High robotic arm wet shotcrete machine use for pumping concrete A high-reach robotic arm wet shotcrete machine with concrete pumping is a specialized piece of construction equipment that combines concrete pumping with an articulating robotic arm to spray (wet-mix) shotcrete onto large surfaces—especially in hard-to-reach areas. These systems are widely used in tunnels, underground works, slope stabilization, mining, and other geotechnical projects where precision, safety, and efficiency are crit
