Introduction Underground infrastructure demands a precise balance between speed, safety, and structural integrity. Whether it's mining, tunneling, or underground utilities, the pressure to stabilize excavations and reinforce rock masses is immense. Two vital components in this process are cable grout and Tunnel Guard. When used effectively, these materials protect...
