A storm took down a retaining wall. Construction was concrete masonry blocks, cores were not filled. No Rebar or reinforcing mesh. Hard to believe that it stood for 40 years given that there was no footer under it!
The wall was 35′ long and 4′ high tapering to 3′ at the other end. Built of block that was 16″ deep for the first couple of courses, transitioning to 12″ block and then transitioning to 8″ block plus a couple of courses of brick.
Going to be replacing it with a dry stack block so I’ll probably end up with some excess gravel as well.
Anybody want to hazard a guess on how big a dumpster I need for this? Picture below
Thanks, Carlos

Craigslist it
Those blocks will disappear for free.

Absolutely, ditch fill, rip rap for ponds, streams etc. Ask a farmer or two. No sense paying for it.
In the right location I could see repurposing those blocks as you suggest, but in the suburbs they're not going anywhere on their own and I have no place that I can put them.
So I go back to my question -- how big a dumpster?
Thanks, CB
L x W x H /27 = cubic yard
30' x 1.3' max width x 4' max height / 27 = 5.77
so less than 6 cubic yards with throwing away all the air. Break them up and you need very little space. but the reality is who doesn't have other stuff to pitch?
If you (the OP) stack them in the dumpster you can get close to optimal packing (ie, 6 CU), but thrown in randomly I'd guess you have to increase the estimate 50-100%.
Excess gravel, if you put it in last, will fill the voids and add zero to the volume.
Be sure to talk to the dumpster people (in advance) on two points:
1) In some areas there will be an up-charge for the extra weight of concrete vs standard construction debris.
2) In some areas there will be a discount if you keep all other trash out (since the material can be crushed and reused for aggregate vs going into a landfill).
10 yards should do it.

Yeah, but why do you need two of them?
Thank you all

One for the gravel
Yes, i learned that I could put brick and block but not gravel in the dumpster if I wanted to keep the disposal fee down. We were able to spread the excess gravel in the space between my detached garage and my neighbor's fence where it helps to control drainage. Glad I learned here that a clean brick and block load was cheaper to dump than a mixed load. Saved me a few hundred $$
Thanks again
