Summary
Specialized construction work that injects cement-based or chemical grout materials into cracks and voids in concrete structures or ground to fill, waterproof, and reinforce.
Description
Grouting workers are specialists who inject grout materials using cement-based or chemical agents into cracks or voids in concrete structures such as tunnels, dams, and bridges, or in the ground, to fill, waterproof, and reinforce them. They handle on-site drilling and excavation, operation of injection pumps, pressure management, material mixing, and post-construction quality inspections to ensure safety and durability. They adjust injection pressure, flow rate, and viscosity according to the conditions of the ground or structure, and precise work based on construction plans is required.
Future Outlook
With the demand for repair and maintenance of aging infrastructure, the demand for construction technicians is expected to remain stable. Acquiring chemical grouting and high-precision injection technology will increase market value.
