Hey,

there is this yellow drainage pipe, right? Is it only available perforated? From what I’ve seen so far, it was only perforated. I’m planning to install it as a runoff for rainwater, directing it away from the house, right at the top after the bend of the downspout. So, I would rotate the existing vertical downspout slightly to the side and then connect the yellow pipe. But with the perforated one, that doesn’t make much sense if the water leaks out through the holes on the way down. Or do I need to search for a different term?

Currently, I have some kind of hose wrap at the bottom end of the downspout, but the rainwater is still too close to one side of the house for my liking. I want to have it further away. In my view, the end of the downspout is too low, ending just before the ground level, and you would really have to dig a lot to go straight down and then slope away from the house...

I’m not sure what your plans are, but try searching for KG pipe.

No, the underground pipe is not flexible.

I assume we are talking about the shell construction and you want to temporarily divert the water? The hose isn’t bad; it’s sold by the meter. Otherwise, use a sewer base pipe (KG) with a 45-degree bend and a 2 m (6.5 ft) straight section away from the house. If necessary, you can remove a segment from the downpipe, as they are only fitted by socket joint.

Then it’s called corrugated pipe (unperforated) DN 100 and is available at the hardware store

Instead of the membrane, I wanted to install a yellow flexible hose right where the membrane is so that I can lead it away to a distance. Currently, my downspout is there with a membrane attached at the bottom, but there is no slope to allow proper drainage... right now, there is always a puddle there.

The downspout ends about halfway across the foundation slab or even lower.

On the house side shown in the picture, it's still okay... everything is dry... but on the other side of the house, it is more problematic...
