Explore our industry-validated range of filtration, drainage, separation, and reinforcement products, fabricated to match rigorous international standards.
In modern civil engineering, the selection of material specifications is a critical determinant of both construction cost and engineering integrity. The 1m x 50m geotextile roll has emerged as a global standard for small to medium-scale civil projects, landscape engineering, municipal drainage, and subgrade stabilization. This specific dimension balances manual handling efficiency with physical coverage, minimizing overlap waste while ensuring rapid deployability on site.
With a width of exactly 1 meter, these rolls are uniquely suited for trench installations, slope borders, and localized filtration layers. Unlike larger 4m-wide industrial rolls that demand specialized heavy machinery for deployment, the 1m X 50m format can be easily managed by a two-man crew, drastically reducing labor cost metrics on complex, tight-access jobsites. The 50-meter length represents the optimal trade-off between roll weight and continuity, ensuring fewer joints and maintaining strong, uninterrupted mechanical protection across the project zone.
Prevents mixing of subgrade soils and sub-base aggregates. Ensures long-term bearing capacity of transport infrastructures, railways, and structural foundations.
Delivers exceptional water flow rates parallel to the plane of the geotextile, relieving hydrostatic pressure and protecting structural components from water accumulation.
Engineered to absorb stress and distribute concentrated loads. High tensile strength combined with high elongation preserves performance under ground settlement.
Geotextile specifications vary depending on whether the project requires a woven or non-woven structures. Filament non-woven geotextiles utilize 100% virgin polyester (PET) or polypropylene (PP) continuous fibers, thermal-bonded or needle-punched to create a robust three-dimensional mesh structure.
| Property Parameter | PET Filament Non-Woven | PP Staple Fiber Non-Woven | Test Standard Reference |
|---|---|---|---|
| Mass per Unit Area (gsm) | 100 g/m² - 800 g/m² | 100 g/m² - 600 g/m² | ISO 9864 / ASTM D5261 |
| Tensile Strength (kN/m) | ≥ 9.5 kN/m (at 200gsm) | ≥ 7.5 kN/m (at 200gsm) | ISO 10319 / ASTM D4595 |
| Elongation at Break (%) | 40% - 80% | 50% - 100% | ISO 10319 / ASTM D4595 |
| CBR Puncture Resistance (N) | ≥ 1600 N (at 200gsm) | ≥ 1200 N (at 200gsm) | ISO 12236 / ASTM D6241 |
| Permeability Coefficient (cm/s) | 1.0 - 9.0 × 10⁻² | 1.0 - 5.0 × 10⁻² | ISO 11058 / ASTM D4491 |
For critical civil engineering applications, the total mechanical load must be calculated against the puncture and tensile vectors. In landfill and hydraulic engineering, the geotextile functions as a protective shield for geomembranes. Here, selecting a higher gsm (grams per square meter) model of Geotextile 1m X 50m prevents sharp aggregate from puncturing the primary containment liner, securing environmental systems against leakage.

Located at the north end of Fufeng Street, Lingcheng District, Dezhou, Shandong Province, Shandong Hongyue Environmental Engineering Co., Ltd. is a leading manufacturer of geotechnical materials. With a registered capital of 105 million Yuan, the company has built one of the largest integrated production bases of geosynthetics in China, leveraging state-of-the-art manufacturing technologies to serve global projects.
Hongyue's implementation of Factory 4.0 production standards integrates advanced PLC control systems across the fiber extrusion, carding, needle-punching, and thermal bonding lines. By monitoring thermal variables and needle density in real-time, the facility ensures consistent physical parameters throughout every square meter of the 1m X 50m rolls. This high level of automation guarantees that physical specs, such as cross-direction tensile strength and water permeability, are maintained uniformly from roll to roll.
In addition to high-precision manufacturing, our geographical positioning in Lingcheng District provides a significant logistical advantage. Access to major national expressways, freight rail networks, and direct shipping routes via Qingdao Port enables us to reduce delivery lead times and optimize container loading configuration. The resulting reduction in logistics cost yields highly competitive export quotes, benefiting EPC contractors worldwide.
Our manufacturing lines employ modern melt extrusion, precision network distribution, and thermal-draft curing to deliver certified geotechnical materials.
We source top-grade polyester chips, polypropylene filament, and viscose fibers. Raw materials undergo rigorous structural inspections before being released to production.
Polyester and polypropylene chips are melted at high temperatures and extruded through high-pressure screw extruders. Precise temperature controls ensure complete molecular alignment.
The molten polymer is sprayed through fine spinnerets to form continuous fibers, which are laid down on conveyor belts to create a uniform, multi-layered network structure.
The structured web undergoes mechanical needle-punching and thermal bonding under controlled draft speeds, optimizing the tensile strength and puncture resistance.
The finished geotextile is slit to 1m width, measured to 50m length, rolled onto high-strength cardboard cores, and sealed in UV-resistant protective film.
Representative batch samples undergo lab testing for mass variance, tensile strength, and water flow characteristics. Products are approved for shipment only after full validation.
Shandong Hongyue operates under a complete, scientific management system. We have successfully passed the **ISO9001 International Quality Management System**, **ISO14001 Environmental Management System**, and **ISO45001 Occupational Health and Safety Management System** certifications.
Our analytical testing facility is equipped with advanced instrumentation, enabling us to run ASTM-compliant evaluation procedures on site. This guarantees that all products, including our geotextiles, geomembranes, and geocells, maintain excellent mechanical performance. The quality parameters of our products meet or exceed national standards, backed by validation from China's National Testing Center and consistent check-testing by the State Administration of Quality Supervision.
Whether you are ordering 1m x 50m rolls for civil landscaping or high-strength woven structures for transport networks, our quality documentation package remains the same. Every shipment comes with raw material tracking logs, certified test reports, and compliance certificates, ensuring that our products meet the technical standards required by international engineering auditors.
Correct installation is key to unlocking the full technical benefits of geotextiles. Poor laying methods, insufficient overlap, or neglecting to treat joints can compromise the filtration and reinforcement performance of the system, leading to subgrade failure.
Before unrolling the 1m X 50m geotextile, the subgrade must be graded, compacted, and cleared of all sharp rocks, roots, or physical debris that could puncture the polymer mesh.
For separation and filtration, maintain an overlap of 300mm to 500mm. On soft subgrades, hot-wedge welding or handheld industrial stitching is recommended to prevent separation during backfilling.
Do not drive equipment directly on the geotextile. Place aggregate backfill using a push-spreading technique, maintaining a minimum lift thickness of 150mm before compaction.
Our engineering support teams have years of experience working on large-scale civil construction sites. We provide complete technical consulting, drafting site-specific layout guides and recommending mechanical configurations to optimize installation efficiency and reduce material waste.
Our automated production halls in Dezhou, Shandong feature modern manufacturing and quality control infrastructure.
