This invention relates to the field of building, and more particularly to geotextile web structures, and can be used for stabilizing water body shorelines and beds, slopes and retaining wall bridge abutments in such areas of construction as the oil and gas, transport and hydraulic engineering industries, amongst others. A blank for producing a seamless geotextile web is made from a polymer sheet material (1) having incisions (2) therein in the form of segments of parallel lines, said segments being of the same length and being arranged in rows (R1, R2,...RN) with the lines of incisions in adjacent rows being offset along the direction of the incisions. Adjacent incisions (2) in the same row (R1, R2,...RN) have a distance S between the ends thereof and the relationship S/L=K1, where K1 is from 0.1 to 0.5; the incisions (2) of adjacent rows (R1, R2,...RN) are at a distance D from each other and have the relationship D/L=K2, where K2 is from 0.1 to 0.7. At the ends of the incisions (2) there are openings (3) which are oval or circular in shape. A seamless geotextile web comprises at least one blank stretched in a direction perpendicular to the lines of the incisions (2) to form a three-dimensional cellular structure. The technical result is an increase in the tensile strength of a geotextile web and a reduction in the outlay entailed in manufacturing same. |
