It was 95 degrees here over the weekend and probably the same percentage of humidity. When I went to the Home depot to get a new digging tool their only advice was to find something else to do. It was really the wrong weekend for sure but the delivery is expected early this week and I wanted to have the hole ready.
The hole is supposed to be 2’ x 2’ by 3’ deep or below the frost line. Our frost line has been reported as 1 meter up to 40” . I found this map on line and this one as well which both seem to suggest that 36” will be safe. Just to be sure, I called our building department and they told me 42”. I am now really depressed and have a ton more digging to do.
I started digging Saturday morning using a post hole digging tool and a shovel. I ran into a bunch of rocks and went to the depot to get a 6’ pry bar. After that it was slow going, particularly as the hole got deeper without getting much wider. At this point I can only make progress by being in the hole and digging with a small shovel and a crow bar. The challenge now is to keep getting deeper without getting wider. The hole is already more than 2’ x 2’ and the wider I get the more concrete I am going to use. I am also working on belling out the bottom.
So now I need to lift the rock out of the bottom ( came from the side), go about 6” deeper and bell out the bottom. I then want to build a frame for the top so that I end up with a square pour. Lastly I am going to pull chalk lines from the house foundation so that the system will be exactly perpendicular to the house.
