Lift for storing stuff above the fridge

Since you say you have a ceiling system and no direct rain in this protected area, I would think you want a material that will pack down firmly so wheels of equipment and walking won't depress into the material too much. I have used 3/8" stone dust, which is a by-product of the stone crushing process mixed with 3/8" pea stone. This material is heavy, forms grade and packs well. You could also use a clean "packing gravel" which is a very coarse sand used under concrete slabs etc. Another good solution is to use a garage mat over the base to park heavy objects on. These mats are available at many box stores and auto supply places. Another good reason to use a parking mat is that oil or fuel spills can be cleaned up before they seep into the soil. You can also sweep it clean occasionally so it looks neat as well. Good Luck

Building code requirements normally require a minimum of around 30-40 pounds per square foot of live loading capacity for standard residential floors. Assuming they are stacked and laid flat (and the floor was built to code), a 4' by 8' section of floor should be designed bear somewhere between roughly 1000 to 1300 lbs of live loading. Note that this is both the minimum and the average for a uniformly distributed load, so the bearing capacity along the walls will typically be substantially high.

That said - if you have the space, divide it into multiple stacks. 2352 lbs. comes out to 73.5 pounds per square foot. I'll usually stack them up standing against the walls in the rooms they'll be installed in. Less carrying sheets around when you're hanging it, and unless the room is enormous you don't end up with huge piles anywhere.
