3D Erosion Cntrol Mat

3D Geomat  is a geosynthetic material used in slope protection, soil and water conservation, and other fields. Here is a detailed introduction:

Material Composition: It typically uses high-molecular polymers such as polypropylene (PP) or polyethylene (PE) as the base material. Some products embed high-strength glass fibers or polyester fibers to enhance tensile strength. Ecological additives such as UV protectants, biodegradable components, or plant growth promoters may also be added.

Structural Characteristics: It has a three-dimensional space formed by multiple interwoven layers, with a porosity generally between 60% and 80%. The surface layer is a loose fiber layer to trap seeds, the middle layer is a reinforcing layer to prevent structural deformation, and the bottom layer is an impermeable layer to reduce soil erosion. Its longitudinal tensile strength needs to reach 8-15 kN/m, and its transverse tensile strength is not less than 6-10 kN/m.

Functional Advantages: The three-dimensional structure of the vegetation netting can effectively fix soil particles, reduce surface runoff velocity, promote water infiltration, and reduce soil erosion by more than 60%. The vegetation root system and the netting form a "soil-root-net" composite system. When the vegetation coverage reaches over 90%, the overall shear strength of the system can be increased by 3-5 times.
