Answer 2

floating slab 4" thick. 1) establish your grade. 2) Set up your forms (2x4) 3) dig on the inside of forms along all edges down 16" and into the slab area 12" so you have a 16" deep by 12" wide trench around the inside of the forms 4) put your rebar in this trench on chairs.5) place 6x6 wire mesh over plastic on ground through out. also on chairs or small rocks will work too. 6) get short pieces of rebar say 12" long and pound them into the ground every 4' or so leaving 4" sticking up this will help you gauge the concrete as your spreading it. 7) you will need help so call on some friends 8) order you concrete with out heat and first thing in the morning otherwise it will set up so fast and if it is a late pour it will have been in the truck too long. order extra dont be cheap if you run out you will be sorry you footing trench will not be exactly 12x16 9) you will need some rakes and shovels or if you want to look good get a special tool called a come along looks like a backwards snow shovel for pulling concrete. Use a 2x4 (as others spread) to even the concret and get the butter up top as you work you'll understand butter. let it set up a little then using a gator-ade or other with a hole in the cap for a water squirt bottle. fresno it smooth or broom it if you prefer GOOD LUCK remember lots of helpers

Answer 3

You clean out the whole area. Square it up using string. Put down at least 2 inches of gravel, smoothing it out and making it as level as possible. Of course, once you string it making it square you need to put down forms that will hold everything in. If you use lumber, you can brush any type of oil on it so the forms will come off easier when the concrete sets. After the forms, gravel, and knowing it is square, you are ready for the concrete. This will require approx. 8-10 yards if you go 4 inches deep, which is usually the code.
