Slope face (norimen) protection worker (stone facing work)
のりめんほごこう（いしばりこうじ）
Industry & Occupation
Classification
Summary
Specialized construction work that uses stone materials to protect and decorate slope faces, preventing collapses and ensuring safety and aesthetics.
Description
Slope protection work (stone facing construction) involves covering and protecting the surfaces of slopes (slope faces) in areas such as roads, riverbanks, and developed land using stone materials. First, the slope face is shaped and compacted, anchors and drainage pipes are installed, and foundation mortar is applied. Then, stones are selected, processed, and placed. Mortar is filled into the joints to secure them, followed by finishing adjustments and cleaning to complete the work. Operation of heavy machinery, scaffolding work, and safety management are essential, requiring teamwork and coordination with site supervisors. After construction, stability inspections and repairs are performed, contributing to infrastructure maintenance.
Future Outlook
With increasing demand for infrastructure aging countermeasures, land development, and road maintenance in Japan, job openings for slope protection work are expected to remain stable. Efficiency improvements through ICT and precast technology will further emphasize the expertise of technicians.
