Nutrition geotextile in water environmental engineering .
Polyester filament geotextile is made by polyester textile needle consolidation , product specifications from 80-800g/m2 , it is geosynthetic application in geotechnical and civil engineering , they are arranged in three-dimensional structure of the fiber . In addition to having good mechanical properties, but also has a good aspect to the drainage performance and good elongation properties and high resistance to biological , acid , anti-aging chemical stability . Meanwhile , it also has a wide range of pore size , pore distribution tortuous , excellent permeability and filtration performance .
1. Simple and fast construction
2. Achieve the greening effect quickly after construction
3. Due to the grass and composite fiber fabrics become into one integration, so it has the ability of certain degree of flow resistance for the water rising before the grass survive.
4. Composite fiber fabric is a continuous structure from slope top to slope toe, both ends are fixed, has high water flow resistance.
5.0 m length and 1.05 m width. Reverse side all used filter material. Grass seeds: Bermuda grass (warm season grass), Bahia grass (warm season grass), Kentucky bluegrass (cold season grass), Tall fescue grass (cold season grass), Red fescue grass (cold season grass). Plant height: 0.1 ~ 0.5 m.
