Nonwoven Geotextile for Soil Reinforcement
Specifications
Nonwoven Geotextile for Soil ReinforcementFilament Nonwoven Polyester Geotextile
Description
Filament nonwoven polyester geotextile are manufactured from the extrusion of polyester resin into continuous filament product which may be then further processed by spinning process.
Filament nonwoven polyester geotextile are used in a multitude of construction applications. Nonwoven geotextiles are ideally suited for applications of filtration, drainage,separation,liner protection, road maintenance and soil reinforcement.
Applications
1. Filtration
The extremely high prosity of nonwoven geotextiles allows water flow while limiting fines migration. The complex flow path minics a natural filter and provides considerable cost saving over a traditional graded filter.
2. Separation
The separation geotextiles ensures the soft subgrade does not contaminate the fill material and the quality of the fill is maintained, The high elongation characteristics of nonwoven geotextiles limit installation damage, which ensures long term performance.
3. Drainage
The complex needled punched structure acts to retain a large range of the soil particles without reducing the permeability requirements of the drain. The three dimensional structure of a nonwoven needle punched geotextile ensures high flow rates and hence excellent drainage performance.
4. Protection
Nonwoven needle punched geotextile provide excellent protection to liner systems in landfills, heap leach pads and pond lining applications. The inclusion of a geotextile protection layer can extend the life and maintain the integrity of the lining system for many years.
5. Road maintenance
Nonwoven needle punched polyester paving fabric, which provides stress relief, waterproofing and reduces reflective cracking functions in new paved roads.
6. Reinforcement
The nature of the continuous filaments ensures good strength characteristics while the needle punching allows a high level of flexibility and drainage of the surrounding soil.
Typically the strength range of the filament nonwoven geotextiles is between 4.5KN/M to 50KN/M
