Foundation Slab

It was an exciting time at the site on Thursday! Starting at 8:30am, I got to see four large cement trucks navigate the narrow streets into my driveway to pour out the slab for the foundation.

The pour begins:

There's no turning back now! We can't even drill into the concrete after it has set because it would risk puncturing the embedded piping. Also of note in that picture is the 40ft coil of copper wire (lower right) leading to a Ufer ground setup in the foundation. That'll hook into the electrical box of the house. Here you can see the contractor directing concrete from the tube in the sky:

At the recommendation of the architect, we had "Seattle Sidewalk" pigment added to the mix to darken the slab. He said that concrete color matching is an inexact science, and he's had good results with that color in the past. It looks good in the photos!

Once the last concrete truck drove away, the troweling process began:

I was told they were out there until around 6pm. I can't wait to see what it looks like after it has cured! Next up are the retaining walls for the foundation.
