FIELD: construction.
SUBSTANCE: invention relates to construction, namely, to volumetric geogrid structures, and can be used for slopes strengthening in oil and gas, transport, hydraulic engineering and other construction industries. Geogrid has at least one element formed by sheet of polymer material, in which there are slots of equal length, symmetry axes of which are parallel to each other, arranged in rows with offset of slots of adjacent rows relative to each other in longitudinal direction. Slots are made essentially in the form of sections of straight lines so that at movement of edges of each of slots in mutually opposite directions a cell is formed with front and rear walls, at that, at least one element is formed on the condition: 0.1≤d/h≤8, where d is distance between cell rear wall outer surface and cell front wall outer surface; h is distance between rows, in which slots have no displacement relative to each other.
EFFECT: technical result consists in improvement of geogrid strength to break while providing simplicity of its manufacture and efficient use.
