Crack in new slab


I didn't mean to be wise ass, but I am lost too. What concrete underlay material reduces the weight of that poured on top of it? Am I missing something basic in the laws of physics and gravity in this?

Apparently, he needed the new slab to be 5" higher on average than the existing slab. Rather than pour it completely in concrete, he replaced 2" of concrete with a lighter material.

It reduces the weight by displacement. Less concrete=less weight.
