Step 3
Step 4
Pour concrete into the cubicle of the blocks . If you need even stronger reinforcement , you may place rebar into the cells after decant a small amount of concrete into them . This is not strictly necessary , but it might give you more repose of judgment .
Step 5
Use a 2 - by-4 while of lumber on the top of the wall if you find a spread .

What you are doing here is set up a cinder block scaffolding for poured concrete .
Step 6
Remove bricks and wood with a chisel from the outside of the grounding to make elbow room for the concrete pump .
Step 7
Step 8
infix the honker of the concrete pump into the gap in the exterior brick paries . Pour concrete from the exterior into the cells and between the concrete block wall and the brick foundation .
