Floor buckling and crawlspace moisture problem
Posted on 8/31/19 at 5:12 pm

My floors are buckling. I have a raised home. Apart from making sure there are vents under the house. Is there anything i should do?

Have the floor or anything else changed lately, inside or outside the home?

No nothing has changed. The previous owner poured concrete basketball court right upto to the house. I have a suspicion that the water is flowing towards the house under it instead of away from the house.

It is wet under the home?

You need to go or look under house when it’s raining and find anywhere water is getting under house. Find a way to stop it. I was able to wait until winter when the humidity went down and the floors went down, then I had the underside spray foamed. No buckling this year.

Yep. I'm going to install vents every 5 feet in the front of the house. The back of the house is open apart from slabs.
Any other suggestions

Did you do the spray foam yourself or used someone? Can you provide me with the info. Thanks alot.

I used Mr Green jeans to do the foam. I want to say it was around 1.80 sq ft or so.

Closed conditioned crawl space with a sump pump no vents. Too much rain and snow where you are for open crawl, not that I would recommend open crawl anywhere.

Bought it 4 years ago. It started every year since we were in the house. Looks like they fixed the floors and sold it. My inspection guy must be the worst

You located in Louisiana or the Deep South, or Denver? Either way, you need to read this publication to better understand your issue of moisture and wood floors cupping and solutions to the problem as already suggested by others. Insulating Raised Floors in Hot, Humid Climates
You can/should consider a dehumidifier(s) in crawl space to begin the process of drying the wooden floors.

you don't have an insulation problem, or a venting problem. You have a water problem. Find and stop all sources of water getting under your house. Let it dry out. Then wait and see if floors unbuckle.
A/C drain lines, water supply leaks, water coming under the house from outside, sewage leaks....anything else you can think of that moves or creates water. Inspect every square foot, remediate accordingly.
If your house is already open in the back, more vents in the front will literally do nothing. zero. zilch. nada.

thank you

You guys are right. I'm not a handy man at all. But thanks to you guys, I found 2 issues already. I have 2 AC units and one of the drain pipe is not routed all the way out. It is just left to drip under the house. I'm going to route that PVC out. Should I route it onto a flower bed or where the gutter run off is? Any ideas will be appreciated..
The 2nd Issue is that all the rain that just happened in BR. I went out to inspect where all the rain is going. It is flowing from the gutters under the house. How do I make sure I slope that water away from the house into yard.
Any advise would be really appreciated

Main thing is that you need the earth sloping away from your house so that it will all drain away and not under. You can also use catch basins below the downspouts to catch water and drain it away from house with pvc. But even with that, you need to make sure you have proper grading so that rain collecting on the ground doesn’t flow under.

Yep. My grading is all messed up. What kind of soil and material should I use?
Posted on 9/1/19 at 8:19 pm to glorymanutdtiger
without being able to see a photo, in general I would prefer to remove soil - not add soil - to create a swale around the perimeter of the house several feet from the house. Gravity will always win, so if you add soil around the perimeter to make it higher than the yard, it will also make it higher than the crawlspace floor, potentially leading to water finding its way back underneath the house. Basically, you want the crawlspace floor to be the highest point in your yard if possible. If that isn't possible, french drains, gutter pipe extensions, etc, could all be options.
I don't know what kind of soil to use if you want to add. The previous owner of my pier and beam home ran gutters under the house from the high side to the low side on a sloped lot. Great idea to move all of the water coming off the roof from the high side, except that inevitably, the gutter pipe joints will leak. Being under the house, it could be a very long time before it is noticed. I finally noticed it after having many simlar problems as yours.

You need to get the moisture issue resolved quickly. I took my time with moisture under my house and floors buckled permanently in some areas.
