Products Introduction：
Geotech Textiles is a general term for functional geosynthetic materials made from high molecular weight polymers such as polypropylene, polyester, and polyethylene through weaving, non-woven (needle punched, heat bonded), composite, and other processes. It is a "multifunctional structural optimization material" in the field of civil engineering. Its core value lies in integrating the five basic functions of "isolation, filtration, reinforcement, drainage, and protection", providing customized material solutions for different engineering scenarios, and solving common problems such as unstable soil structure, mixed engineering materials, water retention, and insufficient load bearing capacity.
Product Features：
1. Complete functional system, customized and adapted according to needs
Build a functional system of "five core functions+segmented scenario optimization": isolate functions to separate materials of different levels and prevent interlayer mixing; The filtering function intercepts fine particles to ensure smooth drainage; Strengthening function enhances the bearing capacity and shear strength of soil; The drainage function accelerates water diversion and avoids water accumulation; The protective function reduces external wear and environmental erosion. Different product categories focus on different functions, such as woven geotextiles being stronger than reinforced, and non-woven geotextiles being superior in filtering and drainage, which can be accurately selected according to engineering needs.
2. Excellent mechanical properties, stable and reliable load-bearing capacity
Using high modulus polymer raw materials and precision technology, the mechanical properties are highly controllable: the longitudinal and transverse fracture strength of woven geotextiles can reach 50-150kN/m, suitable for heavy-duty reinforcement scenarios; Non woven geotextile has a tear resistance strength of ≥ 3kN, meeting conventional protection requirements; The tensile yield strength of geogrid is ≥ 80kN/m, suitable for high slope reinforcement. At the same time, it has excellent resistance to creep and fatigue, and can maintain structural stability even under long-term loads, ensuring the long-term safety of the project.
3. Weather resistant, corrosion-resistant and broad-spectrum, with strong environmental adaptability
The raw materials have undergone anti UV, anti acid and alkali, and anti microbial degradation treatment, and can work stably in the extreme temperature range of -40 ℃ to 90 ℃. They are resistant to saline alkali soil, seawater immersion, industrial wastewater erosion, and outdoor strong sunlight aging. In complex environments such as coastal areas, mines, and chemical industries, the service life can reach 10-25 years (buried) or 3-10 years (exposed), significantly reducing the frequency and cost of later maintenance.
4. Flexible and diverse forms, convenient and efficient construction
Combining flexibility and plasticity, it can fit irregular terrain such as undulating surfaces, curved slopes, narrow ditches, etc., without blind spots for laying; The product has a variety of forms, including roll, sheet, mesh, etc. The length of a single roll can reach 50-200m, and the width can be selected from 1-8m, reducing the number of overlapping and splicing times. Construction does not require large heavy equipment, manual labor or small machinery to complete the laying, with an efficiency of 500-1200 square meters per day, suitable for different construction conditions.
5. Coordinated economic and environmental protection, with excellent value throughout the entire cycle
The material cost is only 1/5-1/2 of traditional rigid materials such as concrete and steel plates, and the construction labor cost is reduced by more than 30%; In long-term use, due to the improvement of engineering stability, the maintenance cycle is extended by 2-5 times, and the full cycle cost advantage is significant. At the same time, polymer raw materials can be recycled, and some products are made of recycled materials, which is in line with the concepts of green engineering and sustainable development, reducing environmental burden.
