We need to install a waste water supply line for the 14 floor building and it's each floor have 8 bathroom and 4 kitchen.
We have two option now one is solid pvc pipe and second one is Foam Core PVC pipe made as per ASTM f-891 schedule 40.

For something this size you should have a permit and plans. Check with local permitting office. BTW you made a statement not a question. Some local authorities do not allow foam core.
