Need help and advice..

Hello guys

I had a fish pond that was 24ft wide by 17ft depth with 2 feet steel beam supported walls ... it was built like 60 years ago .. i removed the walls using a kango and i took it down to its base level and all that i had left was the pond slab of concrete.. i built walls all around to the height i wanted and infilled it all with what i earlier removed and used this as a hardcore base.. i have spreaded sharp sand on top to level it all off. my aim is to create a patio area and a place to house a 16x12 shed . what i need to know is this

1. Is what i've done suitable enough.
2. can i just lay the slabs on top and will this be sufficient as a patio area
3. can i just dry lay the slabs or do i need to hold them down with concrete dob&dab to hold them down.
4. Will this be suitable enough for the shed to be placed on.

Please forgive my severe lack of knowledge lol.

1. Its a start but not all u need to do
2. Yes and no, respectably
3. Yes and no, respectably, although neither if you want it to last.
4. Yes

As its your first post can I suggest using Search, as it will find all these questions answered in more detail. Have fun.

17ft depth with 2 feet steel beam supported walls

Did I just read that right. Seventeen feet deep and walls - what? Two feet thick with steel beams in them? That's one hell of a fish pond!

Edit: Sorry, too much sherry. Did you mean 24 x 17 ft and two feet deep? Well. as I understand it - and it's borne out by experience - when you re-fill a hole only two thirds of the original material goes back in - unless you compact it very thoroughly. Did you do this?

lol yes sorry 24 x 17 and 2 feet deep lol ..

i've used the search and read through the forums since yesterday and could not find anything directly relating to what i have done.

so what do i need to do to make it a solid enough base to lay slabs on ??.

I'll post a couple of pictures of what i done so far as soon as i work out how to put them on in the right size lol
