ICRI CSRT Grade 1 case studies
ICRI CSRT Grade 1 · Put your knowledge to work in context.
The ICRI Concrete Surface Repair Technician (CSRT) Grade 1 credential is an entry-level certification for people who perform or supervise hands-on repair of concrete surfaces - typically field technicians, apprentices, inspection helpers, and junior quality-control staff working on bridges, parking structures, industrial floors, and water infrastructure. It signals that a candidate understands why concrete deteriorates, how to prepare a substrate correctly, how to select and place repair materials, and how to work safely and document the job. The ICRI CSRT Grade 1 case studies are 5 cases and about 2,514 words.
