I want to level some ground on the far end of my driveway to use as extra parking - it would involve adding fill to level a space about 12 x 16 feet. The most fill would be two feet worth at the far end along the property line chain-link fence. I figure on building a retaining wall along the fence line from standard concrete blocks, the base of which would step down in one-course increments as the slope drops.
I was advised on a way to build the wall that involves dry-stacking the blocks, driving rebar down into the grade thru the block cavities, then filling the cavities with cement, which I would also use to cap off the wall. I'm thinking of using gravel for footings, mostly so I could drive the rebar through it. I reckon on sloping the grade down past the end of the level area if I need to wheel anything down to the backyard.
So does this seem like a sound way to do it? I'm figuring on using cement block rubble and dirt for the fill - that I'm getting from pulling out a low retaining wall further up the driveway as old as the house (55 years) and falling apart at its mortar joins (I'm cutting out a sloped bank where the wall was). Hopefully the new wall will hold out better than the old one.
