Black Long Fiber Geotextile High Tensile Strength and Puncture Resistance for Building Structures

Product Introduction

Black long fiber geotechnical fabric is a type of geotechnical fabric. Geotechnical fabric, also known as geotechnical fabric, is a synthetic fiber material made by needling or weaving, presenting as a cloth-like product. Black long fiber geotechnical fabric is the type that is black in color and manufactured using long fibers. Its unit weight typically falls between 100 and 800 grams, with widths ranging from 1 to 6 meters and lengths varying from 50 to 100 meters.

Product Properties

 Mechanical Properties

• High Tensile Strength: Due to the characteristics of long fibers, black long fiber geotechnical fabric maintains sufficient strength and elongation in both dry and wet conditions. It can withstand significant tension without easily breaking, enhancing the tensile strength and resistance to deformation of soil. This is highly beneficial for improving the stability of building structures. For example, in dike projects, it can effectively resist the tension caused by water level changes and other factors in the soil.

• Good puncture resistance: In application scenarios where it may be squeezed or punctured by sharp objects, such as when laying in soil layers with sharp objects like stones, its good puncture resistance can protect the internal structure from damage. For example, when laying in the base layer of a road, it can prevent being punctured by stones in the base layer.

• Physical performance aspects

• Good breathability and water permeability: This allows water to pass through the geotechnical fabric, effectively trapping sand and soil loss, while also forming drainage channels within the soil structure to discharge excess liquids and gases, such as in soil areas with inadequate drainage systems. It helps to drain water and maintain the stability of the soil, preventing waterlogging from damaging the soil structure.

• Good Light Resistance: In particular, black long fiber geotechnical fabric made of polyester long fibers has excellent heat resistance and light resistance, can adapt to the outdoor use environment exposed for a long time, is not easy to age rapidly due to sunlight, and can be widely used in various outdoor projects such as highway, railway, etc. construction and maintenance.

• Corrosion Resistance: Able to withstand corrosion for an extended period in soil and water with varying acidity and alkalinity levels. Whether it's an acidic or alkaline soil environment, or engineering projects near polluted water bodies, it can function normally to ensure the durability of the project.

Product Application

1. The filtration of dam and slope protection, the isolation and seepage prevention of channel;
