Slab leak fixed - now what??

We have a lot of residual water under the concrete slab after re-routing a leaky pipe. Carpeting in a 500-600 sq ft area has been removed. After 3 weeks with dehumidifiers and fans we still have excessive water vapor as measured by a calcium chloride test. (the slab doesn't look or feel wet) We have lived in the house for almost 30 years and have never had any moisture problems until the leak.
Any ideas on what to do now??

Mitch,
If you've lived there 30 years, and the leak has been fixed, then just ignore the moisture and go on living. If it's going to bother you, you could put in a sump pump & pit, but unless you've had problems with a high water table, it's probably just a waste of money.

If they build slab homes in your area the way they build them here, and you are telling my you had a leak that has been repaired, I would recommend that you drill a hole all the way through the the gravel bad that is located underneath that concrete slab. The gravel is probably saturated with water. By drilling a hole (or many holes) it will give water trapped in the gravel bed a place to go and the concrete itself will dry out. It will take some time though. Bear in mind that there is no air circulation for that bed of gravel so things aren't going to dry out overnight.

depending on local building codes some areas require plastic between the soil and conc. this would hold water for a while but should evaperate after a while
