Hairline Cracks in Basement Floor

Question: After removing the carpet from our basement floor (following the heavy rain) we discovered several hairline cracks. After two weeks, moisture still appears to be coming up through the cracks due to hydrostatic pressure. How do we seal the cracks so that we can lay vinyl flooring?

If the hydrostatic pressure is high you may not be able to water proof your floor, a high water table usually requires an outlet such as a sump hole and pump. There are water proof sealers available that would certainly help against moisture but are limited against pressure. Also, be sure to check out water sealer products at your local building supply store.
