Pouring a concrete shed base

[britishboy7]

I’m due to pour a concrete shed base, 3m x 3m, 6” deep. Do I need to do anything to prevent it cracking or splitting in half? I’ve poured footings for retaining walls before, but wasn’t sure if it would need anything like rebar or anything in it to tie it together?
Or am I overthinking it (first timer here so go easy)

britishboy7, good evening.

Suggest you consider incorporating a layer of steel mesh for that area you will need a couple of sheets.

Keep the mesh central withing the depth of the concrete [or as near as possible] use Concrete "spacers" to lift the mesh up, old smashed up paving slabs work. keep the mesh away from the edges by [about] 50 / 70.mm
