Geosynthetics comprehensive mechanical testing machine

Geosynthetics were once known as "geotextile" and "geomembrane".With the needs of engineering, new varieties of this type of materials are constantly emerging, such as geogrids, geonets and geomold bags, geonet pads, geostrips, composite geomembranes, bentonite waterproof blankets, composite drainage nets, etc.This comprehensive mechanical testing machine for geosynthetic materials can simultaneously complete the mechanical property testing of various geosynthetic materials, such as geogrid tensile test, limit separation, solder joint separation, solder joint peeling force test, geotextile bursting/puncture, wide strip tensile test, T-shaped tear test, etc., one machine is multi-purpose, convenient and fast.

Comprehensive testing machine for geotechnical materials based on standards:
