We had nonstop rain for like a month, about a month ago. I started noticing water coming up through my floor towards the end of that month. We just ripped the entire floor up, and the entire floor was wet.
The house is a single wide, with a porch enclosed into the house, then this room I believe is a shed or portable office tied into the house.
No fresh roof leaks. There was some about 6 months ago. The walls don't seem like they are leaking. Nothing in the room that can leak.
Could this much water really just be humidity coming up from under the house?
When we get this much rain, there's no standing water but the ground water is right at the surface, and the house pad isn't built up so the ground under the house is moist.
Do I need a vapor barrier? Dirt under the house to try to keep it from getting moist? Or is this a roof/wall leak I just didn't notice?

trench a ditch around the house to somewhere it'll drain
slope the dirt into the ditch all around your too-low slab

Sounds like he's at the watertable. Only way to fix that is raising the house.
 
You did just have a cat 4 go overhead. Are you willing to pull up more flooring to see if it's coming from a wall with a possible broken pipe?
 
water will wick up block
look up 'rising damp'
you gotta put a vapor barrier in one of the courses of block


ETA: that or you got humiditiy condensing outta the air, running a/c in there? Seen it sometimes where floor joists will sweat from just that

I thought you were gonna recommend a moat. :laughing:

Is the crawl space vented? I’m betting it’s a leak somewhere though.

It'll also run under laminate flooring across an entire house. I'd wager way more on it coming through the ceiling or wall or even a poorly flashed window vs. that much water wicking up through block piers.

The floor is mostly all up. It's mostly dry around the edges where it can breath. There's no pipes or anything that can leak in this building.

Window unit that runs 24/7

I don't think drains will do it. There's no standing water, the ground is just saturated

Any chance that ac unit has tilted in at all?
 
Checked other areas of the house. The ground is wet all around, with a visible waterline on the blocks. This lot flows very well so the water would only be there while it's raining, but it'll stay damp for weeks if we get a lot of rain. Probably not much I can do about that other then the ground under the house and the house being lifted?

I really want to think it's coming from above, but shouldn't I see drywall damage? And it's the entire floor, not just a area.
 
Trust me I know it's sketchy. But none of the roof tiles have stains. (Have in the past)
And the drywall isn't damaged. Also when I first noticed the floor letting water up, I checked the perimeter since there's no base boards and it looked dry all around.
That's why I think it's soaking up from the bottom, but I definitely could be wrong. I'm going to leave the flooring out to see it anything gets wet.

The joint has a membrane that goes up the side of the building. It's not sloped
That wood and random stuff is whats left of a porch that Ian blew off.

I also went around making sure every thing I could find was sealed when I started noticing it.

What's the white pie draining under there?

Right! Like no gutters and the roof draining right on to the window and the siding has a seam right below it. Not staggered.

The other side has gutters.
And that's not a seam under the window, it's sealant. They tried to seal the porch 4x4 to the building. Probably for bugs.

So interesting observation.
It's tilted outward, it's always slinging water and dripping outside.
The inside pan is clogged and not draining out fast enough or at all. The bottom of the AC unit inside had drips. And some boxes under that window has water damage. That can't be enough soak the entire building can it?
