Spent the last two days paving.
The blocks are 2' by 2' by almost 2" thick. They're about 90 pounds apiece. We had to determine the elevation we wanted them set at, get sand, etc. The shed is at an angle relative to the wall we used as a reference point, so we had to cut a bunch of blocks there. We also had to raise the height of one of the sprinkler boxes, it looks like it had subsided somewhat since it was originally installed.
We had to grade some of the dirt, some was too high, a lot was too low. Also had to buy about a ton of sand in two trips.
Today was the second day, we had to cut around the sprinkler box, the conduit and copper tubing, and the curved front. That took a very, very long time. Ended up rough-cutting with a masonry blade in Dad's 7-1/4" circular saw and then using a 4" angle grinder to finish the curves.
