Shotcrete machine is divided into wet mix shotcrete machine and dry mix shotcrete machine according to the different produce process.

For wet mix shotcrete machine, the spraying soil, cement, stone need first be mixed with water in the mixer, and then pure the mixing concrete into the hopper of shotcrete machine. While dry mix shotcrete machine, it add dry soil, cement, stone in the hopper of shotcrete machine, finally adding water in the nozzle.

Compared to dry mix shotcrete machine, wet mix shotcrete machine have more advantage, such as low rebound, low dust, having much higher strength.

For customers, low rebound can greatly save concrete materials; furthermore, it can give the customers more economic benefits. But for slope-protection, we recommend dry mix shotcrete machine for customers, which is more economic and efficient.

For slope-protection, if there are three words that we will describe what the geology engineering works are, it will be “Soil control and improvement”. Soil control refers to slope protection or stabilization. Others prefer to use the more graphic “erosion control”. These are the work or interventions that are done on a certain slope to prevent it from falling or sliding down (eroding). Examples are the application of shotcrete or concrete spray to the surface of the slope, and when needed, the installation of soil reinforcement, like soil nail and anchors to hold it in place. In some cases, planting vegetation (bioengineering) and just reducing the angle of the slope are effective slope protection methods.

Soil improvement refers to the modification of the soil properties itself. Examples are the application of cement grout to the ground to improve its bearing capacity and allow the construction of a structure. Grouting can be done in different ways depending on the desired soil improvement. Jet grouting improves a certain diameter of the soil, by mixing cement grout with the existing ground to make it stronger and able to carry the load of a building’s foundation, for example. Consolidation grouting binds highly fractured rock to prevent water inflow or outflow, to allow a tunnel construction or and excavation for a certain structure.
