Now that we have removed the wet carpet from our basement floor, we
can see a few cracks in the concrete.

Although the recent mini-flood was caused not by water coming up
through the cracks but by water overflowing into the house from a
flooded window well, ought we to fill the cracks before laying new
carpet or carpet tiles?

Let the concrete dry thoroughly. It may take a few weeks. You may need
a fan and a dehumidifier.

Fill large cracks with mortar. Every slab has hairline cracks. Large
cracks, especially those where the two sides are different levels,
should be examined by a foundation expert.

Seal all cracks with something like RedGard.

Thanks for the reply.

The cracks are little more than hairlines. Most of the floor already has
some kind of coating on it, but I have no idea what it is. Will the
RedGard work on top of an existing coating?
