FIELD: building.
SUBSTANCE: group of inventions relates to the field of building materials intended primarily for drainage of transport structures. The geogrid for manufacturing a drainage geocomposite comprises longitudinal and transverse ribs formed from a thermoplastic biaxially oriented polymer material. The longitudinal and transverse ribs have different thicknesses, wherein the transverse ribs of the geogrid are made thinner, and the longitudinal ribs are made thickened, with the ratio of thickness A of the longitudinal ribs to thickness B of the transverse ribs in the range from 1.2 to 2.5.
EFFECT: increase in the strength of the drainage geocomposite.
