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??
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.
