USAGE
1）Can instead of concrete ,asphalt ,stone and other slope protecting material ,mainly apply to slope of road ,railway and river lane.Dam and dokes ,mountain slope etc.
2）Can prevent land soil from water and rain erosion before grass covering grows.
3）Can bear sourcing of high water space and high-speed water after grass covering grows.
4）Can reduce cost of construction by a width margin ,cost is only 1/7 concrete ,1/8 stone.
5）Adopt macromolecule material and anti-UV rays stability ,its chemical character is very stable ,no pollution to enviroment.
6）Easy construction after surface of land is smooth.
OPERATION
1）C an use bamboo pole or wood stick pass the whole roll net mat when construction ,then pull net mat along slope ,use wooden nail or plastic nail to fix circle of net mat ,distrance between nails is 30cm , one spuare meter has 10 nails.
2）Length if nail from land surface is usually 15cm ,add nails on loose land ,length of nail on up slop is longer than on down slope when construction on high slope.
3）Pay attention to keep netting mat smoothly and add nails on sudden change place topography .
4）Check carefully connecting .Length of connecting is 2cm ,nail must be fixed in connecting place .nails density is added 100% ,there is no internal and keep net mat closely on up net mat. Width of bore diameter on up nail is two times of netting mat hole ,so can suppress on vertical direction.
5）Depth of sowing takes actions that suil local circumstance,chose long root and suitable for local climate of grass seeds.
6）Gradd seeds sows in net mat ,so can improve result of complex protect coating.
7）After sowing ,land soil must cover the netting mat.
8）After sowing ,40-50% water proportion in land soil is reasonable ,and adding pressure on surface of land ,so benefit for grass seeds growing.
9）Longitude of connecting should have 60-degree angle ,netting mat must be buried into land soil 30cm when laying on up slope .Bottom of slope should higher than level land .Also ,opena ditch 20cm from up slope ,so can easily irrigate.
10） Lying time is earlier 3-4months than rain season.
NOTE:
1）Don't apply to surface of gravel.
2）Please choose to use less than 45-degree angle slope.
3）Don't apply to against-sea situation.
4）Only apply to planting seeds for protecting slope ,no making deepen tendon-added material .
5）Lying time is earlier 3months than rain season when use in against-river situation . So can guarantee the grass cover firmly from in or above normal water degree.
