I build on 57's and backfill with them also. Any open core block should be filled with a drain stone.

You can build on #57. You can also build on ABC/Crusher run. The only difference is with ABC/crusher run there is no drain pipe in the base itself.

Okey, I mainly use 57's which is around a 3/4 stone for my base. I have at times used crusher run all depending on situation. I have walls 10 years old and no problem. It is even accepted by NCMA standards. In my area we have a lot of solid rock and hard shale giving a strong base so we just add 8" of 57's level and build. Its not going any where, if we hit clay and go deep for soild ground than we will go with crusher run, compacted in neeeded lifts. Then i will still and a small amount of 57's to level and than build. And yes all 57's pipe goes on bottom , crusher run pipe goes on top.

i would recommend using crushed stone. Crushed stone means either 34- or 34clear. If you use clear it may require less in delivery fees. Also less trips if you have to haul the rock back off site.

It is less because then you only have 1 type of rock on site. Not 2 different types.

? for you. Do you use ab? I left them this summer after using the product for over 10 years due to they went to a 12" cap. It looks like sh*t on a 18" block. Are you aware of that if your not using there product on a regular bases. They still costs the same also 6" shorter. You cant even get a nice bomd on a straight wall.
