The next step is to prepare the buiding site for the slab. You must build concrete forms to give the concrete its shape, and also create a reinforcing mesh to protect the concrete from cracking appart.
The tools required for the job are: hammer, duplex nails, planks, rebar, bricks, wire, diagonal pliers, shovel, 2x4s, plastic sheeting, metal cutting blade for rebar, Tie wire tool, and sledge hammer.

- Making forms for the slab
Forms for a slab are perimeter constraints keeping the cement in place during the curing process. Forms give the slab its shape.
Select straight lumber with the width being 3" wider than the thickness of the slab.
Begin nailing the forms at one corner of the site using the markers already in place as a reference point.
If your board are not long enough to reach from one marker to the other, then join two together end for end with a scrap piece of board nailed on both ends as support. Be sure to use duplex nails as you will have to remove them carefully at a later time. Make sure the scrap lumber is nailed to the outside of the forms so as not to leave an imprint of it on the slab.
It is very important that all corners of the forms are square. This is accomplished in the same manner as
using equal diagonal measurements from each corner.
As can be seen in the image above, the sides must be kept straight by with 2x4 supports throughout, to prevent bowing.
Spread and tamp a 3" layer of granular fill. Measure down from a string stretched across the forms. Slope the fill down along the edges to create a thickened edge of concrete.
Next lay a moisture barrier for the bottom of the slab.
- Reinforcing the slab
Lay a grid of rebar spaced 4' appart onto the plastic accross the entire of the length of the slab.
Now intersecting the existing rebar at 90* lay rebar again 4' appart accross the entire width of the slab.
Place a brick under each point of intersection and at the ends of each length of rebar.
Connect intersections with tie wire to keep rebar in place
Divide the slab down the middle with a 2x4 nailed to 1x3 stakes. Align the top edge with a taut string.
