Fibre is one part of the ground-support system
Begin with the ground condition, excavation geometry, support duty and the engineer-approved combination of shotcrete, bolts, mesh and other measures. A fibre cannot by itself guarantee ground stability or eliminate rockfall risk.
Wet- and dry-mix conditions
Record the actual process: batching and dosing, transport distance, spraying equipment and openings, water addition, rebound, dust controls, sump or dewatering conditions, layer thickness and early-strength requirements. Dry- and wet-mix routes must be reviewed separately because their control points are not the same.
Evidence and trial
Where panel energy absorption is relevant, identify the specified method and report source, including EN 14488-5 when required. Final dosage and suitability remain subject to the project specification, equipment trial and qualified approval.
