I want to get some feedback on what you guys would do. Here I have a client who wants garage to be raised to alley level in order to not have a steep slope into garage. Currently the grade of their backyard is about 4′ lower than their alley.
I’m thinking of using concrete blocks as the foundation, bring that up to 4-5 feet or whatever is necessary to create a proper pitch to drain water away from garage, once block perimeter is built, bring in soil, compact, class 5, then pour the 4″ thick slab.
What do you guys think?
