Product Description

Short Nonwoven Geotextile Geofabric Road Highway Railway Landfill Construction

 

Product Description:

 

Zhongloo offers a full line of civil and environmental nonwoven geotextiles with weights up to 32 oz/sy. Nonwoven geotextiles are multi-purpose fabrics that are felt-like in appearance. The main functions for these products are filtration and separation.

The most common nonwoven is a needle-punched product. Staple fibers or continuous filaments are bonded by mechanically entangling the fibers with barbed needles. It looks and feels like black felt. Occasionally, the product will be manufactured in white or orange. Orange nonwovens serve as a warning barrier indicating contaminated soils.

Another method of manufacturing nonwoven geotextiles is spunbonding. During this process extruded filaments are spun onto a collecting belt and bonded by applying heated rolls. It results in a smoother and stiffer product with reduced pore size and increased strength. Spunbond products are usually gray in color.

Nonwoven filtration examples include wrapping geotextile around a pipe or enclosing stone with a geotextile to create a system that allows water to pass, but keeps soil from infiltrating and clogging the system. These are often referred to as French drains. Nonwoven drainage fabrics are an economical alternative to graded aggregate and sand filters and can eliminate many of the problems associated with using, purchasing and transporting aggregate.

Nonwovens can also be used in separation applications. These include paver patios or walkways; outdoor areas where cows or horses exercise to prevent mud; stream crossings in light traffic areas; under playground mulch; or for park-on/drive-on applications in wet areas. AREMA recommends heavy weight nonwovens as separators under railroad ballast.

Another use for a nonwoven geotextile is as asphalt overlay fabric. Overlay fabric increases pavement life by eliminating water intrusion and increasing pavement flexibility. Environmental grade, or M.A.R.V. weight nonwovens perform the critical task of protecting impermeable liners in public and private landfills.

Application:

1. Stabilization In stabilization, the fabric is applied on top of a material that is highly compressible. Most often, this material is wet, soft soil. Here, the geotextile allows water to seep from the soft soil to draining material. As a result, it consolidates the basement layer, thus strengthening it and making it a more trustworthy base.
2. Separation Fabric is laid between two layers of different materials, such as two different soil types, new construction, and soil, or new and old pavement. Separation is sometimes used interchangeably with stabilization, but there are fine distinctions.
3. Filtration Using geotextile infiltration is similar to using in stabilization. The main aim in both cases is to allow the passage of water from the covered layer. The goal of this application is to remove water while preventing soil and or any other fine particles from passing through. This is achieved in combination with a filter behind the geotextile. In this process, water is removed, rather than being filtered into a different material.
4. Moisture Barrier This application is almost the direct opposite of the above applications. In the moisture barrier, the geotextile is used to block water rather than allowing water to pass through. This is accomplished by applying an asphaltic suspension. As a result, the fabric becomes impermeable and suitable for use in construction projects such as pavement rehabilitation.
5. Drainage Geotextile material can help gather water or gas and then transport it along its plane, therefore providing seamless transmission. This process is what is traditionally called drainage function, which can be highly effective in chimney drains as well as drip drains.
6. Reinforcement In reinforcement, the geotextile acts as a source of strength instead of strengthening the bottom layer like in stabilization.
