Gabriel Stone, 14, from Warner Robins, Georgia, died on July 22 after the concrete wall at Robins Air Force Base's Heritage Club pool bathhouse collapsed on him and his three friends.

Oftentimes, when a retaining wall loses visual appeal, the easiest way designers and property owners use to restore its beauty is to scrub it, especially if it’s a concrete or stone wall.
