Material Functions
One Layer, Four Essential Roles
Geotextile selection starts with the required function, subgrade condition, water movement, installation damage risk and design life. The correct structure and polymer are then matched to the project.
Reinforcement
Distributes loads and restrains lateral soil movement to improve structural stability.
Separation
Prevents aggregate and fine soil layers from mixing and preserves designed layer thickness.
Filtration
Allows water to pass while retaining soil particles and limiting internal erosion.
Дренаж
Creates a controlled path for pore water and helps reduce damaging water pressure.
01 / Transportation Infrastructure
Subgrade Reinforcement
Installed between road layers, geotextiles form a stable reinforcement and separation interface. They distribute traffic loads, restrict lateral movement and keep fine subgrade soil from contaminating the aggregate base. Their filtration and drainage performance also helps remove infiltrated water, reducing softening, pumping, frost-related damage and premature pavement distress.
Typical Project Challenges
- Low subgrade bearing capacity
- Aggregate and soil intermixing
- Water accumulation and pumping
- Reflective pavement cracking

02 / Ground Improvement
Soft Ground Treatment
Soft foundations combine high water content, low bearing capacity and settlement risk. A geotextile layer spreads construction loads, limits lateral soil displacement and separates weak subsoil from granular fill. By allowing pore water to escape while retaining soil particles, the system supports consolidation and helps maintain the integrity of each engineered layer during construction and service.
Typical Project Challenges
- High water content
- Low bearing capacity
- Uneven settlement
- Loss of aggregate into soft soil

03 / Waste Containment
Landfill
In landfill liner systems, woven geofilters work with HDPE geomembranes, drainage geonets and gravel layers. The geotextile allows leachate to reach the collection system while retaining fine particles that could obstruct drainage paths. Positioned next to the geomembrane, it also provides separation and cushion protection against stones and waste fragments, helping preserve the integrity of the containment system.
Typical Project Challenges
- Fine-particle migration
- Drainage layer clogging
- Geomembrane puncture risk
- Slope layer instability

04 / Hydraulic Engineering
Slope and Riverbank Protection Engineering
Placed between natural soil and revetment materials, geotextiles provide a permeable filter that releases water while retaining the bank soil. This reduces seepage pressure, limits piping and soil loss, and stabilizes the slope beneath stone, gabion, ecological or concrete protection systems. Suitable products are selected for long-term immersion, wet-dry cycling and installation damage exposure.
Typical Project Challenges
- Flow and wave erosion
- Soil loss beneath revetment
- Seepage pressure and piping
- Wet-dry exposure cycles

05 / Load Transfer Platforms
Reinforcement Layer for Pile‑Supported Structure
Within pile-supported embankments and load-transfer platforms, geotextiles distribute concentrated loads between pile heads and the surrounding soil. The reinforcement layer restrains lateral movement, helps control differential settlement and keeps granular platform material separated from fine backfill. Filtration and drainage performance also helps maintain a dense, stable working layer above the foundation system.
Typical Project Challenges
- Concentrated pile-head loads
- Differential settlement
- Lateral fill deformation
- Granular cushion contamination

06 / Earth-Retaining Structures
Reinforced Soil Retaining Wall
Installed horizontally between compacted fill layers, woven geotextiles create a reinforced soil mass that resists lateral displacement and earth pressure. The system supports reinforced slopes, stepped walls and vertical retaining structures while providing separation, filtration and drainage. Correct tensile strength, anchorage length and installation spacing are determined from the structural design and site conditions.
Typical Project Challenges
- Slope instability and sliding
- Lateral earth pressure
- Water pressure behind walls
- Fill loss and internal erosion

Product Selection
Woven or Nonwoven?
Both structures can separate and filter, but their strength, elongation, opening size and hydraulic behavior differ. Final selection should follow the project design criteria and required test values.
