Pour the ground slab in sections?

Okay thanks for the hint. I will then make a drawing and send it to them. Alternatively, I will ask around regarding the delivery of damp concrete. The problem is that I think it won't be cheaper with the wheel loader, since it has to be delivered to me. Unfortunately, I don't have a trailer. But I'll look into it and report back. Thanks anyway

I paid 200€ including everything for an Avant via eBay Kleinanzeigen from Friday 4 pm to Monday 7 am. Many small companies rent out their equipment cheaply over the weekend before it just sits unused in the yard. With delivery, tax, insurance, fuel… it's especially worth it if you still have two or three small tasks to do. Moving a pallet of stones, leveling something, shoveling something into a container.

Be careful with sloped surfaces and highly flowable concrete. That goes wrong.

The thing about going wrong indeed happens when the concrete is highly flowable – then it will tend to level out.
