The 16-ounce non-woven geotextile is a heavy-weight, needle-punched non-woven geosynthetic material with a unit area mass of 16 ounces per square yard (approximately 542 g/m²). Known for its excellent physical and mechanical properties, good water permeability, and aging resistance, it is a key material in civil and geotechnical engineering used for reinforcement, separation, filtration, drainage, and protection. Due to its high mass per unit area and thickness, it is particularly suitable for heavy-duty engineering applications that require high strength and robust protective capabilities.
Performance
High Strength: As a high grammage product, 16 Oz Nonwoven Geotextile Fabric possesses high tensile strength and tear strength in both machine and cross-machine directions, effectively distributing and withstanding stresses from soil and external loads for reinforcement and stabilization.
Excellent Filtration and Drainage: Its three-dimensional fibrous network allows water to pass through freely while effectively preventing the excessive migration of soil particles, preventing piping, and maintaining soil structure stability.
Separation Function: When installed between two dissimilar materials (e.g., aggregate and soft subgrade), it prevents them from mixing, preserving the integrity and function of each layer.
Good Elongation and Deformation Adaptability: Needle-punched geotextiles possess a degree of elongation, allowing them to accommodate uneven settlement and deformation of the foundation without brittle failure.
Chemical Resistance: Polypropylene material offers good resistance to most acids, alkalis, salts, and microorganisms, making it suitable for various harsh soil and groundwater environments.
UV Resistance: UV stabilizers are typically added during manufacturing to extend service life when exposed to sunlight. However, covering for long-term exposure is recommended.
Water Permeability: The 16 Oz Nonwoven Geotextile Fabric is a permeable material with good transmissivity perpendicular to the plane of the geotextile.
Application
Given its heavy-duty nature, the 16-ounce non-woven geotextile is primarily used in engineering fields demanding high strength and durability:
Highway & Railway Subgrade: Used in soft ground improvement as a reinforcement and separation layer to prevent pavement pumping and settlement.
Landfills & Tailing Dams:
Acts as a protection layer for the bottom liner system, preventing puncture from overlying gravel or geomembranes.
Serves as a filter layer in leachate collection and gas venting systems.
Riverbank, Coastal & Reservoir Slope Protection: Installed beneath riprap or concrete blocks as a filter layer to prevent soil erosion.
Large Site Foundations & Airport Runways: Used for subgrade stabilization and separation to enhance load-bearing capacity.
Tunnels & Underground Engineering: The 16-ounce non-woven geotextile is used for drainage and cushioning behind waterproofing layers.
