Geosynthetic materials are a broad class of materials, such as polymers, geotubes and geotextiles. Today, the role and importance of geosynthetic materials in civil engineering processes has increased because they can solve a wide range of problems with less budget.
One of the popular applications of geosynthetic materials is supporting weak foundations and acting as a barrier for conventional hazardous materials and waste. Geosynthetic materials have many other applications in civil engineering. Continue reading to learn all about them.
What are geosynthetic materials?
Applying geotechnical techniques to environmental problems falls under the category of geo-environmental engineering. Cleaning up contaminated sites, water resources engineering, wastewater treatment, handling and storing garbage, pollution control, rebuilding and protecting coastal areas, and flood control are some examples. In terms of application, geosynthetic materials play a greater role in interaction with soil, rock and numerous geotechnical materials. There are various geosynthetic materials to choose from; they can be synthetic or natural. Geotubes and geotextiles are some of the many examples of geosynthetic materials.
Application of geosynthetic materials on roads
Impermeable polymer sheets called geomembranes are used as solid and liquid waste containment barriers. Geogrids are rigid or flexible polymer sheets similar to grids. They have large gaps and are usually used to reinforce garbage dumps and unstable soil. Geonets are hard polymer sheets similar to nets with in-plane perforations. They are mainly used as drainage media in landfills. A bentonite layer incorporated between geotextiles and/or geomembranes and used as a liquid and solid waste containment barrier is called a geosynthetic clay liner. Geotubes are polymer tubes with solid or perforated walls for discharging a range of liquids. The following geosynthetic material types can be combined to create geocomposites, through which hybrid systems can be utilized to solve problems with soil, rock, garbage and liquids. Lightweight geofoam blocks can be used to fill gaps in specific construction projects.
Application of geosynthetic materials in drainage systems
In addition to replacing traditional granular materials, geosynthetic materials can also be used as drainage pipes and filters in civil and environmental activities. Geosynthetic materials are more convenient to use on site and are usually more affordable when granular materials are unavailable, scarce, or their use is restricted by environmental regulations. Traditional graded granular materials are used for filtration and drainage in many civil engineering projects. There are many different sizes and shapes of aggregate drainage pipes. A common type of drainage pipe with aggregate filling is the French drain, which is a trench filled with free-draining aggregate. The drainage requirements of traditional graded filter designs are difficult to meet. Using geosynthetic drainage systems with modern geotubes can quickly and economically create conditions. It has a drainage pipe and a filter. Along the plane of the geosynthetic material, water can flow without restriction. In addition, geosynthetic materials hold soil particles in place while allowing water to pass through their plane. This is one of the effective uses of geosynthetic materials.
Application of geosynthetic materials in slope stabilization
Geotextiles have been successfully used on multiple occasions to maintain steep slopes in regenerated soil and weathered rock. As tensile reinforcement and filters, geotextiles are used to stabilize slopes or embankments. Geotextiles are usually layered horizontally within the slope. It is parallel to the slope and passes through areas where soil may slide. Geotextiles will reduce the pore water pressure of the slope during the rainy season, improving shear strength. In addition, as a filter, geotextile can prevent soil migration within the slope, also known as internal erosion. Soil along possible sliding areas or planes is reinforced with geotextile. All of this increases the stability of the slope. This is one of the effective uses of geosynthetic materials. Many variables affect the selection of geotextiles in geotechnical engineering. One is the use of granular materials to build geotechnical structures; erosion, settlement and earthquakes can affect the continuity of granular soil layers, but geotextile layers do not. A two-dimensional flexible material called geotextile is also very suitable for geotechnical structures subjected to various movements. Geotextiles can also be used on the surface of large geotechnical buildings as liners, protective layers or layer interfaces. For various reasons, contractors, designers and owners choose to use geotextiles in geotechnical engineering. In summary, many problems faced in civil engineering can be solved by geosynthetic materials. This substance prevents erosion, shields or redirects water, and stabilizes soil and buildings. It can be made from a variety of substances, including rubber, plastic and fiber. Because geosynthetic materials reduce environmental consequences and create more livable environments for people, it is an important part of sustainable construction.
