• Measures differences between two subsequent 3D laser scans.

• Differences are shown with a color map.

• Calculates amount of shotcrete of a given thickness needed in a given area.

• Ideal for measuring thickness of sprayed   shotcrete.

• Instantly produces shotcrete spray audit report.

• Markers are used to automatically align the scans before and after shotcrete spray.

• Each scan takes only two minutes.

• No special alignment of the scanner is needed.

• Scanner can be placed at different locations for the two scans.

• Can also be used to measure rock-mass movements or for convergence measurements.

Step-1: Install system markers on any 3 – 4 points near where shotcrete is to be sprayed.

Step-2: Perform a two-minute 3D laser scan of the area with Versa3D. No need for any special alignment of the system.

Step-3: Software calculates the amount of shotcrete needed to cover the area with the given thickness.

Step-4: Spray shotcrete.

Step-5: Rescan the area with Versa3D.

Step-6: Software automatically aligns the two scans and shows the thickness of the sprayed shotcrete with different colors.
