¡¡¡¡ A kind of three dimensional
structure new-type geosynthetic material
suitable for  protecting
water and land soil, can effectively keep
water and land soil from flowing away,
increase green land the measure of area,
improve living environment.
Usage:
1. Can substitute concrete, asphalt, stone and
other slope protection material, mainly apply
to slope protection of road, railway, river
lane, dams and dikes, mountain slope, etc.
2. Can prevent land soil from water and rain
erosion before grass covering grows.
3. Can bear scouring of high water space and
high speed water after grass covering grows.
4. Can reduce cost of construction by a wide
margin, cost is only 1/7 of concrete, 1/8 of
stone.
5. Adopt macromolecule material and anti-UV
rays stability, its chemical character is very
stable, no pollution to environment.
6. Easy construction after surface of land is
smooth. 
Operation:
1) Can use small bamboo hole or wooden stick
pass through the whole roll net mat when
construction, then pull net mat along slope,
use wooden nail or plastic nail to fix four
circle of net mat, distance between nail is
30cm, one square meter has10 pieces nails.
2) Length of nail from land surface is usually
15cm, add nails on loose land, length of nail
on up slope is longer than down slope when
construction on high slope.
3) Pay attention to keeping net 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 interval and keep net mat closely
on up net mat.
5) Depth of sowing takes actions that suit
local circumstances, chose long root and
suitable for local climate of grass seeds. 
6) Grass seeds sows in net mat, so can improve
result of complex protection coating.
7) After sowing, land soil must cover net mat.
8) After sowing, 40%-50% of water proportion
in land soil is reasonable, and adding
pressure on surface of land, so benefit for
grass seed's growing.
9) Longitude of connecting should have 60
degree angle, net mat be buried into land soil
30cm when laying on up slope. Bottom of slope
should higher than lever land. Also, open a
ditch on 20cm from up slope, so can easily
irrigate.
10) Laying time is earlier 3-4 month than rain
season.
Note:
1) Do not apply to surface of gravel. 
2) Please chose to use on less than 45 degree
slope.
3) Do not apply to against-sea situation.
4) Only apply to planting grass to protecting
slope, no making deepen tendon-added material.
5) Laying time is earlier 3 month than rain
season when using in against-river situation.
So can guarantee that grass covering firmly
form in or above normal water degree
