Ready to Pour Basement Slab

Due to the Labor Day weekend, we are just getting started again -- we will have the basement slab poured Thursday morning, and we're going to use it as a test slab for color.  We went to Ohio Ready Mix, and decided on two tones of brown (light and dark).  We'll have the concrete colored using the light color, and then we'll have a bag of the dark color (should be a chocolate brown) to throw out across the slab after they screed and before bull floating...

Here are some pictures of the stone in place -- there is also a sump pit in place (not visible in these pictures)...
