I have foundation problems. I have these steps that have to be removed to fix it. The steps are 5' 6" wide and 42 inches high. They are poured concrete. I need some ideas about how to remove them. The wall behind the steps is leaning in. I do not want to make it fall, it is a basement wall. I can't get a strap or chain around the top because the top of the steps are leaning in on the bricks.
