A driveway, house stem wall and slab need reinforcing, yes. But if you lay a sidewalk with rebar in it, that's a waste of money. ALL concrete cracks. Saw cuts are for controlling the cracks. A propane tank isn't heavy enough to justify reinforcement but it's also small enough that it would cost much to put wire mesh in. I'd just put down 3" of sand and concrete. The sub base has more to do with not cracking than reinforcing unless your building for a 5000 lb dead load on top. 3500 psi concrete on top of a sand base is very stout depending on the dead load afterwards.</p></blockquote><p></p>
