Industry-approved stabilization, containment, and barrier systems optimized for major civil and infrastructure works.
Understanding the engineering mechanics of aggregate separation, dynamic loading distribution, and soil subgrade reinforcement.
In modern civil engineering, infrastructure development, and hardscaping, the integrity of a gravel layer is heavily dependent on the stability of the underlying soil subgrade. Placing gravel directly onto soft, silty, or clayey subgrades triggers a destructive phenomenon: subgrade intrusion and aggregate migration. Under continuous vehicle or foot loads, the gravel particles are pushed down into the soft subgrade, while the subgrade soils migrate upward into the gravel voids. This process ruins structural load capacity, compromises drainage, and leads to surface deformation, ruts, and potholes.
Implementing a specialized geo fabric under gravel (geotextile) establishes an engineered physical barrier that maintains separation. Designed with high tensile strength and calibrated permeability, our geotextile fabrics isolate subgrade soils while allowing water to filter through. This separation guarantees that the aggregate layer maintains its thickness, structural properties, and porous flow capacity over its operational lifespan.
From an engineering perspective, geotextile layers under aggregate structures serve four primary functions:

Matching structural load requirements with standard geofabric properties for global construction operations.
Commercial buyers, infrastructure engineers, and procurement agents must evaluate specific physical and mechanical metrics when sourcing geotextiles for gravel applications. Selecting the right fabric weight, tensile properties, and puncture resistance ensures the long-term integrity of gravel roads, parking structures, and railway bases. The table below matches common project demands with appropriate material properties.
| Application Scenario | Recommended Fabric Type | Mass Per Unit Area (g/m²) | Grab Tensile Strength (kN) | CBR Puncture Resistance (kN) | Key Engineering Purpose |
|---|---|---|---|---|---|
| Light Traffic Driveways & Walkways | Non-Woven PP / Needle-Punched | 150 - 200 g/m² | ≥ 0.8 kN | ≥ 1.5 kN | Filtration & weed prevention under light gravel |
| Commercial Parking & Service Access | Non-Woven Filament Polyester | 250 - 350 g/m² | ≥ 1.5 kN | ≥ 2.5 kN | Separation, load distribution, and rut prevention |
| Heavy Haul & Heavy Industrial Roads | High-Strength Woven PP / Polyester | 400 - 600 g/m² | ≥ 3.0 kN | ≥ 4.5 kN | Subgrade reinforcement and aggregate stability |
| Railway Ballast & Drainage French Drains | Needle-Punched Continuous Filament | 300 - 450 g/m² | ≥ 2.0 kN | ≥ 3.5 kN | High transmissivity, puncture resistance from ballast gravel |
| Water Conservancy & Hydraulic Slopes | Composite Geotextile with Geomembrane | 500 - 800 g/m² | ≥ 4.5 kN | ≥ 6.0 kN | Seepage barrier, filtration, and erosion protection |
Roll dimensions are highly critical for reducing waste during installation. Shandong Hongyue supplies rolls in widths ranging from 2.0 meters up to 6.0 meters, and lengths from 50 to 200 meters. This customization reduces overlap frequency (typically 300mm to 500mm), lowering material costs by up to 12% on highway systems.
Polypropylene (PP) offers excellent chemical resistance in highly alkaline or acidic subgrade environments. Polyester (PET) features high tensile strength at low strain rates and superior creep resistance, making it suitable for long-term load bearing applications under heavy industrial gravel bases.
A step-by-step look at our automated production line, showing how raw polymers are transformed into certified geotextiles.
Geotextile is widely used in civil engineering materials, with filtration, isolation, reinforcement, protection and other functions, its production process includes raw material preparation, melt extrusion, mesh rolling, draft curing, winding packaging and inspection steps. It requires precise control across multiple links of processing, while factoring in environmental protection and durability. Modern production equipment and technology have been widely adopted, significantly improving production efficiency and geotextile quality.
Shandong Hongyue uses multi-layer co-extrusion spinning equipment and high-density needle-punching boards. This ensures the fibers form a stable three-dimensional structure. This 3D fiber matrix gives our non-woven geotextile high physical permeability alongside isotropic tensile properties, meaning the fabric resists tearing and stretching evenly in all directions.
The main raw materials of geotextile are polyester chips, polypropylene filament and viscose fiber. These raw materials need to be inspected, arranged and stored to ensure their quality and stability before processing.
After the polyester slice is melted at high temperatures, it is extruded into a molten state by a screw extruder, and polypropylene filament and viscose fiber are added for mixing. Temperature and pressure parameters are precisely controlled to ensure a uniform melt.
After mixing, the melt is sprayed through the spinneret to form a fibrous substance and form a uniform network structure on the conveyor belt. Thickness, uniformity, and fiber orientation are controlled at this stage.
After laying the net into rolls, draft curing treatment is performed. In this process, the temperature, speed, and draft ratio are precisely controlled to ensure the final mechanical strength of the geotextile.
The cured geotextile is rolled up and packed for subsequent construction. The length, width, and thickness are measured to ensure they match the specific requirements of the civil design.
At the end of each production link, the geotextile is tested for physical, chemical, and dimensional properties. Only batches meeting national and international quality standards are approved for export.
Our quality assurance program runs 24/7. Testing includes CBR puncture resistance (ASTM D6241), tensile strength and elongation (ASTM D4632), water permeability (ASTM D4491), and Apparent Opening Size (AOS, ASTM D4751). By checking every batch, we provide engineering teams with reliable performance data, ensuring long-term stability under heavy gravel roads.
How geotextiles and geomembranes work together to stabilize structures and manage water flow.
Geomembrane, as an efficient anti-seepage material, plays a vital role in water conservancy projects. Its excellent anti-seepage performance, lightweight construction characteristics, and low relative cost make geomembrane an indispensable part of modern water conservancy and municipal works.
In hydraulic systems, combining geomembranes with geotextiles creates composite barrier networks. The geotextile protects the thin geomembrane from puncture damage caused by gravel and subgrade rocks. At the same time, it allows gas and water pressure to vent from underneath, preventing the liner from lifting or shifting.
Because reservoirs are built in valleys or low-lying areas, geological conditions are complex. It is essential to prevent water loss through the reservoir bottom and surrounding rock. Using a protective geofabric combined with a high-durability geomembrane provides a reliable, long-term barrier that improves the safety and stability of the entire reservoir structure.
Dikes are critical structures designed to protect downstream areas from flooding. Unpredictable subgrade movement and piping erosion can compromise these levees. Installing high-strength geotextiles under protective rock armor or gravel stabilizes the soil slope and prevents internal erosion, safeguarding municipal infrastructure.
Rivers and agricultural channels are essential components of water conservancy systems. They regulate water flow, protect farmland, and support local ecosystems. Installing a composite barrier system prevents channel bed erosion and water loss through seepage, ensuring consistent flow rates throughout the year.
Our commitment to sustainable production, long-term durability, and smart geosynthetic technologies.
Polymers like polypropylene can degrade when exposed to sunlight during installation. Shandong Hongyue integrates advanced hindered amine light stabilizers (HALS) into the polymer melt. This treatment keeps the fabric strong and stable even after long-term UV exposure, ensuring it holds up during long project timelines.
For temporary access roads and agricultural applications where long-term synthetic barriers are not needed, our R&D team is working on natural and PLA-based biodegradable options. These fabrics stabilize the soil during construction and then break down naturally over several years, minimizing environmental impact.
For critical infrastructure projects like high-speed railways and earth dams, we are developing geotextiles embedded with fiber-optic strain and temperature sensors. This technology allows operators to monitor structural deformation and locate internal erosion in real-time, helping prevent failures before they occur.
