NON WOVEN GEOTEXTILES
NON WOVEN GEOTEXTILES FOR COST-EFFECTIVE PROJECTS
FROM LIGHT-WEIGHT TO ULTRA HEAVY-WEIGHT
Non-woven geotextiles are a type of fabric widely used in construction and engineering applications. These materials are composed of synthetic fibers, such as polypropylene, or polyester, that are bonded together through various methods, including needle-punching and heat-setting, to form a continuous, cohesive fabric. One notable variation of these geotextiles includes the use of orange demarcation fabrics. These fabrics can be orange and printed with the warning “Danger do not dig”, making them useful for marking hazardous or cautionary areas. Unlike woven geotextiles, non-woven fabrics do not have a distinct, interconnected pattern of fibers, resulting in a more uniform and flexible material.
Non-woven geotextiles, including those with orange demarcation indicators, offer excellent filtration, drainage, and separation properties, making them well-suited for a range of applications. Regardless, these geotextiles are highly versatile and customizable, with variations available in fabric weight, thickness, and pore size to meet the specific requirements of different projects. Easy to install and cost-effective, non-woven geotextiles provide a robust solution for enhancing the performance and durability of various construction and engineering initiatives. Periodic inspection and maintenance can help ensure their long-term effectiveness in promoting stability and preventing erosion.

Specifications: Non Woven geotextiles are available in a variety of weights including Light-Weight (3 – 5 oz with roll widths of 12.5′ and 15′), Medium-Weight (6 – 8 oz with roll width of 15′), Heavy-Weight (10 oz/sy – 16 oz/sy) and Ultra Heavy-Weight (up to 100 oz/sy with roll widths up to 25′
FREQUENTLY ASKED QUESTIONS
NON WOVEN GEOTEXTILES
What are non woven geotextiles?
Non-woven geotextiles are fabric-like materials made from synthetic fibers, such as polypropylene, polyester, or polyethylene. These fibers are bonded together through various methods, including heat, chemicals, or needle-punching, to create a uniform, flexible material.
How do non-woven geotextiles differ from woven geotextiles?
Unlike woven geotextiles, which are made by interlacing fibers in a specific pattern, non-woven geotextiles are composed of randomly oriented fibers bonded together. As a result, non-woven geotextiles typically have higher flexibility, permeability, and conformability compared to their woven counterparts
What are the applications of non-woven geotextiles?
Non-woven geotextiles are used in a wide range of applications, including road construction, erosion control, sediment control, drainage systems, landfill liners, waste containment, railroad stabilization, embankment stabilization, retaining wall filtration, soil separation, pond liners, tunnel liners, subsurface bioretention systems, revetment systems, agriculture, horticulture, sports fields, mining, green roofs, pipelines, and airports.
How are non-woven geotextiles installed?
Non-woven geotextiles are typically rolled out and placed directly on the prepared surface, with overlapping edges to ensure continuous coverage. The geotextiles may be anchored or secured in place using stakes, pins, or other anchoring methods. The installation process may vary depending on the specific application and project requirements.
How long do non-woven geotextiles last?
The lifespan of non-woven geotextiles depends on factors such as the material, installation, environmental conditions, and maintenance. Properly installed and maintained geotextiles can last for several years, providing long-term stability and protection in various applications.
Are non-woven geotextiles environmentally friendly?
Non-woven geotextiles can contribute to environmental protection by preventing erosion, filtering pollutants from stormwater runoff, and containing waste materials. However, like any synthetic material, their production and disposal can have environmental impacts. It is important to consider the full life cycle of the product and choose geotextiles that meet environmental standards and regulations.
