John McEwen had a good article on waterproofing n backfilling with most-all gravel and so did Yoder builders in Ohio, both not available these days
Personally, throughout 4 decades of doing this shtt, we have always backfilled with most-all gravel, had all the clay and other junk that the builder backfilled with hauled away. Other junk includes wood, fairly often big g dang pieces of wood, cans, blocks, bricks and so on - all lazy stupid shtt, they didn’t care about what-how they backfilled, most still don’t.
Have gone back many times n looked at almost all these houses we backfilled with all gravel, ZERO problems with any supposed settling or other crap some bring up, NOTTA ONE.
Don’t want water sitting against the walls, the cracks, the bowed in walls, want to reduce the pressure hence the gravel backfill.
What works better above? We put top soil on top of a smidgen of clay or silt etc on top so homeowner can put flowers etc back if they choose, not on drive side walls or where concrete or pavers are going back in, all gravel then.
Wish i’d had taken a video on one of last estimates i did in Grosse Pointe Farms, a landscaper put in 4 shallow exterior french FRY drains in backyard and on one side of house, homeowners are getting water in basement and too much water puddling in some areas in B-yard, thing is the landscaper tied all 4 ext drains into a pvc pipe that goes through the block basement wall below grade and then under the basement floor lollll, got it? UNREAL! Who brings water, that amount of water INTO a house, into a basement n under the B floor, shhesh, tell ya who, an incompetent moron does this shtt, maybe Bobber in CA-land too, dunno, he may chime in, the landscaper prolly writes better than Bubba and so duh Bobster would likely agree with what the knothead did
