New GRC Crack Treatment Process: Decision Tree for Assessment and Grading, Observation and Judgment, and Timing of Repair

The three-step process for treating new cracks in GRC (Glass Reinforced Concrete) is as follows: first, classification (surface shrinkage microcracks vs. through-force cracks); second, observation (attaching plaster monitoring stakes to observe crack propagation); and third, repair (sealing microcracks and treating propagated cracks according to structural repair techniques). This article presents the decision-making process.
