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?

thank you for pointing out the quantity.
When transferring the measurement sheet and calculation form, a width of 3.5m (11.5 feet) was mistakenly changed to 2.5m (8.2 feet). Of course, that is incorrect.
Without your note, I would only have noticed this when filling the hole. Thanks to you!
If we have the hole filled, I know it will be done properly, and we were also able to negotiate a better price with the construction company.
