moisture from concrete (by rani3182 [TX]) Posted on: Jan 9, 2018 10:01 AM

help me solve this issue - I am getting moisture coming up from concrete floor. I used redguard to paint two of the floors before putting carpet, need to do that to the third.

The house is 63 yrs old, no big visible crack in the concrete.

Foundation company tech said nothing wrong with the foundation. Its houston so no basement.

What would you do next? I was thinking i should get the sewer lines inspected to see if there is a leak??? (A camera inspection wont solve this right??)

How much moisture are we talking? Like, the carpet feels damp? Visible water?

Is there any section without carpet and does that concrete look/feel damp?

And, it doesn't small like sewage, right?

It doesn't smell like sewage, concrete feels cold/wet but if left exposed dries out. However if I leave a plastic bag taped, moisture will collect.

House smells a little damp himidity is 70% whichbi am trying to combat --50.202.xxx.xxx

Sounds like the water table might be close to the floor.

Is the house on a hill/slope where runoff might come down and and go under the house? Does it happen more when it rains? (If so, you'll probably need a French drain across the whole house to divert the water flow.)

If house is on level ground there might be a small spring under it.

Odds are, the old floor does not have a vapor barrier under the cement. You might add a vapor barrier (6mil plastic) and pour a second layer of cement over it.

You might also cut a hole in the floor and add a sump pump to lower the water level.

Need more info on exactly how and when water shows up. --23.121.xx.xxx

Assuming it's not a plumbing issue, how well does your house drain rainwater away from the foundation? I suspect that the water tables in that area have risen since the flooding. What about installing french drains 1-2 feet beneath foundation on the low side? If you have to, you can install a sump pump to remove the water.

The fix is to remove the water, not put a moisture barrier on top of the cement. I think adding a moisture barrier on top of your slab would trap the moisture and let it build up inside your slab. Pulling water out from around your house at a level below your foundation will pull water away from the slab. It will also quickly dissipate rainwater too. Make sure you run your downspouts into a separate piping. Don't just dump them into the french drain. --108.69.xxx.xxx

Who you should contact depends on what is causing it.

A landscape contractor could handle the yard. (French drain or a swale)

A plumber or general contractor could do a dump pump install. --23.121.xx.xxx

Maybe a local home inspector might be aware of issues in the area which would cause this? --69.7.xxx.xx

You had a lot of flooding so your water table may be right at the surface. Concrete can probably wick water up through itself. My concrete basement floor only does that when we have had heavy rains. Or the cold of the earth's winter surface is chilling the floor which then chills humid air in the rental and makes condensation on the top of the concrete under the rug. What you do about it is not buy something on a slab. Maybe someone will have a remedy. --73.33.xxx.xxx

I have French drain on 2 side of the house. The water doesn't collect any different in a rain...its a mystery...am rethinking of doing the French drain correctly...don't think it was done right...

I think having the ground wet like it did due to Harvey didn't help as there was just so much water

Is this something recent or has it been going on for months?

Are they getting condensation on the interior of the windows?

What's the outside air temperature? Have you been having exceptionally cold temperatures like a lot of the south?

It's possible that the uninsulated slab is conducting the cold into the living space & the high humidity level results in condensation forming under the carpet on the concrete slab.

Try using an infrared thermometer to check the temperature of the slab, the lower part of the walls & the inside of the windows. --72.93.xxx.xxx

Rani3182 of TX, You can do the French drain around the perimeter of the house. Make sure the gutters and downspouts drain the water away from the house into a gravel pit. Use Dryloc or similar product on the concrete floor. Buy a dehumidifier or have one installed on the a/c unit. --99.56.xx.xx

If you can get the drain all the way around and dig a pit 10 ft away on the lowest side of the terrain place a open top 55 gallon drum in the pit so the drain lines can pour into this, fill with cement rubble, this is called a dry well - google it. --76.188.xxx.xx

I agree with David -- this might be just a humidity issue.

And that humidity, if it stays that high, might be caused by a leak or some other water source completely unrelated to the concrete floor!

If it were me, I think I'd run a decent humidifier for a week and see if the problem goes away (or at least see how often you need to empty it so that you know how much water you're pulling out).

70% is up there! Especially for Texas (when not flooded)!

I have water issues at every foreclosure I buy. Every single one of them. I start with the grading of the property usually. Sometimes it is a very easy fix where I buy tons of cheap dirt and have them dump it where I want in my yard and I rake it out and plant grass seed. That's a cheap fix. Sometimes I have to install a french drain but it has to be done perfectly. Sometimes a large dehumidifier solves the issue. Sometimes Drylok fixes the issue for a couple of years or longer. Also Masonry caulk is your friend for any cracks in foundations.

Other times most of the water was due to gutter issues where the gutters and downspouts are not working correctly. People overlook gutters all the time. Heck one house I had to put a large awning over the basement door and seal it with marine boating rubber and that fixed the issue. Sub pumps in other homes also work wonders with battery backups. Between all these fixes I pretty much have fixed every home of getting a lot of water. Usually every house I have to pick 1-3 items from this list and it does the trick. I had one property last year that took about 7 of these fixes. What a mess that place was. Good luck. --196.52.xx.xx
