A concrete sprayer machine, also known as a shotcrete or gunite machine, is designed to apply a mixture of concrete onto surfaces through a high-pressure spray system. The material is conveyed pneumatically and sprayed to create a uniform layer, often for structural support or surface finishing.
The machine is widely used in tunnel construction, mining, slope protection, building restoration, and more. Thanks to its automated operation and consistent output, it significantly reduces labor intensity while enhancing construction speed and quality. YG offers a variety of concrete spraying equipment built to handle both simple and demanding job sites, delivering outstanding performance across multiple industries.

Advantages of YG Mortar Spraying Machine
- Efficient and Time-Saving Construction
These machines can cover large surface areas in less time compared to manual application. A wet shotcrete machine, for example, features a large displacement design that allows fast and continuous delivery of material, which greatly reduces the overall construction timeline and labor costs. - Superior Construction Quality
With precise material control and uniform spray distribution, the machine produces a dense, well-adhered concrete layer. The output has low rebound and high bonding strength, which is crucial for structural integrity in tunnel linings, mining shafts, and retaining walls. - Flexible Adaptability to Complex Conditions
The design is compact and lightweight, ideal for maneuvering through narrow spaces and irregular surfaces. Whether operating underground or on steep slopes, it adapts easily to a variety of working environments. - User-Friendly and Low Maintenance
Many models, such as rotary sprayers, feature simple operation and maintenance. Some come equipped with intelligent features like blockage detection, which automatically stops the machine when necessary to prevent equipment damage and reduce downtime. - Environmentally Friendly
The wet shotcrete machine greatly reduces dust levels during operation, creating a safer and more environmentally friendly work area. This helps protect workers’ health and meets modern safety standards.


Applications of Concrete Sprayer Machines
- Construction and Building Engineering
These machines are widely used for wall rendering, crack repair, insulation layers, and waterproofing treatments. By spraying mortar or concrete uniformly, they enhance both the functionality and aesthetic of buildings. - Tunnel and Subway Projects
Tunnel lining and reinforcement are critical areas where spraying machines shine. They provide essential structural support and improve tunnel durability while preventing loose soil or rock from collapsing into the tunnel space. - Mining and Underground Engineering
In mines and shafts, spraying machines help stabilize the underground structure, reduce geological hazards, and support long-term excavation operations. A mortar spraying machine can also be applied for lining mine walls and sealing leakages. - Hydraulic and Infrastructure Works
For riverbanks, dams, and canals, this equipment assists in repairing erosion or structural damage. The even spray of concrete enhances water resistance and prevents further deterioration in hydraulic structures. - Additional Industrial Applications
The machines are also used in power plants, highway infrastructure, and prestressed engineering for injecting mortar or transporting fly ash slurry. Their flexibility makes them ideal for a wide range of industrial tasks.
