Questions about Mud Slabs
(OP)
It is recommended that mudslabs be used for blindside waterproofing under structural slabs. Besides providing a flat working surface, what other benefits do mud slabs provide? How do I determine whether it is really necessary.

there's been times where we ended up having to pull the mudmat back out before pouring because the excavation sat under water for a month (rained every other day and we didn't have enough time to tie all the rebar and didn't want to end up having to pull it all back out to clean off mud mat). that particular instance is the only one i can think of where the mud mat didn't work quite as we expected...however, we pulled the mud mat out plus maybe an inch of the underlying soil and everything else was good-to-go so the mudmat still performed well and was worth the minor expense). even if you drop a few hundred dollars on a mudmat for a sizable excavation, it's very quickly made up in the time spent by the workers waiting around to clean up the area and or additional undercutting that might be required due to softening of the surficial soils.
