Engineering the Earth: A Complete Guide to Geotextile Fabric

Geotextiles are one of the most important inventions of the 21st century, they are essential in all the disciplines of engineering including civil, environmental, and geotechnical. These are polymeric porous materials that are used in combination with materials such as soil or rocks. Their principal operation is to modify by means of a construction project the soil in the place. In this way, the geotextiles become a solution for the local drainage and ground stabilization problems which in the past could be only partially solved by conventional methods. Geotextiles, by utilizing a layer of very carefully designed material, change the mechanical properties of the soil and thus they supply there where it is most needed, strength, filtration, and separation. These textile fabrics, due to their wide range of applications, today are quite essential in the development of the infrastructure of the modern world, namely in building from a strong road system to the protection of the earth and the intelligent management of water resources.

Types of Geotextile Fabric

Geotextile fabrics mainly refer to two basic categories: woven and non-woven. The characteristics, as well as the structure, physical properties, and functions, differ for each type.

Woven Geotextiles are the ones that are made by weaving monofilament or slit film yarns that run parallel to each other just like the procedure in producing the traditional cloth. The fabric which comes from this interwoven structure has very high tensile strength and is of low elongation (stretch), thus it can be used for reinforcement and separation applications. The main feature of them is the capability and the function in which they can be the interface, under heavy loading, for example when stabilizing the ground under roads and railway lines where weight distribution is of a great importance, they can distribute the load without bearing the brunt of the other ground under.

Non-woven Geotextiles are products that are made by bringing together synthetic fibers in random positions by means of mechanical, thermal or chemical processes, which result in a material that looks like felt. The major method is the needle-punching one, which connects the fibers and thus creates a strong, porous fabric. The random structure of fibers and high permeability raise the usefulness of a material in such applications as filtration, drainage, and protection. Non-woven geotextiles are the most common filter materials in drainage systems, they are used to protect geomembranes from puncture, or they are a separation layer that allows water to pass through easily.

Primary Uses and Applications

The basic features of geotextile fabric—separation, filtration, drainage, reinforcement, and protection—lead to a wide variety of applications in different industries. 

Separation is accomplished if the fabric is placed between two layers of soil or aggregate that have different particle sizes in order to stop them from mixing. For example, in road building, geotextile fabrics stop the soft soil under the road from moving into the aggregate base that is load-bearing, thus, the structural integrity and the durability of the pavement are being maintained.

Filtration is one of the main functions in drainage systems. The fabric serves as a filter that allows water to flow through it without any problems and at the same time keeps very small soil particles inside. This action also prevents the perforated pipes or granular layers from being clogged. For instance, non-woven geotextile fabric is usually fixed around a French drain to guarantee a sustainable drainage system.

Drainage is a technique of collecting and removing water that is within the plane of the geotextile. Usually, the water goes through the non-woven geotextile which is a thick item and is put behind retaining walls to relieve hydrostatic pressure buildup.

Reinforcement takes advantage of the fabric's tensile strength, especially with the woven types, to increase the mechanical properties of the soil mass. You can add more layers of geotextile in an embankment or a retaining wall to not only get more strength but also allow your project to have either steeper slopes or a higher load capacity.

Protection means putting a durable geotextile layer over a geomembrane that is an impermeable liner with the purpose of saving it from being damaged by sharp stones in the subgrade, which is the most common application in landfills and reservoirs.

Geotextiles in Specialized Fields

The use of geotextiles covers the specialized areas, giving proper solutions for the main problems.

Gardening, landscaping, and geo fabric has become one of the most common applications. When used beneath gravel paths or patios, these lightweight, non-woven fabrics can effectively separate the area without any visual impact, allowing the gravel to remain securely in place and preventing the soil from being compacted. In addition, they are also used for weed control, as water and nutrients can still reach the soil, while blocking the sunlight necessary for the growth of weeds. Moreover, in roof gardens and elevated planter boxes, geotextiles are used for essential separation and filtration of the drainage layer.

In construction, especially when dealing with underground or submerged structures, the use of Geotextile fabric for waterproofing is very necessary. Even though geotextiles are permeable by nature, they are still used as a protective layer or a cushion along with an impermeable geomembrane or waterproofing coating. This combination is what results in a strong and long-lasting barrier. For example, a high is used to ensure the protection of a waterproofing layer on tunnel liners or foundation walls from being punctured or damaged. Grams per Square Meter (GSM Geotextile) shows the weight and density of the fabric, which determines its strength especially its puncture resistance and also its durability. The products made by Singhal Industries Pvt Ltd are rated by their GSM and can be used to fulfill the toughest requirements of various projects.

Benefits of Using Geotextile Fabric

Geotextile technology adoption ushers in a wide range of benefits over traditional methods, which are mainly responsible for a decrease in construction costs and the extension of the lifespan of structures. The application of geotextiles will allow the use of different soil materials from the local areas hence reducing the demand for high-priced, imported aggregates. The installation of the products will be carried out with great ease and at a high speed which will save a lot of time and also reduce the labor on the site. By supplying excellent separation and filtration, they will uphold the standards of granule layers, stopping the occurrence of early structural failure thus lowering the possibility of servicing. Moreover, in many cases, the use of geotextiles may also be one of the environmentally friendly options as they can lower the need for the release of the earth, and are also highly efficient in managing erosion, thus, can be natural habitat-friendly.
