With the sloping rear lot, we must excavate the garage pad much lower than grade in order to have a gentle apron on the garage to provide smooth access to cars, yet ensure the garage is well above the often wet and snow filled alley.
Generally in Calgary construction the garage is a four or possibly six inch thick slab poured basically right on the ground and it is subject to frost heaving and penetration by rain. Sometimes the edge is thickened to improve the structure, and rebar is added. In our case we have put in a new footing, similar to what would support a house, and an eight inch concrete perimeter wall. This should make for a far more robust garage structure.
