Hi again all in here.
For various OT reasons I have decided to put my 3 tonne 4 post lift outside
and to use a 2 post inside my barn-to-workshop conversion.
So, I need to make a slab for it. I think probably the same 6 inches of
hardcore and 6 inches of concrete is probably still fine, but I wondering
about how to lay it seeing as there wont be any walls around it. Should I
just level the gound off and put the hardcore straight onto that, or should
I 'sink' the whole thing into the ground? Cant really see any need to do
that. Should I still blind the hardcore and put the plastic sheet between
hardcore and concrete?
The ground gets very soft in the winter, so I figure I need to make the
hardcore base quite a lot bigger than the concrete slab. What I don't know
is how much bigger the slab needs to be than the lift? Should I allow say 1
foot all around, something like that?
Thanks,
Conrad
