The geotechnological grid of the glass fibre is abbreviated as glass fibre geogrid, a new-typed geotechnological sill, have high tensile strength , better elastic mould amount , low coefficient of elongation ,able to bear high and low temperature, and ageing-resistant.Especially after the grid surface being coated ,which improve with pitch or complex performance of concrete, have strengthened the wear-resisting performance of this sill and resisted the ability of shearing.
