Geotextiles – Woven and Nonwoven
Geotextiles are often defined as; A permeable textile manufactured from polymeric material used with foundation, soil, rock or any other geotechnical engineering-related material as an integral part of, and to enhance the performance or cost of, a human-made product, structure, or system.
FX®-HS Nonwoven (Civil) Geotextiles – Considered multipurpose. This is due to the fact that they can offer immediate and cost-effective solutions for many separation, drainage, erosion control as well as filtration applications.
FX® Slit Film Geotextiles – Offer cost effective solutions for most separation and stabilization applications. They are commonly used in driveways, as well as both paved and unpaved roads.
FX®-MF High-Performance Geotextiles – Were developed to deliver the higher strengths and long-term performance that cannot be achieved by typical woven slit-film fabrics.

Carthage Orange Demarcation Geotextiles – Are essential in projects where a visual warning layer is necessary. Orange fabric is often used to prevent future excavation projects from causing damage, but also serves as a prompt for workers to stop digging.
Carthage %™ Open Area Woven Monofilament Geotextiles – Provide long-term solutions for nearly any drainage / filtration application. This product line also has special weave patterns and monofilament yarns that produce a high Percent Open Area (POA).
FX®-PET High-Strength Woven Polyester Geotextiles – Deliver the higher ultimate tensile strength properties. They are also resistant to installation damage, as well as offering exceptional creep resistance and soil interaction. This results in higher long-term design strengths (LTDS) per GRI-GT7.
Livestock Mud MatTM – Will separate your cover material from the mud below. This prevents the cover material from intermixing, but also evenly distributes weight. This prevents ‘ruts’ or ‘depressed areas’ that would negatively impact the health of the livestock.
Geotextiles: Types and Series by Function – This is a chart showing the different series of geotextile fabrics. It also shows what functions they typically serve such as separation, erosion protection, asphalt overlay, and many more.
Carthage FX®-A/O Asphalt Overlay Fabrics – Provide an economic solution to extending the useful life of pavement overlays. They also improve the performance of asphalt road surfacing and additionally resurfacing by up to 50%. They do this by reducing the “causes” of overlay fatigue failure.
More Information:
Although geotextiles are textiles in the traditional sense, because they consist of synthetic materials, biodegradation is not a problem. The fibers and/or yarns used in the manufacture of them are made from the following polymeric compounds, listed in order of decreasing use: polypropylene, polyester, polyamide, and polyethylene. However, the major point is they are porous to water flow both across and within their manufactured plane, but to a widely varying degree.
Classifications or Types
There are a seemingly endless combinations of polymers, yarns, fibers and manufacturing processes that produce the three major geotextile classifications: woven, nonwoven and – to a lesser degree – knitted. However, in general:
Woven Geotextiles
A woven geotextile consist of monofilament, multifilament, slit-film and/or fibrillated slit-film yarns – although often in combinations. They are woven into a geotextile on conventional textile weaving machinery using a wide variety of traditional, and also proprietary, weaving patterns. The variations are many and most have a direct influence on the physical, mechanical and hydraulic properties of the fabric. Therefore, the resulting woven geotextiles are typically flexible, exhibit high strength, high modulus, low elongation, and their openings are usually direct and predictable.
Nonwoven Geotextiles
Nonwoven geotextiles consist of fibers that are continuous filament or short staple fibers. These fibers are then bonded together by various processes that can include a needling process that intertwines the fibers physically (needlepunched). Additionally, a chemical / thermal bonding process that fuses adjacent fibers together can be used. The resulting nonwoven geotextiles have a random fiber orientation with high porosity and permeability, but also indirect and unpredictable openings, a thickness ranging from thick felt to a relatively thin fabric, and low modulus and high elongation (needlepunched).
