Geomat

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
