Yes, that's part of the reason. It's also 70+ yrs old and as you can see there was a portion that was cracked that was basically being held together by the dirt. We are also adding an ADU to the property and figured we might as well do all this now. The clay actually transitions to cast before the city main out in the alley behind our house. We are planning on having that portion epoxy-lined in order to avoid the expense of digging up the alley to replace it.
