Products Introduction: Auto grids are made of macromolecule polymer by the processof being stretched out, formed into lamella, punched regularly and then longitudinaland transverse elongated, which have much higher longitudinal and transversetensile strength, especially in its prophase. These structure can supply a linkingsystem to soil, which be used broadly to enable the permanent bearing capacityof roadbed. Usage: 1,suitable for strengthening road and railway base. Improve loading of roadand railway base, extend usage validity. Prevent surface of road and railway frombreaking. Reduce maintaining charges. Shorten construction time. 2,increaseloading capacity of base. Prevent land soil from sinking; including embankment,slopes, tunnel, airfields, parks, docks and so on. 3,tighten slopes to proof waterand soil from losses. 4, reduce the surface thickness of the ground. 5, preventtunnel from crack occurring. 6, freely construction, save time and cut down thecost of maintenance. producing area:China
