Geotextile Separation Fabric for Roads, Railways & Landscapes
Choosing the Right Geotextile Separation Fabric for Roads, Railways and Landscaping Applications
TERRAPRO Geotextiles
TERRAPRO Geotextiles are nonwoven geotextile manufactured using advanced bico technology from UV stabilized virgin polyolefin that have been thermally bonded to provide high mechanical strength and excellent hydraulic characteristics. TERRAPRO Geotextiles are nonwoven geotextiles and extensively used in stabilisation and drainage applications to provide separation and filtration functions, preventing the intermixing of granular layers and the ingress of fines. Their use ensures an improved performance and design life of granular layers.
Functions of TERRAPRO Geotextiles:
TERRAPRO Geotextiles serve multiple roles depending on where and how they are used. The primary functions include:
- Filtration: Allows water to pass through while retaining soil particles, preventing clogging and soil migration. Example: Used behind retaining walls or beneath drainage layers.
- Separation: Prevents mixing of different soil layers, such as subgrade and base material in roads, ensuring structural stability.
- Drainage: Provides an efficient pathway for water movement, enabling proper subsurface drainage in roads, embankments and retaining structures.
- Protection: Acts as a cushioning layer for geomembranes in landfill and pond liner systems, protecting them from puncture or damage caused by sharp objects.
Key Benefits of TERRAPRO Geotextiles:
TERRAPRO Geotextiles provide multiple benefits while installed in civil projects. Core benefits include:
- Excellent Filtration and Permeability – The porous structure of nonwoven geotextiles allows free water flow while retaining fine soil particles. This balance is critical in preventing clogging and ensuring long-term drainage performance.
- High Durability – Nonwoven fabrics are resistant to chemical degradation, UV exposure and biological attack, ensuring long service life even in harsh environments.
- Cost-Effective and Easy to Install – Lightweight and flexible, nonwoven geotextiles are easy to handle, transport and install — reducing construction time and overall project costs.
- Versatile Applications – From highways and railways to landfills and coastal protection, nonwoven geotextiles are used in almost every area of infrastructure development.
- Environmental Sustainability – By enhancing soil stability, reducing the use of natural aggregates and promoting effective drainage, nonwoven geotextiles support sustainable engineering practices.
Applications of TERRAPRO Standard Geotextiles
TERRAPRO Geotextiles being used for diverse applications into various markets. The primary sectorial applications include:
- Road Construction – To separate subgrade from aggregates, prevent rutting and improve pavement life.
- Railway Tracks – For separation and filtration under ballast, improving stability and drainage.
- Landfill Liners and Capping Systems – As a protection and filtration layer for geomembranes, ensuring safe containment of waste.
- Drainage Systems – In subsurface and edge drains, allowing efficient water flow while preventing soil migration.
- Embankments and Slopes – For erosion control and filtration in soil-retaining structures.
- Canals, Ponds and Reservoirs – To protect liners and maintain soil integrity around hydraulic structures.
- Landscaping – Being used for many applications in landscape industry for separation and filtration application even in root control and weed suppression applications
Choosing the Right Nonwoven Geotextile:
Selecting the right TERRAPRO Geosynthetics depends on project requirements for below important technical criteria such as:
- Permeability and pore size (for filtration)
- Tensile strength and puncture resistance (for protection)
- Weight and thickness (for durability)
- Chemical resistance (for environmental compatibility)
