Sub-Slab insulation and a Basement Floor

Again, these pics load with a mind of their own, so this time they are in reverse order - oldest at the bottom.
Above you can see the finished basement floor that was poured today. The pic below shows the concrete beginning to be pumped in.
The two pics below shows the very important Insul-Tarp product laid out. This insulation provides a barrier below the basement slab and an R-Value of approximately R-10. You probably can't see from these pics, but another important detail is the spray-foam insulation that the contractor sprayed between the footing and the ICF form.


Before the Insul-Tarp was laid, we also had the site treated for pests - which is a requirement here.
