Base for shed, but need to raise the level first

[Ticky]

Hi all,

 

I need to level out an area so I can place a shed onto it.

 

Currently, there's a 3m squared area that's about 40-50cm deeper than the rest of the land. I was about to order enough MOT to fill it but then remembered I may be able to use broken concrete to build up first.

 

I'm sure I've read that if I wanted to build up the foundation I could lay some geotex fabric down, lay some bigger aggregate (I've got some concrete slabs I could break up) followed by some MOT and compact along the way.

 

Is this correct?

 

Also, I'm unsure if the fabric was supposed to go as the first layer directly onto the undisturbed ground or as a second layer after the large aggregate.

 

Thanks in advance

I wouldn’t bother with the textile, hardcore (bricks, rubble concrete etc.) well compacted and then cap off with MOT.
