All,

I need to lay a concrete slab so that the 12ft trampoline in the garden is level. HOwever this is my first attempt at anything like this.

At the moment it is just sitting on soil butI can see this sinking in the wet weather so want to lay a concrete base for this but am unsure if concrete can just be poured on top of soil and how deep it would need to be.

Also if it would need to be a certian type of mix.

Any advise would be greatly appreciated.

I'd be tempted to lay a slab at each point where the trampoline base requires support as it will take less time, involve less digging and will require less effort to remove when you're kids have gotten bored with the trampoline.

Obviously you'll need to make sure that all the slabs are level with each other when laying them but IMO it would be less hassel than laying a concrete base.

If you do want to lay a base then I would say you'd want to dig a pit down for a few inches, even better would be to go down further and lay some compacted hard core first.
