It is a kind of 3D structural geosynthetic , which is applied to keep the water and land, increase the greening area, and improve the environment. Function: 1.Before the greensward grows, it prevents the surface of the land from the erosion of the wind and rain. 2 .Form compound protection layer with the vegetable, standing the wash-out of the high water level and large speed current. 3.Replace the concrete, asphalt, and block, using in the slope surface protection of roadway, railway, river-way, dyke, and the hillside, etc. Specification of the 3D Geomat Item Spec EM2 EM3 EM4 EM5 Weight per sq.m. ≥(g/m2) 220 260 350 430 　Thickness ≥(mm) 10 12 14 16 　Width≥(m) 2 　Length ≥(m) 30 Vertical tensile strength ≥(KN/m) 0.8 1.4 2.0 3.2 　Horizontal tensile strength ≥(KN/m) 0.8 1.4 2.0 3.2
