Gravel Compaction under Conc Slab Floor
I would suggest using a plate tamper here you can rent one fairly cheap. Compact in layers(lifts) no greater than 2-4".
=====
The problem I've run into with renting A plate tamper is the time spread required to compact in layers / lifts.
Makes the rental of the tamper to expensive to keep around for so long.

Gravel Compaction under Conc Slab Floor
Macdaddy:
Having been from WNY Lockport - where GM left Harrison (
1. ensure no groundwater runs below your polebarn structure by addressing grading outside the structure;
2. add a few drains - say bed ~ 4' below grade and day-light outside structure;
3. add poly membrane below slab to prevent vapor migration (if you intend to enclose & heat in the future);
3a. provide crushed stone for concrete water a place to go.
4. rent heavy "walk-behind" roller - don't go crazy on the vibratory on the subgrade- especially if you have a saturated silty clay / sand soil.
5. ask your concrete supplier about fiber-reinforcement vs. steel mesh - be advised it ain't easy to remove though;
5a. ideal temp is 50 deg & rainy weather -ifff subgrade is compact and firm;
6. try Journal of Light Construction - jlconline.com ? for addt'l input.

Gravel Compaction under Conc Slab Floor
McDaddy,
obviously there's no foundation in your plans. Is this going to be a pole building with the posts in the ground, or just a floating slab with walls/entire structure/ on the top of the slab? Just like a reg. garage construction.
