Backyard ob pier slab specs?
Heya guys I'am looking at doing a backyard pier for ap work. I later plan to build an ob around this when funds permit. I have gone over a large lot of styles and design specs, what has me stupped as the ground block and what works best. I have herd of people using a full m^3 sized block but to me this seems stupid due to soil change, settling and the fact its going to sink unless your living on rock. So what specs are you guys using for your backyard ob pier slab base, for something thats going to have a eq6 with a 10 newt and your ap gear? BTW i'am talking about just the pier base/slab not a ob slab, I plan to isolate the ob foundations a good 1 meter away from the pier base/slab.
