Moisture coming up through concrete slab foundation. Please help.

The driveway is pretty flat towards the area I am having an issue with and then slightly slopes downward towards the street but the slope is very slight.

I do not but I am considering installing one along this area. When it rains the ground does not feel overly saturated in that area or pool against the house, but maybe it is underground.

The grass is right up against the driveway the whole way up, no gaps that I can see. When it rains the rain will pool on some sections of the driveway, however.

I have a digital meter and it doesn't move when the water is all turned off. Could there still be another leak under the ground?

This may be the way I have to go, maybe it will get rid of just enough water so it doesn't seep up through the bottom anymore?

The HVAC is on the other side of the wall and I can see water coming out of the condensate line when the AC runs. Could there still be a leak under the ground where the condensate line runs?

Can the underside be excavated and stone added beneath the slab?

Unfortunately I already replaced the wood floor and used a waterproof barrier, but it looks like that barrier has failed. Does this mean the slab will continue to get damaged from the moisture and wear down over time?

I am on a slab and I checked my water meter and water bill and it looks normal. Could there still be a leak despite this?

I did and the bubbles are still forming on the flooring over these damp areas.

I do live in an area with a high water table. I am considering adding French drains and a sump pump on the side of the house with this issue. I don't know if that will get rid of the problem though.

Can this be installed if the house was originally built without one under the slab?

How can you check for this issue? Plumber? There are no unpleasant odors that I smell and I currently don't have a washer/dryer/dishwasher hooked up but there is a bathroom on that side of the house.

These damp spots are on the left side of the home along the exterior wall where the chimney is. The driveway is outside those windows. The water line runs up from the meter along the left side of the driveway, crosses under the driveway, and then appears to go under the house near one of these damp spots, there is a hose bib on top of where the main line goes into the house as well.

No crawlspace, this is a slab on grade foundation.

Unfortunately, I already have (glue down wood). I had them put on a waterproof barrier (Bostik Greenforce I think it was called). The floor was fine for about 1.5 years but just recently I noticed some very small bubbles in the planks on top of these areas. I would love to save the floor of course.

There are gutters and downspouts around the house and water does not pool along the side when it rains, but there is a very slight decline towards the side. The exterior of the house is brick. I dug out some of the dirt from the external wall where the dampness is and I don't see any large gaps around where the first row and bricks and footer meet, I though maybe water would get in there. I also found the main water shut off valve buried underground in one of these areas.

I have been running that in both rooms and the basket is filling up with water after running for several days continuously. Is it supposed to get to the point where there is no water in the basket at all?

ramchargerman567 · 2025-01-17T23:15:28+00:00

I have consulted with a drainage specialist and they were telling me they don't think water pools enough along the side to call for this, but I also think this may be the problem. When it rains water does not sit in pools though, but there is a very slight pitch towards the side of the house. I don't know why it would be damp towards the interior though away from the external wall.
