Green Geotextile
1. Effective dust control, good water permeability, good water conductivity and anti-filtration performance.
2. It has the function of reinforcement, which can enhance the stability of soil structure.
3. Excellent corrosion resistance, no insect moth, economical and durable, with good isolation function.
Product description
Green geotextile is a textile used in civil engineering. It is mainly used for the control of railroad slurry mud, roadbed reinforcement, emergency highway paving, to solve the construction of soft land, water conservancy slope protection, reservoirs, dams and drainage ditches of the anti-filtration layer, as well as power plants, such as ash dams, mine tailings dams of the filtration and so on. Soil I cloth in the process of use and soil and other materials are closely related, so the American Laboratory Association to the definition of geotextile: a - all exist in the foundation, soil, rock, soil, pipeline or with any other civil construction materials - together, and as a man-made projects, structures, systems, components of the textile fabric.

The role of geotextiles
1: Separation
The use of polyester staple fiber needle punched geotextile has different physical properties (particle size, distribution, consistency and density, etc.) of the building materials (such as soil and sand, soil and concrete, etc.) for isolation. So that two or more kinds of materials are not lost, not mixed, to maintain the overall structure and function of the material, so that the building carrying capacity to strengthen.
2: Filtration (reverse filtration)
When the water flows into the coarse material soil layer from the fine material soil layer, using polyester staple fiber needle punched geotextile good air permeability and water permeability, so that the water flow through, and effectively carry the flow of soil particles, fine sand, small stones, etc., in order to maintain the stability of the soil and water works.
3：Drainage
Polyester staple fiber needle punched geotextile has good water-conducting property, it can form drainage channel inside the soil body, and drain the excess liquid and gas out of the soil structure.
4：Reinforcement
Using polyester staple fiber needle punched geotextile to enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure to improve the quality of the soil.
5：Protection
When the soil is washed by water flow, it can effectively diffuse, transfer or decompose the concentrated stress, stop the soil from being damaged by external force, and protect the soil.
6：Puncture
Combined with geomembrane, it becomes composite water seepage material and plays the role of puncture.
