I replaced a section of 3" ABS with two PVC 3x2 wye's under my slab. The side of the pipe closest to the outside of the house actually has much of an old hub and ABS encased in the footer of the house. While I was digging this up near the footer I found the dirt to be very slightly moist vs the extremely dry clay everywhere else. After my modifications were complete with everything still dug out I found water leaking out of the meeting point of the bottom of the ABS and the concrete footer. Looking with an inspection camera, there is a section of 3" ABS (encased in concrete) right past the hub that is cracked. It's about 14" from the outside and a really hard reach of 8" from the inside. What is the best way to approach this?
I have considered trying to dry it out and drilling some holes in the slab and fill around the pipe with closed cell expanding foam, or maybe cutting my new section out hoping my hand can reach it (20% chance) and using epoxy to fill the crack, or maybe contract someone to line that section of pipe with epoxy (although not sure if being that close to a wye is great as it is pretty close). Any thought or suggestions would be appreciated.
