Non Woven Geotextile (Polyester Staple Fiber Needle Punched Geotextile)
Overview
The needle punched non woven geotextile is an efficient and affordable solution for soil protection and treatment. The nonwoven geotextile fabric is made from polyester staple fiber that undergoes carding, lapping, and needling processes. Because of its high tensile strength and resistance to tearing, this non woven geotextile is ideal for environmental engineering, road paving, dam construction, and water and soil treatment. Because it is adaptable and made of flexible fibrous tissue, the polyester staple fiber needle punched geotextile won't be blocked and is permeable even under high pressure conditions.
Functions
1. Separation
The non woven geotextile separates building materials of different sizes, density, or consistency and prevents two or more kinds of material from mixing with soil, preserving the independent structure and function of all materials. This geosynthetic product also enhances the bearing capacity of buildings.
2. Filtration
Our PET needle punched non woven geotextile is a good filtration layer that prevents clay from passing through while allowing water and gas through, so it's a stable textile for water and soil engineering projects.
3. Drainage
The polyester non woven fabric exhausts or redirects excess liquid and gas within the soil via an interior drainage channel.
4. Reinforcement
Our needle punched non woven geotextile reinforces tensile strength and non-deformability of soil so the building structure is more stable.
5. Protection
The polyester geotextile effectively disperses or redirects stress caused by concentrated water currents, thus protecting soil from external damage.
