Im rebuilding a retaining wall because it's leaning and bowing. I don't think a French drain was installed so I will be adding one. During disassembly I'm finding layers of different stone. The retaining wall blocks were filled with coarse stone. Then behind the wall and under the top soil is a 6" or so layer of mixed coarse gravel and soil. Below that is some chipped stone that looks to go all the way down to the foundation. My question is when rebuilding the wall with the French drain, should I use the clean coarse gravel that was used to fill the blocks as the primary back fill over the drain and use the fine chip stone to fill the blocks? Or would it be okay to just reuse them where they were?
