Industry & Occupation
Classification
Summary
A concrete injection worker is a specialist technician who injects grout material for ground improvement or crack repair to enhance the strength and durability of structures.
Description
Concrete injection workers (civil engineering works) inject cement-based or chemical grout materials into concrete structures after placement or into soil ground to perform crack repair, void filling, ground improvement, waterproofing, water stopping, etc. On site, they handle injection planning, management of injection pressure and speed, post-injection curing management, etc., requiring construction accuracy, quality control, and safety management. They also collaborate with construction management technicians on method selection and material consideration.
Future Outlook
With increasing needs for infrastructure aging countermeasures and ground improvement, the demand for specialized injection technicians remains stable, and productivity improvements are expected through integration with IoT and automation technologies.
