I'm building an Allan Block retaining wall and I'm trying to follow the manufacturers directions as closely as I can. It's going to replace a
30 year old railroad tie wall that was secured by rebar driven 6 feet into the ground. I have removed the old wall and have the block and gravel on site. But I have never used a plate compactor. I had dug the old wall back just enough to allow me to backfill with 12 inches of gravel and then compact it. I see now that any plate compactor I can rent will need more than 12 inches to operate. I'm leaning towards digging back a few more inches, renting a reversible plate compactor, and seeing how that goes. But it has also been suggested that I might get away with using a jumping jack for compaction - much lighter to move up on each 8 inch course and also narrower. But the description of how the thing jumps around is putting me off. Any thoughts from anyone who has used either device would be appreciated!- posted
