Geosynthetic Materials 210726 Testing Geosynthetic materials are a general term for synthetic materials used in civil engineering. As a civil engineering material, it is made from artificially synthesized polymers (such as plastic, chemical fibers, synthetic rubber, etc.) into various types of products, which are placed inside, on the surface, or between various soil masses to strengthen or protect the soil.
