How about a couple of mil of mortar?

Thanks - it’s about 2-7 mill

mortar a good ideal , except at this point something i could slip under it would be far preferable .

appreciate any suggestions

Slate

Great thanks for suggestions .

Would slate not break ?? Now you mention slate - perhaps extremely strong floor tiles ?

thanks again .... huge lesson in measuring the levels correctly I’m the 1st place

Bits of plywood/MDF/OSB/hardboard - anything like that would do - the pressure under each joist is not great.

You hammer pieces of slate in tight, it may break but still has the compressive strength. Google slate packing.
Ceramic tiles may also work but slate delaminates so it can be packed firm.

Are you on about floor joists or maybe steel beams?
