Q: What is the estimated cost per square yard of sandblashng a continuous exterior concrete wall when the total area is about 5,000 square yards?
A: The estimated ranges of costs per square yard for sandblasting are:
Brush blast (1/32 inch deep)
Light blast (1/16 inch deep)
Medium blast (1/4 inch deep)
Heavy blast (3/8 inch deep or more)
If all other factors are favorable, presumably the cost range would be toward the lower end of the scale on a 5,000 square-yard job.
