    When pools go bad....

    Here are some interesting case studies of bad things happening to pools.

    BAD BENCHMARKS
    For years, says structural engineer Ron Lacher, pool builders have experienced failures of steps and benches in their
    shotcrete swimming pools 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 he has responded with a detailed investigation of the problem’s
    possible causes—and a simple, workmanship-based solution offered herein.

    I wish I had a picture of my previous spa to show the PebbleTec that fell off the side.
    It was about 2 ft x 4 ft and went almost the entire side. It was repaired, but when I sold the
    house I noticed that it was cracking again.
