The slab has been curing, and as we did a post-tension foundation, there has been tightening of cables over time. Thankfully it has rained since which is good for the slab (once it is sufficiently dried), keeping it hydrated and minimizing potential for cracking.
While we were playing with concrete, we might as well go ahead and put in the sidewalk and driveway. Week 3 gave us the most massive driveway - you could easily park 4 cars in the driveway alone - which for inner-loopers like us who have been fighting for parking for the last decade, that is like having a personal parking lot. And they don't even charge you $20 to self-park. Score.
