I am installing a shower stall in my basement. I broke up my foundation and have to move the existing drain.

First, am I supposed to fill the whole thing with concrete once the drain is in the proper location?

I see they have two types of drain assemblies at HD. One has a black rubber gasket that just friction fits over the drain pipe, the other is a PVC glue type. Which one should I use taking into account that this is being installed on my concrete foundation?

Thanks
