Product Overview

Description

PP needle punched non-woven geo fibre

Product Description

Made from PP(polypropylene) or PET(polyester) short fiber by nonwoven needle punched manufacturing process, it has isolation, filtration, drainage, reinforcement, protection and maintenance etc. function.

Property

Separation: the loss of two or more materials, not mixed, maintain the overall structure and functional materials, the load bearing capacity of strengthened structures.
Filtration: when the water flows into the coarse material by fine soil layer, the use of staple fiber needle punched geotextile has good air permeability and water permeability, allows water to flow through, and effectively carrying current soil particles, sand, small stones and so on, in order to maintain the stability of soil and water engineering.
Drainage: the water guide with good properties and short fiber needle punched geotextile, it can be formed inside the soil drainage channel, the excess liquid and gas in the outer row of soil structure.
Reinforcement: the tensile strength of the reinforced soil and anti deformation capacity utilization of staple fiber needle punched geotextile, enhanced the stability of structures, to improve the soil quality.
Protection and maintenance function: water on soil erosion, effective will be concentrated stress diffusion, transfer or decomposition, to prevent soil from damage by external force.
Good flexbility, resistant to corrosion, resistant to acids and alkalis, anti-oxidation.
