A small base for an Aircon Unit

[JohnnyUK]

Hi

We're having a/c fitted on Monday and MrsJohnnyUK insists the unit is put on the ground, as opposed to the external wall.

I've cleared away the existing pea shingle and on the advice of the fitters, put down a couple of bags of Postcrete.

There's still some way to go to make it level with the paving slabs.....ignore the black irrigation tube.

Would you finish with Concrete Mix or Mortar. ChatGPT suggests the latter.

Thanks!

I'd have thought a bed of concrete, and thats what I would do if it was mine, but im by no means an expert.

Why not use a bit more Postcrete?

Postcrete is meant for underground/inground,
Wickes etc probably sell premix aggregate
add some cement mix etc.

Mine just sits on shingle on rubber feet like this;
