ᐅ Material to fill the approximately 2-meter-deep space beneath the new terrace

Good morning,
In spring, a new terrace will be built next to our house.
Currently, there is a room under this terrace with a 5,000-liter (1,320-gallon) oil tank, which will be removed soon since we are switching to gas heating.
I want to fill and compact this room (2 meters deep (6.6 feet); 2.5 meters wide (8.2 feet); 3.5 meters long (11.5 feet)) so that we can later lay terrace slabs on a gravel bed above it.
My question is about the appropriate material to fill this space.
The terrace should not sink later on the compacted base. Of course, the terrace slabs will still have their own separate gravel and crushed stone bed.
- According to online sources, a mineral material is definitely recommended. Crushed stone would be suitable here.
The angular stones interlock when compacted, providing stability.
- A friend recommended sand as a filling material, since it prevents air pockets.
What would you recommend?

I just calculated that I need 24t (24 tons). That’s quite a load.
It definitely makes sense to consider a small wheel loader/bobcat.
PS: A mason friend recommended recycled concrete to me. It should be frost-resistant and easy to work with.
Thank you

Concrete recycling recommended. Hello
This would be the most cost-effective option and perfectly suitable.

Thanks Yes, it’s a hefty amount, but definitely doable. Five years ago, I moved 32 tons of clean gravel by myself using just a shovel and wheelbarrow (simple distance from road to “destination” was 30 meters (98 feet)).
If you want to do it quickly: 5 friends with 5 wheelbarrows and a mini excavator to load the wheelbarrows.
