Polypropylene Woven Geotextile
Product Introduction
Geoleed High-Strength Woven Geotextile Series
Geoleed woven geotextiles are made from high-quality polypropylene (PP) or polyester (PET) industrial filaments/flat yarns, woven using a precise weaving process. Their tight structure and dimensional stability are specifically designed to solve reinforcement, isolation, and protection challenges in harsh engineering environments.
Ultra-High Strength Range: Offering a variety of strength options from 20kN/m to over 1000kN/m, meeting the needs of everything from ordinary rural roads to large port terminals.
Superior UV Resistance: In strong UV environments, we add a special ratio of antioxidants and carbon black to the raw materials to ensure the product maintains its mechanical properties for a long time even under intense sunlight exposure.
Corrosion Resistance and Long Service Life: Resistant to acids and alkalis, anti-aging, and unaffected by biodegradation, with a service life of over 50 years in complex chemical environments such as landfills and tailings.
Working Principle
1. Reinforcement: This is the most significant function of woven geotextiles.
High tensile modulus: The tightly packed warp and weft fibers of the woven fabric provide extremely high tensile strength.
Stress distribution: When laid on soft soil foundations, it restricts lateral displacement of the soil through friction and interlocking forces. When a load is applied from above, it acts like a "bundle," dispersing concentrated stress over a larger area, thereby increasing the bearing capacity of the foundation.
2. Separation: Prevents the mixing or loss of two materials with different properties.
Preventing layer mixing: In subgrade construction, woven geotextiles separate the underlying soft soil from the upper layer of crushed stone fill. Without this separation layer, the crushed stone would sink into the soil, while the soil would seep upwards, causing the subgrade to lose its support.
Maintaining structural integrity: Ensures that each layer of building material performs according to its designed physical properties.
3. Filtration & Drainage
While woven fabrics are generally less permeable than nonwoven fabrics (needle-punched nonwovens), they still possess specific hydraulic functions:
One-way permeability: Allows water to flow through the fabric surface while trapping soil particles.
Flat-plane drainage: Within the plane of the woven fabric, water can drain away along the gaps in the fabric, reducing pore water pressure within the soil and enhancing soil stability.
