(OP)
For drains where there are pvc tube inside concrete.. what do you use for waterproofing to ensure water won't enter the sides (in between the pipe and concrete)? We usually use asphalt membrane enclosing the tube end on surface of drain but we can't use it in a particular case. Is there some kind of bonding or waterproof liquid you can put around the drain so water won't seep in the perimeter?

In my country. All use torch-on sheet waterproofing membrane like in

This is expensive, and most said this is the only way to enclose the drain hole like in the picture above. Do you use this too? Why not? and besides cutting a reglet beside the drain to put sealant (can you do this after the pvc pipe is in place.. won't this chiseling the reglet crack the plastic pipe?) What other techniques do you use to ensure water won't seep in the perimeter in between the pipe and the concrete around it?
Thank you.

No. It's a bathroom in the 2nd floor of a residential house. Is it a requirement to use some type of membrane over the entire shower area.. or can you use waterproofing paint (including filling the perimeter between drain and concrete)?
The pipe is just cut at the end coinciding with the top of the concrete.. no flange or screws of whatever.
What do you guys use?

Why do you need to put membrane if you can totally seal the perimeter between the cut pipe and concrete by some kind of sealant?
