Geosynthetic Material Comprehensive Mechanical Testing Machine

Geosynthetic materials were once referred to as "geotextiles" and "geomembranes." With evolving engineering needs, new varieties of these materials have continuously emerged, such as geogrids, geonets, geofabric forms, geomatts, geostrips, composite geomembranes, bentonite waterproof blankets, and composite drainage nets. This comprehensive geosynthetic material mechanical testing machine can simultaneously perform various mechanical property tests on different types of geosynthetic materials, including geogrid tensile tests, ultimate separation, weld point separation, weld point peel force testing, geotextile burst/puncture resistance, wide-width tensile tests, T-type tear tests, and more. It offers multiple functions in one machine, making it convenient and efficient.
