Ready to Pour

So we have torn down the fence. Then we dug a trench. It is 30" deep, below the frost line here in Kentucky.  The wall is 8''wide,  so the trench is 16", twice as wide. There is reinforcement steel at the bottom to hold the concrete together. Now we are ready to pour a base (footer 8' thick). By the way it was a lot of work to dig a 17' trench by hand. We carried the dirt away in buckets.
