Permittivity and AOS (Apparent Opening Size)

These two interrelated properties are critical to the filtration performance of woven geotextiles. Permittivity measures the fabric’s ability to transmit water, while AOS indicates the size of particles the fabric can retain.

• AOS is typically measured in millimeters (e.g., AOS 75, 100, 150) and should be smaller than the D85 particle size of the adjacent soil to prevent soil migration.
• High permittivity ensures efficient water flow, reducing hydrostatic pressure and preventing clogging.
• Ideal fabrics balance fine filtration (low AOS) with high water flow (high permittivity).
• For critical drainage applications, look for permittivity values above 0.1 sec⁻¹ and AOS between 75–150 microns.

Technical tip: Use the formula AOS ≤ 0.5 × D85 as a rule of thumb for effective soil retention.

Material and Strength Characteristics

Woven geotextiles are primarily manufactured from synthetic polymers, each offering distinct advantages:

Road Construction

In road construction, woven geotextiles play a critical role in enhancing the longevity and structural integrity of pavements. They are strategically installed between the subgrade (natural soil layer) and the aggregate base course to prevent the intermixing of fine-grained soils with coarse construction materials. This separation function maintains load-bearing capacity and prevents premature road failure.

Beyond separation, these fabrics significantly improve drainage by allowing water to pass laterally through the fabric while blocking soil particles. This reduces hydrostatic pressure, minimizes water accumulation in the subgrade, and mitigates risks of frost heave, erosion, and cracking—especially in regions with high rainfall or poor soil conditions.

By reinforcing weak subgrades, woven geotextiles also reduce the required thickness of aggregate layers, leading to material savings and lower construction costs. Their use is particularly beneficial in rural roads, highways, and temporary access roads over soft or unstable ground.

Landfill Projects

In landfill engineering, woven geotextiles are integral to both the lining and capping systems. As part of the liner, they act as a separation layer between the compacted clay or geomembrane liner and the protective soil cover, ensuring long-term stability and preventing punctures.

They are also crucial in leachate collection systems, where they allow contaminated water (leachate) to flow freely through drainage aggregates while filtering out fine sediments that could clog pipes. This ensures efficient leachate management and protects groundwater from pollution.

In landfill closure systems, geotextiles are used in landfill covers to manage stormwater runoff. Installed beneath soil and vegetation layers, they promote drainage, reduce erosion, and support slope stability. Their UV resistance and chemical inertness make them ideal for long-term exposure to harsh landfill environments.

Coastal Engineering

Coastal protection projects rely heavily on woven geotextiles for erosion control and habitat preservation. They are commonly placed beneath seawalls, breakwaters, and riprap (rock armor) as a filtration layer that prevents soil loss while allowing tidal water to pass through.

This dual function of filtration and reinforcement is essential in maintaining the structural integrity of coastal defenses. Without geotextiles, wave action can wash away underlying soil, leading to collapse of protective structures.

Additionally, woven geotextiles are used in innovative solutions such as revetments and geotextile tubes or bags. Filled with sand or slurry, these containers form artificial berms or reefs that stabilize shorelines, promote sediment deposition, and create habitats for marine organisms. Their durability in saline environments makes them ideal for long-term coastal resilience projects.

Mining and Dewatering

In the mining sector, woven geotextiles are extensively used for dewatering and sediment control. They are employed in dewatering screens, filter socks, and containment ponds to separate water from mineral slurries, tailings, and overburden.

By enabling rapid water drainage while retaining solids, these fabrics improve the efficiency of mineral processing and reduce the volume of waste requiring disposal. This not only enhances operational efficiency but also lowers transportation and storage costs.

Furthermore, woven geotextiles are critical in managing stormwater runoff from mining sites. Installed in silt fences, drainage ditches, and retention basins, they prevent fine sediments from entering nearby rivers, lakes, and wetlands—helping mining operations comply with environmental regulations and reduce ecological impact.

Expert Tip: When selecting a woven geotextile, always match the fabric’s specifications—such as tensile strength, permittivity, and aperture size—to the specific soil and hydraulic conditions of your project. Consulting with a geotechnical engineer ensures optimal performance and compliance with local standards.
