We are glad it helped!

Hi Bob. A malfunctioning meter will not cause the problem. What we are saying is to check the meter to see if any water is passing through when you know for a fact that there is no water being used for the property. If the little red wheel is moving, then water is leaking from a pipe. We are guessing you have a problem somewhere unless you live in an area where it’s not uncommon for groundwater to come to the surface from time to time. You may want to have a good plumbing company with leak detecting equipment come to check it out. We don’t envy your position. It’s no fun trying to source a water issue.

Thanks. I did have the utilities people come out and check the water meter. They found no problems with that. I’m the original owner of the house which is 24 years old. Never had this problem before.

Hi Bob. You are positive that your slab is above grade, correct? It’s not a few feet or so away from a dirt bank with higher ground or anything like that? Water drains away from the house and does not sit up against it? No planter beds up against it either? If not, then the first thing we would recommend is making sure you don’t have a leaking water line, drain pipe, sewer line, leach line, or anything like that running under the slab. It’s a bit unusual to have moisture under a slab that is above grade. The fact that it seems to be getting worse is concerning as well.

One way to check if you have a water pipe leak is to make sure that all water sources are shut off within the house and not running. This includes outside water as well. Then check your water meter outside. If the little red wheel is not turning, then you don’t have any leaks. If it is turning, then you do have a water leak. Plumbers also have leak detectors for drain lines and sewer lines.

If all checks out OK, then the only thing you can really do at this point is to apply a densifier to the concrete when it is dry. This article here explains how they work and includes a product we like. Many times a densifier treatment will slow down moisture intrusion and sometimes even stop it. However, you can’t completely waterproof concrete at the surface from moisture coming up from below. The only way to do that is from under the slab, which of course is too late to do at this point. It needs to be done before the concrete is placed.
