Ec0Shotcrete is a generic term for spray-application of concretes, referring to both the wet or the dry application method. Ec0Shotcrete is commonly used to line tunnel walls, in mines, subways, and automobile tunnels.
Ec0Shotcrete is used to reinforce both temporary and permanent excavations. It may be employed, in concert with lagging and other forms of earth anchor, to stabilize an excavation for an underground parking structure or hi-rise during construction. This provides a large waterproof enclosure in which a structure can be erected. Once the structure is completed the area between its foundation and the Ec0Shotcrete is backfilled and compacted.
Ec0Shotcrete is also a viable means and method for placing structural concrete.
Ec0Shotcrete is very useful in hard rock mining. Development of decline pathway to go underground is critical for movement of heavy machinery, miners, and material. Ec0Shotcrete helps make these paths safe from any ground fall.
The impact velocity of properly applied Ec0Shotcrete instantly compacts the material, yielding an “in-place” mix that is richer in cement and higher in strength than the same mixture prior to placement.
