flexicore which allow water from the upper garage to drip through the seams of the flexicore in the lower garage. I am wondering if an epoxy paint would seal the hairline cracks or if a concrete sealant would work better. Any recommendations or advice would be appreciated. Thanks. Bud

Crickets...


Maybe I should rephrase my question. Will hairline cracks in concrete (the kinds that are present in all concrete) propagrate up through the epoxy or sealer? Thanks in advance.

maybe you should rephrase your question :

will flexicore cracks cause my ceiling/floor to collapse ?

i have a condo(apartment) that has flexicore. there are no cracks what so ever.

what are you spans ?

LOL The cracks in the lightweight concrete on top of the flexicore are what I'm asking about. But thanks for your concern.

Epoxy coating will probably not fill the cracks. Use a gel crack filler for this.

This looks interesting although the crack shown is larger than what I'm dealing with. I'm assuming that this would work best with an epoxy, correct? Bud
