FIELD: construction.
SUBSTANCE: invention relates to construction, namely to geowebs intended for use as reinforcing and separating layer in structures of road bed for linear transport and geotechnical structures. Method of producing polymer geoweb includes perforation and subsequent drawing of sheet made from polymer material. Perforation holes are made in the form of isosceles triangles and arranged in lines across sheet along straights coinciding with bases of triangular openings in the row. Rows consisting of triangular holes identically oriented along sheet are arranged with pre-set pitch. Triangular holes of each row are alternated with oriented in opposite direction triangular holes of the other row. Drawing of perforated sheet is performed longwise and then crosswise.
EFFECT: technical result consists in improvement of geoweb breaking strength due to better orientation of polymer material in strips, ribs.
