Polypropylene continuous filament nonwoven geotextile for construction - 350g/square meter

Needle punched Nonwoven Filament Geotextile 350g/sm for highway

Geotextile is a new construction material, which the raw material is polypropylene fiber,polyester fibre,acrylics,nylon and other high polymer, without chemical additives and heat treatment. It is environment friendly construction material.

Based on the length of the fiber, it can be divided to Filament Geotextile and short Filament Geotextile. The tensile strength of filament geotextile is higher than short filament geotextile. The unit weight is from 100g/m2 to 800g/m2. Getextile has excellent mechanical properties, superior water permeability, filtrability and deformation adaptive faculty, at the same time, it can resist to corrosion and also anti-ageing. It can isolate,filtration,dewatering,protect,firm,strengthen.

The function of geotextile:

• Geotextile has good air permeability and water permeability which can pass the water out and intercept the sand running-down
• Geotextile has high water diversion property, it can form drainage passageway, transpire the surplus liquid and gas
• High water permeability even under the pressure of soil and water
• Spread, transfer or decompose the concentrate stress effectively to avoid the soil be damaged by outside affection
• To prevent the freestone upper and lower level, soil and concrete mixed
• Polypropylene fiber or polyester fiber and other chemical fiber as raw material, acid-alkali-proof, non-corrording, non warm-eaten,antioxidant
• Light weight, convenient to use, easy construction, shorten working-period, increase economic efficiency
• Make use of geotextile to strengthen the tensile strength and anti-deformation property of soil, increase the stability of building structure, and also improve the soil quality
