Concrete or no concrete

We run ours on concrete and have had no problems but it is 8"-10" thick.
The conveyour belt would work just fine.
If you plan to use it just for storage i would save the money and do a gravel floor but if you plan to do any reapir work concrete is the way to go.

four pieces of heavy timber sheathing that each are the length of the track works well too to save the concrete.
if the machines are only driven in and out on a straight line others have embedded RR track even with the top surface of the concrete---if you have different gage widths that might be a problem
If you go with concrete add mesh or rebar--concrete always tends to crack either from loading or from shrinkage and the steel will keep the cracks tighter.

if gravel you will probably have to regrade where you made turns.

Steel?

I noticed the British Tank Museum at Bovington UK - also home for the Army's tank Regiment - uses steel sheets embedded into concrete flooring.

It was fun to see them drifting the combat tanks in and out of the shed area on a wet day.

When we poured the floor in my Buddie"s work shop for his construction business, we poured it 10 inches thick and put radiant floor heating in it. Makes a great floor to work on with a creeper, takes a while to warm up big iron (he has a D8, D6 and JD 550 for tracked machines. He lays down a couple of rough cut 2 X 12 oak planks to keep from digging up the floor surface. Machines need to be inside for a couple of days to warm up to room temp.

Compacted screenings work better than gravel for me, easier to walk on

There is a dozer grade concrete, I think its rated at 10,000 lbs. test. You can run on it with most dozers and excavators with out tearing it up. This is what most equipment shops use

I vote with drujinin, have a small area for a work shop with concrete that you can heat, infloor is great if you leave it on, otherwise wood heat or overhead radiant tube heaters are instant on/off, Crushed conccrete, gravel or limestone is far cheaper for the rest of the cold storage area. 1 more thing, I used a product called cure seal on the concret, is is applied as soon as the mason is done, it slows the cure to make it stronger and seals the surfas so you can wipe up oil with ease and makes it easier to sweep.
