How to stop moisture coming through concrete basement floor

Q. I have a 45 year old home with what once was a finished basement. We had a sump failure last summer. The floor and 2 feet of drywall was removed. Left was a concrete foundation with no floor drain. I have noticed since it has warmed up moisture coming up through the foundation. Moisture meted shows 45 percent in basement. Can this concrete floor be sealed before I re-do the sub floor? Please advise. Thanks Anne

A. One of the first things you should check is the soil & landscaping outside the foundation. Make sure it all pitches away from the foundation so no water puddles next to the foundation walls. I have written a page about basement floor waterproofing that should help answer your question.
