The reinforcement schedule

If the basement is going to be habitable space

What are footings?

A shallow foundation that distributes loads from the structure directly to the ground beneath

Poured concrete that sits on top of pilings and piers

A deep foundation which uses a tall cylinder of strong material to distribute loads deep into the ground

A type of foundation formed by digging several round holes, adding rebar and filling with concrete

What are concrete piers?
