The 12-ounce non-woven geotextile, commonly referred to in metric units as the 400 g/m² non-woven geotextile, is one of the most widely used medium-weight needle-punched non-woven fabrics in civil and geotechnical engineering. This specification achieves an optimal balance between performance and cost, making it suitable for a variety of applications, from standard projects to those with moderately demanding requirements.

Performance

Physical Properties:
- High Strength: The 12 Oz Nonwoven Geotextile Fabric exhibits high tensile strength and elongation in both machine and cross-machine directions, allowing it to accommodate subgrade settlement and construction loads.
- Good Toughness: The needle-punched process creates a bulky, elastic structure with high puncture resistance and the ability to withstand dynamic loads.
Hydraulic Properties:
- High Permeability: The porous, three-dimensional fiber structure allows water to flow through freely while effectively retaining soil particles to prevent clogging.
- Filtration Function: The 12 Oz Nonwoven Geotextile Fabric allows water passage while preventing the intermixing of soils from either side, maintaining soil structure stability.
Durability:
- Corrosion Resistance: Chemically inert, offering good resistance to soil, water, and most chemicals.
- Aging Resistance: UV stabilizers can be added during production to extend service life when exposed to sunlight.
Separation Function:
- The 12 Oz Nonwoven Geotextile Fabric effectively prevents the intermixing of dissimilar soil layers (e.g., sub-base and soft subgrade), preserving their individual design functions.

Application

12-ounce non-woven geotextile is widely used in the following engineering fields:

Separation: Between the base course and soft subgrade in roads, railways, and airport runways to prevent aggregate from penetrating into the soft soil, maintaining layer thickness and bearing capacity.
Filtration and Drainage:
- Wrapping for drainage layers in road shoulders, retaining walls, and slopes to prevent clogging of pipes or aggregate.
- Filter layer in leachate collection and removal systems in landfills and tailings dams.
Protection:
- As a cushion layer under revetments and riprap for riverbanks and coastal protection to prevent erosion and cushion impacts.
- The 12 Oz Nonwoven Geotextile Fabric is used as a protective layer for geomembranes in composite systems.
Other Engineering Uses: Tunnels, subsurface drainage, landscaping, etc.
