Product Details

PP woven polypropylene geotextile separation fabric is a type of geotextile material made from woven polypropylene fibers. It is designed to provide separation and stabilization functions in civil engineering and construction projects. The fabric is made from polypropylene, a synthetic polymer known for its high strength and durability. The polypropylene fibers are woven together to form a stable and robust fabric.

PP woven polypropylene geotextile separation fabric acts as a separator between different soil layers or materials with different properties. It prevents the mixing or intermixing of these materials, maintaining their individual characteristics and enhancing the overall stability of the project.The fabric provides stabilization by distributing loads and reducing the potential for differential settlement. It helps to reinforce weak soils and improve their load-bearing capacity.While PP woven geotextile separation fabric primarily serves as a separator, it also has some filtration properties. It allows water to pass through while preventing the migration of fine particles. This helps in maintaining the integrity of the soil structure and preventing clogging of underlying drainage systems.

PP woven polypropylene geotextile separation fabric finds applications in a wide range of civil engineering projects, including road construction, railways, embankments, retaining walls, and landfills. It is commonly used as a separation layer between subsoil and aggregate or other materials, preventing the mixing of different layers and enhancing the stability of the structure.

The fabric can be used in erosion control applications to stabilize slopes, embankments, and shorelines. It helps to prevent soil erosion by providing a stable barrier between different soil layers.

While PP woven polypropylene geotextile separation fabric is primarily used for separation and stabilization purposes, it has limited drainage capabilities. If effective drainage is a critical requirement for the project, additional drainage materials or systems may be needed.

1. What Is PP Woven Polypropylene Geotextile Fabric?

PP woven geotextile fabric is a synthetic textile made from high-tenacity polypropylene (PP) slit film yarns, woven in a crisscross pattern to form a strong, permeable layer. It is designed to provide mechanical separation, load distribution, and filtration between different soil layers in civil engineering and environmental projects.

📌 Primary Attributes: High tensile strength, low elongation, chemical resistance, dimensional stability, and UV resistance.

2. Core Engineering Functions

PP woven geotextile separation fabric delivers the following core geotechnical functions:

Separation: Prevents intermixing of dissimilar materials, such as base aggregate and subgrade soil.
Reinforcement: Enhances the structural integrity of soil, reducing deformation under load.
Filtration: Allows water to pass while retaining soil particles.
Drainage: Facilitates lateral water movement within the fabric plane.
Erosion Control: Protects slopes and embankments from surface erosion.

3. Material Composition and Manufacturing Process

Material:

Polypropylene (PP): Chosen for its high strength-to-weight ratio, resistance to acid, alkali, and biological degradation, and low water absorption.

Manufacturing:

Slit-film extrusion → Yarn weaving → Heat setting → Roll finishing
Weight range: 70 to 400 gsm (grams per square meter)
Color: Typically black or white (UV-stabilized variants)

4. Key Performance Specifications

Parameter	Typical Values	Notes
Tensile Strength (MD/CD)	≥ 20–100 kN/m	As per ASTM D4595 / ISO 10319
Elongation at Break	< 15%	Indicates stiffness and reinforcement
Apparent Opening Size (AOS)	0.15 – 0.60 mm	Controls particle retention
