cost for concrete per yard
Poured Concrete Wall Costs. Concrete prices vary widely by region of the country and time of year. Ready-mixed concrete will cost between $65 and $90 per cubic yard (3'x3'x3'). To put this into perspective, a wall 9'x27'x12 thick would take 9 cubic feet of concrete. Building a concrete wall also requires reinforcing metal bar, or re-bar to help solidify the wall.
