Raising Basement Floor Drain to new floor level.

Hi,
I'm about to flatten my basement floor which has a significant slope at the drain. I will be keeping the drain but need to raise it about 2 1/2" inches to meet the new level. However upon inspection I noticed that it is just a 4" hole in the concrete that leads to a clay pipe/elbow. The slab is roughly 5" thick at this point and there is also a strange 3/4" plastic pipe that goes under the slab and into this drain from a nearby sink drain.
What are my options? Do I have to smash up the concrete and convert from clay to ABS/PVC with a fernco coupler or can I just simply insert a 4" pipe into the clay hub?

Depends is it damaged it would be better to replace but that depends on your budget

The clay pipe is not damaged. Is there a way to sleeve a pvc/abs pipe into the clay?

To do it right, yes, you need to break up the concrete and run new drainage.
Best of luck....

If that and pipe is going to the clay pipe you need to place it all with abs
Only if it's sanitary drainage clay pipe is for storm water

It is storm water drain. I was hoping to just sleeve the concrete with an abs pipe and cap with drain cover.

Did you ever figure this out I'm about to do the same thing I have the same slope in my laundry room I just framed . I was going to leave it but the slope is too much that it's going to effect the doors I'm going to hang and the vinyl floor . was going to cut a piece of abs fit is in the hole . Poor my concrete leveler and use a drain cap ontop

Yes I decided to just sleeve the 4" clay pipe with a 3" abs which was a perfect fit. I poured self leveling concrete around the 3" abs. Attached pic is before self leveling was applied.
