Level Slab on a slope.

My yard slopes. I want to make a 12x12 concrete slab for a shed. Rather than dig down to level the earth I would like to build a retaining wall and fill it in with dirt to provide a level spot for a slab. Any suggestions on how to do this and minimize the chance of the slab cracking?

Thanks for any help.

pour a footing around the area you are planning on building on. you will need to make it at least 12 x 12 in. then after making sure you have no weeds or grass growing in the middle fill it with construction sand and water as you are filling. fill in 3 in increments and water to settle the sand, if you really want it packed good run over with a vibirator to pack each lift. then water and add the next lift. vibrate and so on to the desired height. place a vapor barrier under the slab and use pieces of brick or pavers to support a wire mesh about 8 x 8 should work for that size of slab. that will help to control cracking.
good luck
