Shotcrete
Shotcrete is all about projecting a mixture of cement, sand, and water through a pressure hose, producing a dense hard layer of concrete used in building for lining tunnels and structural repairs.
This method is preferable because of two main reasons:
- less thickness and bigger resistance
- quick setting
In addition, shotcrete adapts to the surface it's projected.
Result: Lower cost of production
Grouting
Grout is a material generally made out of water, cement, and sand. It is typically used for filling voids in tunnels or other structural elements, sealing joints and openings in surfaces and reinforcing existing structures.

The grouted surface has an increased strength, stiffness, and reduced permeability.
Result: the lifespan of a tunnel increases.
Bolting
Construction bolts are made to exceptionally tough standards to support high-demand structural applications. These include buildings, bridge, tunnel, highway, pier and marine, and other forms of infrastructure.

This method is commonly used with shotcrete to reinforce tunnels.
Result: high strength.
