I am going to pour an 8" deep x 16" wide concrete footing under the frost line (4' down), with a block wall on top of it going up to grade. The soil is very heavy, solid, red clay. Do I need to have aggregate under this foundation for drainage, or can I pour the cement directly onto the soil? Usually, I believe 6" of stone is recommmended, but is it necessary for an oven footing this deep, in clay? The bottom of the footing will be 54" below grade, if that matters.
And ... is there any reason not to use standard ready-to-use Quikrete for this footing?
