Different Types Of Geosynthetic Materials Available On The Market – Uses Of Geosynthetics

 

  • Geotextiles

Geotextiles are commonly used for erosion control. They are typically placed on slopes to help reduce the rate of erosion. Though their effectiveness can vary depending on the type of soil, slope, and rainfall, they can be a helpful tool in protecting against soil erosion. Geotextiles are made from synthetic materials, such as polypropylene or polyester, and act as a barrier between the soil and other materials, such as rocks or concrete. This barrier prevents the mixing of different materials and helps to stabilize the soil. In addition, geotextiles can help to reduce the amount of runoff by allowing water to seep through their pores. As a result, geotextiles can be an effective way to protect against soil erosion.

  • Geogrids

Geogrids are a type of geosynthetics that are often used in road construction. In the case of road construction, geogrids are used to reinforce the soil beneath the road surface. This helps to make the road stronger and less likely to collapse or crack over time. Geogrids are made from a variety of materials, including plastic, steel, and glass. They are typically produced in long rolls that can be cut to the desired length and width. Geogrids can also be used in a variety of applications, including retaining walls, slopes, and embankments. In many cases, they are used in conjunction with other geosynthetics, such as geotextiles or geomembranes.

  • Geomembranes

Geomembranes are frequently used in landfill engineering, as they can act as a barrier between the waste material and the surrounding environment. Geomembranes are typically made from high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE). They are usually colored to limit the amount of light penetrating the waste, which can help control leachate generation.

The most common type of geomembrane liner system is the extruded HDPE geomembrane liner, which is formed by extruding molten HDPE onto a cooling roll. This type of geomembrane has good chemical resistance and is less susceptible to punctures and tears. In most circumstances, geomembranes are also used in conjunction with other geosynthetic products, as they can provide additional strength and durability.

  • Geonets

Geonets are three-dimensional nets used to drain or separate soil or other materials. They are made from polymeric materials such as polyethylene or polypropylene and are available in a variety of pore sizes and strengths. Geonets are often used in drainage applications such as landfill leachate collection systems and French drains.

In a leachate collection system, for example, geonets are placed between the bottom liner and the soil to create a void space that collects leachate. The leachate is then channeled away from the waste material, preventing contamination of the surrounding environment. When used in a French drain, geonets help to increase the storage capacity of the drain by creating an additional void space for water to flow into. This can be especially helpful in areas with high rainfall or where groundwater levels are close to the surface. By helping to store and channel water, geonets can play an important role in protecting both the environment and human health.

Composite geosynthetics, also known as geocomposites, are a type of product that is made by combining the properties of multiple types of geosynthetics into one. This can be done by combining different geosynthetic materials(such as geomembranes and geotextiles), or by using different manufacturing processes to produce a single product.

Composite geosynthetics are often used in reinforcement applications, as they can provide better performance than traditional geosynthetics. For example, composite geosynthetics can be used to reinforce soil walls, slope stabilization, and landslide mitigation. In addition, composite geosynthetics can be used to improve the performance of pavement systems. Overall, composite geosynthetics offer many benefits and are an important tool for civil engineers and other professionals who work with geosynthetics.

  • Synthetic Turf Reinforcement Mats (STRM)

Synthetic turf reinforcement mats (STRM) are commonly used in sporting applications, as they can provide a durable surface for playing field sports such as football or soccer. STRM is made of synthetic materials, such as polypropylene or polyethylene, which are woven into a mat that can be laid over existing grass to provide extra strength and stability. The mats help to protect the grass from wear and tear, and also improve drainage.

In addition, STRM can be used to create temporary playing surfaces on unused land or car parks. This makes them an ideal solution for sporting clubs that need a durable, high-quality playing surface but may not have the budget for a full artificial pitch.

  • Erosion Control Products

Erosion control products are often used in landscaping applications, as they can prevent soil erosion due to rainfall or wind. There are a variety of these products available on the market, each of which has its own set of benefits and drawbacks. For example, one type of erosion control product is biodegradable netting. This type of product is designed to disintegrate over time, making it an environmentally friendly option.

However, biodegradable netting may not be as effective as other erosion control products in severely eroded areas. Another type of erosion control product is jute matting. Jute matting is made from natural fiber and is often used in conjunction with other types of products, such as coir logs, to provide maximum protection against erosion. Jute matting is also relatively easy to install, making it a popular choice for many homeowners. However, jute matting can be expensive, and it may not be the best option for large-scale projects.

  • Drainage Composites

Drainage composites are frequently used in drainage applications, as they can provide an effective way to remove water from an area without causing damage to the surrounding environment. There are a variety of different types of drainage composites available on the market, and each has its own advantages and disadvantages.

One of the most popular types of drainage composites is known as a geocomposite drainage blanket. Geocomposite drainage blankets consist of a layer of nonwoven fabric sandwiched between two layers of geotextile fabric. The nonwoven fabric helps to absorb water, while the geotextile fabric prevents soil particles from clogging the drains. Another type of drainage composite is known as a perforated drain pipe. Perforated drain pipes are made of a variety of materials, including PVC, HDPE, and polyethylene. The holes in the pipe allow water to enter, while the solid walls prevent soil particles from entering.

Perforated drain pipes are often used in conjunction with French drains or catch basins. French drains are typically installed around the perimeter of a structure, and they consist of a perforated pipe that is surrounded by gravel. Catch basins are similar to French drains, but they are typically installed in areas with a high water table.

When choosing a drainage composite for your application, it is important to consider the type of soil you have, as well as the amount of water that will be present. For example, if you have sandy soil, you may want to consider using a geocomposite drainage blanket. If you have clay soil, on the other hand, you may want to use a perforated drain pipe. No matter what type of drainage composite you choose, it is important to install it properly in order to ensure that it functions correctly.

  • Reinforcement Composites

Reinforcement composites are a type of material that is made up of two or more different substances. The most common type of reinforcement composite is fiberglass, which is made up of glass fibers and resin. Reinforcement composites are used in a wide variety of applications, including automotive parts, boats, airplanes, and sporting equipment. They are prized for their strength, durability, and resistance to weathering.

In recent years, reinforcement composites have also become popular in the construction industry as an alternative to traditional materials like wood or concrete. Thanks to their many advantages, it is likely that reinforcement composites will continue to be used in a variety of industries in the years to come.
