Portable electric shotcrete machine

A portable shotcrete machine is a compact, mobile piece of equipment designed to pneumatically or mechanically project concrete or mortar at high velocity onto a surface. It’s widely used in construction, mining, tunneling, slope stabilization, and pool building due to its versatility and ability to apply material efficiently on vertical or overhead surfaces.

Types of shotcrete machines:
Dry-Mix Shotcrete Machine:
Mixes dry concrete/mortar with water at the nozzle during application.
Generates more dust but is cost-effective for small projects.
Wet-Mix Shotcrete Machine:
Pre-mixes concrete with water before pumping.
Less dust, higher strength, and better for large-scale projects (e.g., tunnels).
