You can put a silane (this term covers a lot of similar but varying chemicals) sealer on the
concrete, which makes the surface hydrophobic and has to be replaced about every 5 years or so. Or you can put a traffic-bearing membrane (that’s
vehicle traffic) on top. With only foot traffic, it might not have to be replaced so often. I think both are supplied by any of the large outfits
Or there are at least two products mixed into concrete these days that claims to make concrete hydrophobic, or at least impermeable to water, too. I have no experience with either Xypex
nor Hycrete, so cannot vouch for their claims.
