Hello there. Looking for some advice ref an uneven concrete base. I am
replacing an existing shed with a log cabin garage. Chrcking the levels shows
they are not level enough for the cabin(the approx concrete area is 10m x
4.5m) and i dont want to expense of having to destroy and rebuild as the cabin
only requires 4m x 6m space. The cabin foundation is completely supported from
the perimeter bearer logs, unlike a traditional shed. With this in mind I was
going to create a level perimeter footprint by cementing and achoring a
concrete lintel base on top of the existing uneven base to give the cabin a
solid and level footing with a ramp leading up the 65mm slab for entry. Any
suggestions or alternative ideas? Many thanks in advance.

sounds pretty much the best plan.

The other possibility is to get cheap concrete paving slabs and lay on a
variable depth mortar bed.

Or build a small wooden casting mould with level tops and fill it full
of concrete and build up that way.

ramps as before in either case.

or bricks/stones to sit the walls on, if the amount of unevenness is otherwise acceptable.

The OP could use concrete edging strips - like slabs but narrow and long
on a mortar bed too.

IME preservative coated wood with a layer of felt on top is easier
to adjust for uneven surfaces. Life expectancy 40 years.
