We are building a home where some of the outside walls are bricked. Is there a way to use shotcrete over strand board ? What cost would there be a square foot for the actual shotcrete installed?

More information is needed before answering this correctly. Shotcrete will stick to strand board, but you need some type of reinforcement (wire mesh) to hold it all together. A good cement plaster mix at a lower velocity would be more economical. Contractors who have shotcreted a house in the past will tell you that it is too time consuming for the money involved.
