Protect the slope surface of a roadway, railway, riverway or a hillside with this 3D geomat erosion control mat. Constructed of a 3D structural geosynthetic, high polymer synthetic material that is applied in soil and water conservation, this material offers flexibility. You can fill 90% of its space with soil, sand and the roots of the plants that grow through balance. The growth of grass holds the gauze pad, turf, soil surface firmly together due to plant roots extending 30 cm to 50 cm below the ground. It then forms a green composite coating solid layer. This 3D geomat can effectively solve the problem of rock slope and be used in high and steep slope surface protection, benefitting the stability of the slope. It significantly improves the overall and local stability of the slope while being conducive to the growth of slope vegetation. Stable performance and strong corrosion resistance ensure lasting use in harsh environments without damage. Material: HDPE(High Density Polethylene).
