Despite the temptation to reuse rebound to reduce shotcrete installation costs, doing so is always the wrong choice.
Proper shotcrete application naturally generates rebound, just don’t be tempted to use it.
It’s one of the cardinal sins of pool construction - reusing rebound has been debunked, discredited, and discarded, and should be forever forgotten. Anyone still maintaining this practice is in direct violation of shotcrete workmanship standards and is, I believe, operating on a dangerously subprofessional level. As my friend Paolo Benedetti says, “‘Shovelcrete’ is completely unacceptable!”

The good news is, I think it’s fair to say that the industry is using less and less of it. For the past 20 years at least, in magazines like AQUA as well as in classes taught by reputable experts such as Watershapes University, and certainly in publications promulgated by the American Shotcrete Association and American Concrete Institute, the standards have been made clear. All have been pounding this drum and the message is just don’t do it!
