theChaoZZ4 Mar 2021 08:28Good 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?

According to him, anything else would always cause the ground to settle further. So we ended up using tons of it.O

How will the material be delivered to the exact location you need it?
Ideally, have a saddle load of sand delivered and installed in layers.
Then filling the rest with crushed stone should be sufficient.
Ask the local supplier about prices. In some regions, crushed stone is scarce, while in others, sand is in short supply...

theChaoZZ4 Mar 2021 15:10The house is detached and fenced. The supplier would probably dump the materials in my driveway, and then it will be moved by wheelbarrow to the excavation site (distance about 70m (230 ft)). I will definitely have to recruit a few friends for shoveling and transporting :-D
What advantage does mixing sand with gravel have compared to using only gravel (regardless of price and availability)?
Thx

You won’t have any friends left after that.
Consider alternatives.
Then we can talk about materials 😉
(That distance alone is more than a marathon... and with a wheelbarrow. At least get a small mini excavator to load the wheelbarrow if nothing else works.)

Fummelbrett!4 Mar 2021 16:19Mini excavators and dumpers — or better yet, a tracked dumper with a bucket. Shoveling by hand is really tough work. I’m speaking from experience(s).
