I live in a ranch with a concrete slab for a foundation built in 1956. The kitchen drain feeds into the pipe under the concrete where it is rotted or collapsed. This 2 inch pipe runs approx 18 feet to the main drain out in the center of the house.
Since I know I will need to cut the concrete and dig the old out to replace it, I need to know what kind of connectors should I use to connect an 10ft and 8ft piece together. I just don't think the rubber seal with clamps are the correct type for underground use. Any Ideas on what is?
Thanks for any assistance provided

You should use plastic (ABS) for any replacement runs if possible. Yes you can use clamp couplings underground (for iron-to-iron and iron-to-plastic connections) but not just any type. You need heavy duty clamps listed for that service (not cheap "no-hubs" from the ubiquitous orange big box). We call them "mission bands" but that is a brand name (no endorsement) that has become a common moniker. Of course, you should check with your local code enforcement authority.
