I'm going to be expanding up & out, instead of digging dirt out.
I need to know how to build a strong wall of cinder/concrete blocks. Want the walls 3ft to 3.5 feet above the ground. I'll be using an epdm liner.
Do I dig down a certain amount first, to the frost line? I'm in Virginia.
Use rebar in the ground & through the first one or two layers of blocks?
Does dirt or concrete fill these blocks? Or can solid concrete blocks be used instead?
Or does this need to be all poured concrete, then place the above ground block on top?
After the base layer of blocks, do I need to use solid concrete blocks for the rest of the wall height? Or can I use open blocks & fill with dirt?
