With advancements, our woven and non-woven geotextile fabrics have changed the way of execution and the utilization in various applications.
Our geo fabrics offer useful, simple and cost-effective solutions for improving the performance of majority construction application be it pavement or soil.
Geotextile is typically defined as any permeable textile material used to increase soil stability, provide erosion control or aid in drainage. Our polymers and manufacturing processes result in an array of geotextiles suitable for a variety of civil construction applications.
Geotextiles provide strength and durability by separating a foundation or construction from underlying soil. For example, if pavement is laid on dirt, over time the lowest layer of the pavement will disassociate as the soil infiltrates the pavement. This leads to weaker pavement, reduced service life and greater maintenance costs.
Using a geotextile layer to separate the pavement from the ground helps maintain the structural integrity of the pavement over time. This is especially important in climates that undergo successive episodes of freezing and thawing. Geotextiles also help prevent the underlying soil from contamination, as well as the pavement from settling if the subgrade beneath the pavement sinks or shifts.
Specifically, woven geotextile fabrics are manufactured by weaving narrow strips of film together to form one large piece. This results in a tough fabric that has a higher load capacity. That’s why woven geotextiles are used commonly for ground stabilization in roadway construction projects.
Geotextiles are used most frequently in filtration. Water or another fluid flows through the geotextile, and particles that are larger than the size of the weave are trapped by the geotextile. The concern in filtration applications is that the geotextile will eventually become clogged and will need to be replaced over time.
In drainage applications, geotextiles can facilitate the movement of liquids. Here, non-woven geotextiles are preferred. They’re designed typically for short-term applications to wick or otherwise drain liquids from a particular area.
Geotextiles also offer erosion control solutions – they’re often used to firm up soil surfaces. The geotextile can help protect the surface from the eroding effects of wind and rain. It can also help reinforce soil, for example, along embankments that would otherwise face a greater likelihood of erosion and degradation.
This is becoming increasingly important in shoreline and close-to-shore installations. Geotextiles can help guard against wave erosion and have been used in Australia, Germany, the United Kingdom and the USA.
Geotextiles can also help provide a barrier to moisture when other chemicals are added to their composition. This application – often used in paving – reduces the amount of water that gets below the pavement and into the foundation or subgrade.
In addition, geotextiles can provide a filter fence – which when reinforced is known as a super silt fence – to protect streams, rivers, lakes or other bodies of water from runoff sediment that would otherwise contaminate the water source.
You’ll find geotextiles used in underground stabilization under railroad tracks, underground drainage providing a foundation for pipes and pillars, embankment protection, seawalls, bridge abutments, sports fields and numerous other situations.
Now, geotextiles are beginning to benefit from the embedding of fiber optics. This offers real-time situational awareness of the installation. With advanced monitoring, engineers can better anticipate when preventive or proactive maintenance may be required.
Non-woven geotextiles resemble felt and provide planar water flow. They are commonly known as filter fabrics, although woven monofilament geotextiles can also be referred to as filter fabrics. Typical applications for non-woven geotextiles include aggregate drains, asphalt pavement overlays and erosion control.
A woven geotextile is a planar textile structure produced by interlacing two or more sets of strands at right angles. There are two types of strands: slit films, which are flat; and monofilaments, which are round. Woven slit-film geotextiles are generally preferred for applications where high strength properties are needed and filtration requirements are less critical. These fabrics reduce localized shear failure in weak subsoil conditions and aid construction over soft subsoils. Woven monofilament geotextiles are preferred for applications where both strength and filtration are a concern, such as shoreline rip rap applications.
Geotextile-related materials such as fabrics formed into mats, webs, nets, grids, or formed plastic sheets are not the same as geotextiles. These would fall under the more general category of geosynthetics
