Here are the options from best to worst.
- 1. Gravel with drain tile and drainage pipe away from house
- 2. Backfill with clay
- 3. Backfill with gravel without drain tile and drainage pipe
Additionally, I could apply a non-permeable membrane over the backfill to shed water away from the house. This membrane could be used with either of the 3 options above.
I don't think there's much question about which solution would do the best job. What I see as the question that needs to be answered is "How good is good enough?" Building a house is filled with decisions regarding money, time, effort, and trouble. If I chose the idealistic option for every issue, this house would cost a million dollars to build and would take forever to finish.
For me, Option 3 is out of the question because like Pops and Eddie mentioned, it will keep the footers wet. My guess is that it would be extremely rare in my area to find a house built by a GC that uses Option 1 around the main floor garage or the main floor of a house without a basement unless the grade of the lot runs toward that part of the house. And I'd be surprised if 1 out of 100 houses in this area have a membrane installed on grade around the house.
The question cannot be reasonably answered without considering the natural grade of the land where the house sits. The house sits along a ridge line. The natural grade steeply slopes away from the house in almost every direction. The house is naturally protected from water.

You're right. Building a house is full of decisions. Nearly all of those decisions will involve a compromise of some sort. Clay is "good enough" for backfilling around your garage given the lay of the land. If you were talking about a basement at the bottom of the slope then we'd be looking for a better solution.
