Specifications: Geotextile 1.a new type of construction materials 2.use in construction projects 3.excellent filtration effciency, isolation Geotextile Features: Geotextile is a new type of construction materials which is defined to use in construction projects. The main roles of geotextile include filter, water treatment materials and geo-reinforce. Materials. Needled staple fiber geotextiles show excellent filtration effciency, isolation, reinforced protective effect, high tensile strength, good permeability, high temperature resisting, anti-freezing, anti-aging, corrosion resistance. Aplications fields: Widely used in the fields of water conservancy, hydroelectric power, roads,railways,ports,airports,sports stadiums,tunnels,coastal beach, land reclamation,environmental protection and so on. They played the roles as isolation, filtration,drainage, reinforcement, protection, and sealing.

If the virtual specification fall between two adjacent regular values, the examination index of which sgould be determined by interpolation method. If the virtual specification exceed the ranges list in the table, the examination index of which should be fixed by negotiation. 2) The standard value followed the design or agreement. 3) It is a reference index controlled in the production. It would follow the design value if it is required by customers. Geotextile
