How to cut through a concrete wall.
Anyway the landord was adding an overhead door for the next tenant and the concrete cutters came in one morning anchored tracks to the wall and ran the rail saws in about 8 hours they had a 12 ft overhead door cut but like above left the concrete in the hole.
A huge water cooled cutting saw attaches to each rail and is slowly moved up and down the rails.
Score the length of the cut three or four times with the chisel.
If your cut doesn t need to be exact use a cold chisel and hand sledge to cut the concrete.
A circular saw with a masonry blade can also be used to either score or completely cut through the block.
Slowly guide the blade along the line until you get to a corner.
Line up the blade of a concrete saw over the marks on one side of the wall.

If you are going to cut a hole or drill through a concrete wall use the right tools to reduce the chance of damage to the wall.
Remove the saw blade and start in the other direction following the same procedure.
When you re cutting concrete that is already poured and finished use a chalk line to mark the region.
Turn on the saw and slowly guide the blade into the concrete.
Start at the top of the opening and cut carefully along the lines you made on the wall.
