Progression of Work after Shotcrete Application
Because of its role in the concrete construction industry, the American Shotcrete Association (ASA) receives many questions both technical and nontechnical, from thoese interested in the shotcrete process.

Bad Benchmarks
For years pool builders have experienced failures of steps and benches in their concrete water-shapes much too frequently. What’s been puzzling is that the majority of these failures have occurred in spa steps and benches – a mystery to which we have responded with a detailed investigation of the problem’s possible causes, and a simple, workman ship-based solution.
