Shotcrete 101

This is a example of a qualification panel showing a nozzleman placing wetmix shotcrete using the bench method. After creating the bench ( approx 45 degree angle) The idea is to place the next layers perpendicular to the previous placed materials minimizing skipping and rolling. Notice the Nozzle man changing the distance and the angles to maintain a good recieving surface. Material does not build up on the front of the bars but wraps around building up from behind. the deformations on the bars remain visible until they are encased.
