Stone Wall Panels – Now use the same size rebar, set the horizontal bar starting three inches from the top of the footpath and place one every twelve inches that lined the new wall with full length. Do this in both lines of lowercase. This, when finished, is called a wall mat. Using some small pieces of rebar, tie them with a wire between two mats to keep them inseparable as you pour the heavy concrete. The thickness of the new wall will depend on how thick your stone wall is and how badly bent the stone wall. My last wall is basically twenty-four inches thick but twelve inches thick is the minimum you have to wake up.
Layers of rebar walls you want to be as close as possible to three inches from both walls as often as possible. The inner mat may be slightly more dependent on the number of arcs in the stone wall. I use Symonds concrete form panels from my rented store to make it easy to build new walls but you can also build shapes of wood. The advantages of concrete form panels are they are present in all sizes with height and width, have clips for easy binding, have pre-made anchors and so on. You must remember that this is a one-sided form. The heaviest type so far to be built. You have to pin it to death and then add some braces to keep it from moving under the weight of wet concrete.
Installing what is called a whaler brace will keep the shape from bending but adds a lot of kickers. On a concrete day, you need additional help. Pouring through the basement window is not a joke because the people inside cannot see the man outside in a ready-made truck. A man must stay outside and shout orders through the window. Faster, slower, more too wet and so on. Since one person does nothing except seeing the shape. If anyone moves he should immediately stop pouring. Buried beneath wet concrete panels and ruptured shapes are not a joke.
Others should vibrate the shape with a mechanical vibrator to make sure there is no void in the concrete. But other people can tap the shape with a hammer to make sure there is a concrete in all the spaces and look down through the top of the form to make sure they fill the level as possible. It removes too much pressure in one place from one form at a time. Excess pressure can cause the form to fail. Wet concrete uses a sideways hydraulic pressure to the work form and can add pressure. I have seen a failed form that is blown a hundred feet from the workplace.
