PRODUCT DETAILS
Product Overview: Geotextiles Designed for Efficient Drainage and Filtration
Our highly permeable nonwoven geotextiles are indispensable professional materials in underground drainage system engineering. They are manufactured using high-quality polypropylene (PP) or polyester (PET) staple or filament fibers through a precision needle-punching process, resulting in a high-performance fabric with high porosity and a three-dimensional structure.
The core value of this geotextile lies in its high flow rate and superior filtration function. It allows water to flow rapidly while effectively trapping fine soil particles, preventing drainage channels or blind drains from being blocked by silt, ensuring the continuous and efficient drainage of groundwater and surface runoff.
Key Advantages: Ensuring Long-Term Stability of Drainage Systems
In projects requiring groundwater control and soil erosion prevention, selecting geotextiles with high permeability and excellent filtration properties is crucial.
High Permittivity: This product boasts an extremely high permeability coefficient, enabling instantaneous response to changes in water pressure and ensuring rapid drainage. This is critical for projects in areas with heavy rainfall or high groundwater levels, effectively preventing water accumulation within the structure.
Clog Resistance & Durable Filtration: The random distribution of nonwoven fibers forms a porous filter. Its apparent opening size (AOS) is precisely controlled, preserving the surrounding soil structure while preventing the entry of fine particles, thus maintaining a long-term, stable filtration effect and extending the service life of the drainage system.
High Strength and Durability: Despite its focus on permeability, this geotextile possesses sufficient tensile and puncture strength to withstand the backfill pressure of aggregates during construction and daily operational stresses, making it easy to lay and resistant to damage.
Multifunctional water conduction capability: In addition to vertical infiltration, its thickness provides planar water conduction capability, which also helps to guide water flow to the preset drainage outlet, improving the overall drainage efficiency of the system.
Detailed parameter table: Key indicators of drainage reverse filtration performance
The following are typical specifications and key performance indicators for the application of high-permeability geotextiles in underground drainage systems:
| Property | Test Method | Unit | High Permeability Range |
|---|---|---|---|
| Permittivity | ASTM D4491 | sec⁻¹ | $\ge 1.0$ |
| Apparent opening size (AOS) | ASTM D4751 | mm (or US Sieve) | 0.15 – 0.35 (40 – 100 Sieve) |
| Mass Per Unit Area | ASTM D5261 | g/m² | 150 – 300 |
| CBR Puncture | ASTM D6241 | N | 1,500 – 3,500 |
| Grab Tensile | ASTM D4632 | N | 1,000 – 2,000 |
| Material | - | - | PP/PET staple fiber or filament |
Note: For high-permeability products, special attention should be paid to the permeability coefficient (Permittivity) and apparent opening size (AOS).
Typical Application Scenarios: Achieving Efficient Water Management
Our high-permeability filter geotextiles are ideal for all engineering projects requiring separation, filtration, and drainage, including:
French Drains/Trench Drains: As a core filter layer, they wrap around the water-collecting aggregate to prevent soil from entering drain pipes or gravel layers.
Retaining Wall and Abutment Backfill Drainage: Laid between the backfill material and the original soil behind the retaining wall, acting as a filter layer to ensure the release of backfill pressure while preventing soil loss behind the wall.
Sports Field and Artificial Landscape Drainage: Used in football fields, golf courses, and artificial turf bases to accelerate the drainage of accumulated water, maintaining site dryness and usability.
Road and Railway Subgrade Drainage: Used under railway ballast layers or in transverse drainage systems of highway subgrades to prevent fine soil upwelling and accelerate water removal, improving subgrade stability.
