On Friday, the workers sealed the concrete. The sealant certainly is a vibrant color!
The big cement mixer came today! The workers divided their day between cutting the driveway (presumably for drain pipes) and pouring the footings/foundations.
There was more cutting and digging. Today involved drain pipes, vents, cleanouts, and getting the footings ready for inspection and approval by the structural engineers.
