Fiberglass geogrid is a new geosynthetic material woven from fiberglass filament. Fiberglass geogrid with high tensile strength can increase the bearing capacity of the ground to extend service life. In addition, the structure of fiberglass is stable. So it can be used in soft soil, cement, concrete, asphalt ground to stabilize the foundation and increase the bearing capacity. Compared with plastic geogrid, fiberglass geogrid has good heat resistance, it can work at high temperatures.
