METHOD FOR MANUFACTURING POLYMER GEOGRID Russian patent published in 2017 - IPC B29C55/04 

Abstract RU 2632306 C1

FIELD: construction.

SUBSTANCE: sheet from a polymeric material is perforated and then stretched. The perforations are arranged in rows across the sheet of a polymeric material with the same pitch in the row and the same interval between adjacent rows along the sheet of a polymeric material, and each row of perforations is made with a half-pitch displacement along the row relative to the perforations of the adjacent rows. The perforations are stretched into diamond-shaped cells, which are stretched into cells in the form of hexagons.

EFFECT: improving the mechanical stabilisation of the soil.
