The 4-ounce non-woven geotextile, commonly referred to in metric units as a 135 gsm non-woven geotextile, is a needle-punched non-woven geosynthetic material with a mass per unit area of 4 ounces (approximately 135 grams). As one of the most widely used basic geotextiles in civil engineering, it plays an indispensable role in filtration, separation, protection, and drainage applications, thanks to its excellent physical properties, strong cost-performance ratio, and mature manufacturing process.

Performance

Physical Properties of 4 oz Nonwoven Geotextile Fabric:

Mass Per Unit Area: 135 g/m² (±5%), conforming to the nominal weight and ensuring uniformity in engineering design.
Thickness: Typically ≥ 2.0 mm (under 2 kPa pressure). Its fluffy structure provides excellent water conductivity and cushioning capacity.

Mechanical Properties of 4 oz Nonwoven Geotextile Fabric:

Tensile Strength: Machine Direction ≥ 7.5 kN/m, Cross Machine Direction ≥ 6.5 kN/m. It possesses sufficient tensile strength to withstand various loads during construction and service.
Elongation at Break: 40% ~ 80%. It exhibits good deformation adaptability, allowing it to work in coordination with the soil.
CBR Puncture Resistance: ≥ 1.2 kN. It offers strong resistance to penetration by localized concentrated loads, such as sharp stones.
Tear Strength: Machine Direction ≥ 0.24 kN, Cross Machine Direction ≥ 0.20 kN. It effectively inhibits the propagation of tears from any initial damage.

Hydraulic Properties of 4 oz Nonwoven Geotextile Fabric:

Permeability Coefficient (Normal to Plane): ≥ 1.0×10⁻¹ cm/s (equivalent to Kv ≥ 1.0×10⁻² m/s). It offers excellent water permeability, facilitating the timely drainage of excess water from the soil mass.
Apparent Opening Size (O₉₀): 0.07 ~ 0.12 mm. It effectively prevents excessive soil particle loss while allowing water passage, achieving the “soil retention and water drainage” filtration function.

Durability of 4 oz Nonwoven Geotextile Fabric:

Acid and Alkali Resistance: Both polyester and polypropylene materials offer good chemical corrosion resistance, enabling them to adapt to various complex soil environments.
UV Resistance: The incorporation of UV stabilizers in the raw materials provides a certain level of anti-aging performance, allowing for outdoor storage for a period before being covered.

Application

The 4 oz nonwoven geotextile fabric is primarily used in engineering scenarios with moderate requirements for strength and thickness:

Separation: Used in projects such as road bases, playgrounds, and parking lots to separate soil layers of different properties (e.g., fill material from soft subgrade). This prevents their intermixing and maintains the integrity and load-bearing capacity of the structural layers.
Filtration: Applied in highway shoulder drainage, behind retaining walls, and in sports field French drains. It wraps drainage pipes or gravel drainage layers, allowing water to flow freely while effectively preventing soil particles from being washed away.
Protection: The 4 oz nonwoven geotextile fabric serves as a protective cushion for HDPE geomembranes in landfills, artificial lakes, and channels, preventing the membrane from being punctured by overlying or underlying materials.
Reinforcement: Used in lightly sloped reinforced soil structures or as a basal layer in vegetative slope protection, providing initial reinforcement and stabilization.
