Enough screed to support weight of car

[Post and beam]

The wooden workshop/garage that i am having built might one day get used to put a car into, radical i know.

Its primary use will be for tinkering about so i will probably insulate under the floor, just like the house.

Does anyone know if a 50mm screed onto PIR would support a car? Or do i need more or something different.

Thanks in advance

yes will be fine as long its not a tank!

Well, old Merc's were built like tanks

Also what about point loads (jacking a car up etc) personally I would want 100mm (but I do tend to over engineer things). Steel or  fibres would help I guess).

Very expensive to do twice. 
I’d put 100mm down, impregnated with steel fibres. Not a huge difference in cost, but a huge difference for the end result.

For my underground build with parking above this was tricky ( specifically the insulation ) .

Think I did 150mm screed with rebar . This sat on vac insulation which in turn sat on 200mm concrete and rebar .

All part of my mega plan . Human race destroyed . I then rise out my bunker to dominate the rather empty world with my presence .

You need to offer shelter to several fit, young, good looking females. Otherwise, it will be a very dull new world for you.

Point load will be your issue when the slab becomes a beam and bending occurs. 50mm is very strong however I would go 100mm and then chuck fibres in (steel or fibreglass will do) and it won’t go anywhere.
