Abstract: A method of manufacture of geotechnical profiles where thermoplastic material including one or more of polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyethylene or polythene (PE), acrylonitrile butadiene styrene (ABS), or polypropylene (PP), is plasticized in an extruder, pressed through a cross die unit and internal reinforcing profiles in the form of flat bars, arched elements, angled elements, ribbed profiles or sections of any geometry are entered at least in selected cross-section areas of the geotechnical profile where the internal reinforcing profiles are created from one or more of continuous or chopped fiber produced simultaneously or as part of a separate production process.

Abstract: A method of manufacture of geotechnical profiles, characterized in that thermoplastic material, preferably hard and high-impact, PVC and/or PET and/or PE and/or ABS and/or PP, is plasticized in an extruder, after which it is pressed through an cross die unit ant internal reinforcing profiles (2, 4, 6, 8, 10, 12, 14, 16) in the form of flat bars, arched elements, angled elements, ribbed profiles or sections of any geometry are entered to it in the entire volume, and at least in selected cross-section areas of the geotechnical profile (1, 3, 5, 7, 9, 11, 13, 15), whereas these profiles are created from continuous and/or chopped fiber produced simultaneously or as part of a separate production process.
