Garage backfill

[JimL]

Time to backfill the inside and outside of my garage. What size stone should I use? I don't want pea gravel. I've had a couple people tell me to have 2's shot into it. 2" crushed limestone. I need quite a bit...

Well ****. It's sideways.

I had less to backfill but I used 1" crushed granite, compacted with a plate compactor then put down a layer of process that compacted beautifully.

3/4 process compacted in 4" lifts. If you have a pool water guy nearby leave the last 4" out and have him flood it with 6000 gal then compact. add last 4" of 3/4 crushed stone or 3/4 process and you will have one rock solid base. I used 8 tri-axle to fill in mine. Your garage is identical to what I just did (I cut my side door in after)

Cool. Ordered 3:4 process.

I used 3/4" crushed ledge stone. It is 90% compacted as it falls off the truck. I still compacted with the bucket of the excavator as I spread it out. It worked very well.

sand, sand clay

Recycled crushed concrete. It has lots of fines in it and when compacted it is like concrete.

What size is that in your area ?

Names for aggregate seem regional. 3/4 process is essentially crusher run, 46D, #411, 3/4 minus, etc consist of crushed stone and concrete 3/4" with fines down to the size of dust.

I would suggest backfilling with fill sand, then a 8" final layer of aggregate (we used 1" minus crushed concrete). Pit run Sandy loam is what we use(compacts nice). Pack it in lifts no deeper than a foot thick. The flood it idea works great! Put the aggregate down, pack it, wet it some, pack it some more. Let it set, pack it again! Grade it out as smooth as possible to maintain a consistent thickness of poured concrete. Standard is 4" thick here, we go 5" to be safe. Most all cheapskate contractors here pour on fill dirt the whole thickness... This is cheaper, but yields a weak stability to pour on. I don't like pouring on only fill sand. Sorry. I've worked Excavating my whole life, so I am speaking from experience. My 2cents...
