Cement floor about to be poured

We've leveled out the compacted sand/soil, then out down thick poly as a vapour barrier (taping the overlapping sheets of poly together using some blue tuck tape that is specific for vapour barrier and can get wet but still stays sticky), then put down on top of that a layer of dense rigid foam insulation from Greenstone Structural Solutions, a Canadian manufacturer that makes construction materials, with focus on green composite technology. The insulation is too dense for rodents to chew through, and higher R value than stuff on the market that is 3 times thicker (this stuff is 4 inches thick). On top of all that, there's a grid of rebar for structural support for the concrete that will be poured.

Back left pipe is for kitchen sink, middle right pipe is for toilet, front left pipe is for bathroom sink. Wrapped in the thin foil insulation a few times to give some protection/separation between the pipes and the concrete.

Concrete truck is here. Trying to keep out of their way.
