Products Introduction：
Geotextile Commercial is a high-performance geosynthetic material designed for large-scale municipal, transportation, water conservancy, and other commercial projects. It is made from polyester (PET) or high-strength polypropylene (PP) as the core raw materials, and is processed through weaving, composite, or needle punching reinforcement techniques, with a weight coverage of 200-1000g/m ² engineering grade specifications. Its core positioning is "the structural strengthening and long-term protection core of commercial engineering", integrating four composite functions of "high-strength reinforcement, efficient filtration and drainage, strict anti-seepage, and anti damage protection". It is designed specifically for commercial projects that can withstand heavy loads and complex environments, and is suitable for scenarios such as highway subgrades, port yards, reservoir embankments, and mine tailings ponds that require strict material performance and service life.
Product Features：
1. Engineering grade mechanical performance, stable and reliable under heavy loads
Using high modulus filament raw materials and precision weaving/composite processes, the longitudinal and transverse fracture strength can reach 30-150kN/m, the tear strength is ≥ 5kN, and the puncture resistance is ≥ 500N, far exceeding civilian grade products; Excellent creep resistance, with a deformation rate of ≤ 2% under long-term constant heavy loads (such as container trucks and mining machinery loads), can effectively disperse stress, prevent soil settlement, and meet the stress requirements of commercial heavy-duty engineering.
2. Composite function integration, full scene protection coverage
Combining multiple functions of reinforcement, filtration, anti-seepage, and protection: the woven structure strengthens the soil bearing capacity, and the needle punched composite layer achieves efficient filtration (permeability coefficient ≥ 1 × 10 ⁻³ cm/s, retention rate ≥ 98%). The composite geotextile layer meets the anti-seepage requirements (permeability coefficient ≤ 1 × 10 ⁻¹¹ cm/s); Single or composite functional products can be customized according to the specific needs of commercial engineering, covering multiple scenarios such as roadbed reinforcement, slope protection, and anti-seepage barriers.
3. Strict weather resistance and corrosion resistance, suitable for complex environments
The raw materials have undergone four levels of stabilization treatment, including UV resistance, acid and alkali resistance, microbial resistance, and chemical corrosion resistance. They can work stably in the extreme temperature range of -40 ℃ to 90 ℃, withstand salt alkali soil, seawater immersion, industrial wastewater erosion, and outdoor strong sunlight aging; The buried service life can reach 15-25 years, and the exposed service life can reach 8-12 years. It is suitable for complex commercial environments such as coastal areas, mines, and chemical industries, reducing maintenance and replacement costs in the later stage.
4. Batch supply, complete technical support
Capable of producing 10000 tons per year, supporting batch orders of over 1000 rolls per order, with controllable delivery cycles (7-15 days for standard specifications); Provide professional engineering and technical services, including on-site investigation, scheme design, construction guidance, assist clients in optimizing material selection and laying processes, ensure accurate matching of product performance with engineering requirements, and reduce engineering risks.
