The MAS™ system uses shotcrete and due to the application in layers, shotcrete does not have cold joints. Shotcrete creates a much stronger bond and because of the consolidation during the application process and the resulting strength, cracks are unusual. Any cracks over time would be superficial and not structural. MAS™ guarantees this!
Most users texture the concrete with stamping and thus the graying effect is minimized. Also, the use of color in the final 1/4″ to 1/2″ layer is very inexpensive and will eliminate the “gray” concrete look if objectionable. Many users also elect to stain the concrete using various colors to achieve the architectural look desired.
