Characteristics: the use of polyester staple fiber needle geotextile for building materials have different physical properties (particle size distribution, consistency and density, etc.) (such as soil and sand, soil and concrete, etc.) in isolation. So between the two or more materials is not lost, not mixed, maintaining the overall structure and function of materials, so that load bearing capacity of structures strengthened. When the water flows into the coarse material from fine soil materials soil, the use of polyester staple fiber needle geotextile good air permeability and water permeability, so that water flows through, and the effective current carrying soil particles, sand, small stones, so as to stable soil and water engineering. Polyester staple fiber needle geotextile has good water guide performance, which can be formed inside the soil drainage channels within the soil structure within the excess liquid and gas efflux. The use of polyester staple fiber needle geotextile reinforced soil tensile strength and resistance to deformation, enhance the stability of the building structure in order to improve soil quality. When the flow of soil erosion, effective stress will focus on proliferation, transfer, or decomposition, to prevent soil damage by external force while. High tensile strength, permeability, high temperature, anti-freeze, anti-aging, corrosion, moth-eaten.
Uses: Widely used in railway embankment reinforcement, conservation road surface, sports hall, dams protection, hydraulic structures isolation tunnel in a coastal beach, land reclamation and environmental protection projects.
