Geotextiles are categorized into different weight classes based on their mass per unit area. These weight classes range from lightweight to heavyweight.
Lightweight geotextiles, usually less than 200 grams per square meter (gsm), are commonly used in erosion control applications, such as slope stabilization and vegetation support. They provide filtration and separation functions while allowing water to pass through.
Medium-weight geotextiles, typically ranging from 200 to 400 gsm, are often employed in applications like road stabilization, embankment reinforcement, and subgrade separation. They offer a balance between strength and permeability, ensuring proper drainage and preventing soil movement.
Heavyweight geotextiles, exceeding 400 gsm, are primarily used in applications requiring high strength and durability. These include shoreline protection, coastal engineering, and land reclamation projects. They provide robust reinforcement and act as a barrier against erosion and wave action.
The choice of geotextile weight class depends on the specific engineering requirements of the project, such as soil conditions, anticipated loads, and desired drainage characteristics.
Geotextile weight classes range from light to heavy, with each class having specific applications. Lightweight geotextiles are typically used for erosion control, landscape projects, and separation of materials. Medium weight geotextiles are commonly used for filtration, drainage, and reinforcement purposes. Heavyweight geotextiles are suitable for projects that require strong stabilization, such as road construction, embankment reinforcement, and landfill capping.
Geotextile weight classes range from lightweight to heavyweight, typically categorized as classes 1 through 5. Class 1 geotextiles are lightweight and used for erosion control, filtration, and separation in landscaping and gardening projects. Class 2 and 3 geotextiles are medium-weight and commonly used for road construction, pavement reinforcement, and drainage applications. Class 4 geotextiles are heavy-duty and suitable for shoreline protection, slope stabilization, and landfill lining. Lastly, Class 5 geotextiles are the heaviest and used in geotechnical engineering for applications such as soil stabilization, embankment reinforcement, and railway construction.
