Biaxial geogrid material is the same as uniaxial geogrid,it ateria is HDPP/HDPE or other high polymer .add some ultraviolet radiation resistant material and carton,by extruding and tensiling from machine direction and cross direction. It structure can from linking and net systerm.be use in the construction of roads and other trafficked areas,earthworks,foundation,retaining structure,reservoirs,and dams and canals,erosion control works(coastal protection and bank revetments),solid waste disposals.Any packing not be removed until grid is to be installed any sizeable voids to be filed.Grid should be pegged down using suitable fixing pins/pegs if necessary.overlap of 300mm to 400mm to be made if approprite.
USAGE:
1) Suitable for strengthening road and railway base,Improve loading of road and railway base,extend usage validity.Prevent.surface of road and railway from breaking. Reduce maintaining charges. Shorten construction time.
2) Increase loading capacity of base.Prevent land soil from sinking. Beautify land,convenient construction.saving time and labor .
3) Suitable for second strengthening after using one-direction gcosynthetic stretching grille to strengthen ,Further strengthening ladn slope,prevent land soil form flowing away,affecting traffic,Makegrass growing inturn,beautify environment,and reduce pollution.
4) Suitable for protecting slope of road and highway.Prevent stone from sliding .keep road and railway normal traffic.Suitable for strengthening road,railway and bridge hole,Prevent bridge hole from breaking,reduce maintaining chartes, shorten thickness of surface,saving cost,Filtering and protecting.
