No, it has nothing to do with how you assemble it. The house itself is not waterproof. So blocking doors and windows won't help.
If it did, the house would also float away.

Well, if I had water a few meters away from the house, I would also block the doorway... If there is material, the next step would be to lay plastic along the facade and weigh it down against the ground to try to seal it. Alternating with moving as much as possible to the attic, placing beams under furniture, and crying.
If we're talking about an entrance door in a wooden villa, it's of little to no use at all. Focus the energy where it has the potential to be beneficial.
It's about buying time. Since windows and doors are usually made to be opened, they are not a wall, so naturally, you would block windows and doors.D Daniel 109 said:
No one said you could stop all the water.
I would have covered doors and windows. It gives me time.
If we think about the physics.
I'll make it simple.
We know that houses are not directly sealed. Depending on the type of construction, concrete frame is more sealed than wood.
But if we take wood, a common building material for small houses.
Wood is relatively sealed against water. However, there are many joints where water can seep in. Windows and doors are where water enters most easily. Openable windows are even worse.
The water easily enters between the wall and the frame. There is nothing there to stop it. An exterior wall has a bit more to stop it before it enters the house.
If you now place a board in front of the windows, it becomes another barrier for the water. This means it takes longer.
Time is important. You have a better chance to remove a lot of the water.
If you place a board in front of the door, the water is slowed down.
It becomes another barrier.
Then there is another important reason to use the board. It is quite possible that the water will press with a certain pressure. The board provides protection there.
Boats are sealed; they float away.
Yes, houses can float away. What do you want to say with that?
Should I not protect my house because of that?
You know that cars can also float away.
Do you understand why the wooden board can very well offer protection?

It's still good that you're there with an answer every time someone is wrong. One becomes really curious about what you are not best at and why it only says "member" and not "god" or at least "omniscient without fault" on your profile.D Daniel 109 said:
Walls are not dense. It doesn't work.

I don't think he's wrong this time, in my opinion. A modern wooden house is at most tight on the inside, I don't really know if I want the vapor barrier to build a water column inside the wall.F fsn said:
No, that's what I'm saying. Damn nice that he's there to straighten things out every time.S SueCia said:
Good that you clarified that for us.D Daniel 109 said:
In case anyone was wondering.
don't know if an older house is tighter.S SueCia said:
But on the other hand, it's no big news that a wooden wall isn't tight.
But a door is definitely more drafty than a wall.
Then the best thing is to keep the water away from the house. But if that option fails...

Yes, I didn't mean that older houses were tighter, rather the exact opposite. In older wooden houses, there's nothing that can be called tight, but in newer houses, the vapor barrier is very tightBananskalare said:
I wouldn't bother making any attempts if I couldn't stop the water from reaching the house, I'm convinced that it will make negligible difference as it only involves a difference of a few minutes before the water level is as high as if one hadn't tried.
Raising furniture and valuables from the floor is about the only sensible thing. Unfortunately. (unless one has the opportunity to divert the water away from the house, of course)
With a little foresight, a barrier can be built against the water. A wooden construction with a profile that looks like an upside-down V. That is, a wooden sheet against the water supported with braces on the backside. If the terrain is uneven, plastic can be placed on the sheet and the lower part buried a bit into the ground.
This is not difficult given that it doesn't get too deep, as the water pressure per meter of barrier increases with the square of the depth. At a 45-degree angle, the pressure on the sheet is h^2/1414 kg/m if h is measured in mm. Note that the pressure is greatest at the bottom and none at all at the top.
If the water rises to 300 mm, the pressure becomes 64 kg/m, 500 mm: 177 kg/m, 1000 mm: 708 kg/m.
If it is not watertight, there is a risk that the water will dig through under the barrier and everything will be destroyed. But if it just seeps through the soil, it works well. Especially if you let the plastic go down to the ground a bit since the water pressure will press the plastic against the ground.
If it rains heavily or seeps a lot, you will still get water on the wrong side of the barrier. If there is no natural drainage, the water must be pumped away. If there's no electricity, it can be solved with a fuel-powered generator or a fuel-powered pump.
For those who think that the whole barrier will be pushed away, the V-shape makes it be pressed down toward the ground by the water pressure.
A faster variant could be tilting the boards against the house and laying plastic on them. But then you can't see what happens underneath.
