Non-woven Polypropylene Geotextile
Description
Technical Parameters
Many people mistakenly view geotextile as a simple layer of cloth with no technical content-this assumption is completely incorrect. In road, dike and landfill projects, non-woven polypropylene geotextile fulfills five core functions: separation, filtration, drainage, reinforcement and protection, directly impacting the service life and safety of engineering works. Our non-woven polypropylene geotextile is manufactured from 100% polypropylene staple fibers consolidated via needle punching. The three-dimensionally interlaced fiber structure forms a porous framework delivering favorable water permeability while effectively blocking soil particle loss. Key indicators including tensile strength, tear strength and CBR burst strength of this non-woven polypropylene geotextile all exceed national standard requirements. Multiple highway projects we have serviced have maintained stable subgrade conditions over 10 years of operation with this product.
Different engineering works impose drastically different gram weight requirements for geotextiles: 100-150g suffices for temporary protection, while 600-800g may be required for filter layers in landfills. Our production lines cover the full gram weight range of 100g/㎡ to 800g/㎡ with adjustable widths from 1m to 6m and customizable roll lengths. Needle punching density and process parameters can be adjusted per clients' specific performance demands to ensure every batch meets precise standards. Our non-woven polypropylene geotextile is blended with UV stabilizers to maintain a long service life even under exposed conditions. For agents, comprehensive specifications, fast delivery and stable quality are three major advantages to help you secure numerous orders.

Qualification Certifications
Our non-woven polypropylene geotextile is manufactured in strict compliance with national standard GB/T 17638, with ISO9001 quality management system certification and ISO14001 environmental management system certification obtained. We can provide SGS, BV and other third-party testing reports covering a full suite of indicators including physical mechanical performance, hydraulic performance and durability. We have participated in the formulation of multiple industry standards, holding certain technical discourse power in the geosynthetic materials sector. These qualification certifications act as hard currency for you to bid on international engineering projects, helping you stand out in technical evaluation rounds.
Packaging & Transportation
Geotextile features large volume and light weight, making transportation cost control critical. Our standard packaging adopts roll form, with each roll wrapped in plastic woven cloth for moisture protection and paper or wooden cores fitted at both ends to prevent deformation. 6m-wide products can be folded for packaging to optimize container loading rates. Based on your order volume and destination port, we can design optimal container loading schemes to maximize utilization of 20ft or 40ft containers and reduce ocean freight costs for you. Multiple trade terms including EXW, FOB and DDP are supported, with photos taken throughout container loading for full visibility of cargo status.
Frequently Asked Questions
Q: How to select the gram weight of geotextile?
A: Generally speaking, 200-300g is used for road separation layers, 300-400g for dike reverse filtration, and 500-800g for landfills. Specific selection must align with engineering design requirements, and we can provide technical recommendations.
Q: Can custom colors be produced?
A: White is the standard color; black, gray and other colors can be customized. Black geotextile is blended with carbon black for superior UV resistance, suitable for long-term exposed use.
Q: What is the minimum order quantity?
A: Standard specifications require a minimum order of 1,000 ㎡; MOQ for special specifications and colors requires separate discussion.
Q: What is the delivery cycle?
A: Standard specifications are delivered within 1 week, customized specifications within 15 days.
