Default Waterproofing a concrete floor.

Can anyone recommend a coating to waterproof a concrete floor that is
leaking downstairs from some hairline cracks when it rains? I am
looking for something that can be walked on afterwards. I have seen
some thick rubberized coatings in the past but never thought to ask
what the product was.

Does "downstairs" mean a basement? If so, consider grading on the
outside, so water flows out and away from the home. Then put the
band-aid on. Really, find the source of moisture, first.

Clean, Dig out and repair the cracks and repair the cause of it
instead of hiding the problem. UGL works on walls but ive needed 7
coats on bad walls. Floors I know of nothing myself that wont cause
other problems.

Since you said floor, not walls, that would explain why this thread is so
quiet. It sounds like you have a water table problem. If so, and if you
somehow manage to plug the cracks in the floor, the leak will simply move to
the hairline crack around the edges, where the slab meets the walls. You
could: 1) raise the entire house and pour a new floor, or 2) bust out the
entire floor, install a rubber bladder, repour the floor. Not what you
wanted to hear? Sorry.

You're fighting a loosing battle by the time you get to the inside of
a concrete floor. You need to start outside and try to get the water
away from the house. Gutters, grading, french drains, extending the
gutter drains further from the house.

The important question is why the water intrudes when it rains. You
won't get a good answer unless you provide more detail...how long has
this occurred? Are you new in this home? Extremely heavy rain, or just
"normal"? How does the property slope and is it lower than surrounding
properties? Downspouts drain where in relation to the leaks? Are the
leaks just "wet" or do you get puddles? Getting heavy rain when the
ground is frozen might also cause abnormal conditions.

Around our condo, even though the ground slopes away from the building,
long-term landscaping practices cause gullies to form around the
building that kept water from running off...edging along the building to
keep grass away made gullies and lack of gutters made runoff from the
roof worsen the gullies.

Downspouts draining too close, or improper grading around the house may
be the cause.
