Pour concrete small retaining wall rebar form.
As a minimum 4 rebar 1 2 inch is spaced vertically at 36 inches on center continued to within 8 inches of the top of the wall placed on the tension side the inside face of the wall.
Add rebar for reinforcement ralston places rebar every 16 on center.
Thus good placement of horizontal and vertical rebars in a footing is of utmost importance as placing concrete.
Prior to wetting the concrete you can easily drive rebar into the bags as reinforcement.
Pour and level the concrete.
Concrete weighs more than water and it will displace the water when introduced into any container or form rather than mixing with that water.

Free standing poured concrete non reinforced dome.
Just placing stakes on the form will not hold instead you must place kickers on the wall to hold the form.
The placement size cover tying and tolerance in steel reinforcement are considered to achieve ultimate efficiency of the footing.
A little reference for you all.
Pour footings and wall.
Have a helper add or remove concrete in front of the screed as you pull it.
Once the truck has reached the end of a section spread the concrete out evenly and a touch higher than the form with a concrete placer rake.

Pour your footing first placing re bar vertical stubbed out of footer and wait at least a day for the concrete to harden.
Contents placement of rebar in footings1.
Pour in sections pour the concrete in small sections spreading the concrete by moving the chute back and forth and by having the driver pull forward as you go.
Pour the retaining wall roll the wheelbarrow of cement over to your wooden forms and pour the cement into the footing and form area.
Once the forms are full of cement you can smooth out the top of the wall.
Drag a straight 2x4 screed board across the top of the concrete forms to level the concrete.
If the wall exceeds four feet in height footings should be poured separately.
