Hi everyone!
As it’s starting to get warmer, some exterior work will probably need to be done soon! Before I dive into it, I’d like to hear a few opinions from you.
Here’s what needs to be done:
1) Installing curbstones
2) Spreading and compacting lean concrete (sometimes called flowable fill)
3) Paving the terrace and parking areas
4) Building a retaining wall
5) Garden shed
The priority is to pave the surfaces first to keep dirt away from the house.
For that, I should first install the curbstones and then fill with lean concrete.
Can lean concrete be left as is after compacting, or does it need to be leveled immediately with gravel and then paved?
(We already roughly backfilled and compacted during the groundwork, but it’s quite uneven now.)
Should the drainage channels be installed first and then compacted around? We definitely need one at the parking space facing the street. What about the terrace? At the house, along the wall, or both?
I have a wastewater connection at the heat pump, but that would require quite a lot of digging and curved piping now. Would it be an option to connect directly to the existing house connections instead? (Basically just cutting a piece out and installing a Y-connector.)
Thanks in advance for your input

I would always use a rainwater catch basin for drainage. It’s easier when it comes to maintenance and inspections.
Then, depending on the ground conditions (my advice applies to well-draining soil), I would direct the water to the soakaway using perforated corrugated pipe. You can already buy it online with a protective coating (not the coconut fiber type).
For the main drainage pipe carrying rainwater (not the house’s wastewater pipe), you can safely expose it, cut it with a cutoff tool, and connect it using a Y-junction and a slip coupling. Remember to use lubricant and to bevel and deburr the edges.
I’m not familiar with “mineral concrete” as a base layer; normally, recycled material is used. Either regular recycled aggregate (not recommended), certified recycled material, or high-end users choose natural stone recycled aggregate. All three are mixtures ranging from 0 to 32 millimeters (0 to 1 1/4 inches). Wet the material well, then compact it with a plate compactor (this protects your lungs and the air filter, and it seems to provide better stability).
What exactly do you mean by drainage channels?
Try to phrase your questions more clearly :P
Also consider whether you want to pave the area—personally, I found it too much work.
On YouTube, there’s PAPA Mike, who uploaded two videos about a year ago: one “Guide to preparing the base layer” and one “How to properly install curbstones.”
He seems like someone who acts first and thinks later. The Hornbach Masterclass videos are just frustrating to watch because everything always works out perfectly for them.

Thanks for the tip!
Unfortunately, we are on clay soil, so nothing seeps away. That’s why we are using the cellular concrete; otherwise, gravel would be used. (At least, that’s what I’ve read.)
By drainage channel, I mean the channel where surface water collects and can then be directed into the sewer system.

By drainage channel, I mean the channel where surface water collects and then drains into the sewer system. Permeable pavers or these channels with grates? They are about as deep as paving stones and get integrated into the paving.
