Prepping Basement for Concrete Slab

This week has been spent getting the basement ready for pouring the concrete slab.

The bottom layers (which can no longer be seen) include several inches of gravel and the under-floor sewer plumbing. You can see the white PVC sewer drain feeders sticking up vertically out of the floor. These layers were then covered with a vapor barrier, several inches of styrofoam, a gridwork of rebar, and finally the hot water tubing loops for the underfloor radiant heating.

In this shot, you get a better view of all the underfloor water tubes feeding up into the utility room. To the left of the photo is the area blocked off for the elevator pit.
