Scope

This document is applicable to basalt fiber geogrids made from basalt fiber untwisted roving as the main raw material, which are woven and surface-impregnated. They are mainly used in various fields such as reinforcing dams and roadbeds, slope protection, reinforcing cave walls, and permanent load-bearing foundation reinforcement and crack resistance in airports, parking lots, docks, and warehouses. For basalt fiber geogrids used in other fields, they can be used as a reference. This document specifies the terms and definitions, models, appearance dimensions, physical and chemical properties, test methods, inspection rules, marking, packaging, transportation, and storage of basalt fiber geogrids.
