Urgent, the river is on its way into the house

Barriers and strategically dug holes where water can collect or a ditch in front with substantial submersible pumps with hoses to a suitable stormwater drain or similar could work!

The stormwater drains are likely to be overflowing... Otherwise, it would not be the same problem

Lead the water where it doesn't cause harm and is diverted away is my main point, even if it has to be pumped upwards a bit.

If you have or know someone who has a drone with a camera and are allowed to use one there, it is a great way to get some insight into how the house is doing.

don't know if an older house is tighter.

But on the other hand, it's no big news that a wooden wall isn't tight.

But a door is definitely more untight than a wall.

Then, the best thing is to keep the water away from the house. But if that option fails....

On the contrary, in my opinion, the door is likely tighter than the wall. Especially in houses built with natural ventilation.

We experienced a really heavy downpour, something I've never witnessed before. It lasted a long time and was so intense that car alarms went off, so it wasn't just a typical "heavy rainstorm."

Water seeped up from the drain outside the basement staircase. We had about 50cm of water depth outside the door, and inside it flowed along the concrete floor to a drain 3m away. I sealed the door with towels in a panic, which allowed the indoor drain to handle the water volume.

Aside from a few boxes that got wet, nothing more than the floor near the drain got wet.

As soon as the rain subsided, it drained out of the outside basement door drain and we managed with a bit of cleaning. Had the door not been sealed or we lacked a drain, we would have had a lot of water throughout the basement floor.

So sealing doors can really pay off given the right circumstances. But it's certainly pointless in some cases.

Check how it's built for next time. At dad's place and many others with houses from that era (30s-50s, likely more), the drains in and outside the basement are connected to stormwater and downpipes (gray water). So, when it rains heavily, it gushes up into the basement drains. If it's also connected to the regular sewage system (unfortunately not uncommon), it can even be dirty water coming up.

Dad now has the downpipes connected to hoses that lead the water out onto the lawn, so water doesn't come up in the basement.

Check how it's built for next time. At dad's place and many others with houses from that era (1930s-50s, probably more), floor drains in and outside basements are connected with stormwater and downspouts (greywater). So if it rains heavily, it sprays up into the basement drains. If it's also connected with the regular sewage (unfortunately not uncommon), it can be sewage water coming up.

Dad now has the downspouts connected to hoses that lead the water out onto the lawn, so no water comes up in the basement.

Yes, it's on the to-do list. Other water is re-drained but a bit uncertain if we also included this floor drain or cheated. It was done by previous owners. It could also be our drainage that couldn't handle 10 cubic meters of water in an hour.

As soon as the rain stopped, it quickly drained away, so no blockage or anything.

Perhaps NOAQ Boxwall could be something? See https://noaq.com/sv/hem/

On the contrary, in my opinion, the door is likely to be more airtight than the wall. Especially in houses built with natural ventilation.

I suspect that with older houses there are slightly different ways of building.

How did it go??
