Non woven geotextiles are widely used in civil engineering projects as they provide economical and effective solutions for a variety of applications. Geotextile fabric is made from synthetic materials that are designed to provide mechanical and hydraulic properties to the soil. Non woven geotextiles are made from polypropylene fibers that are needle-punched together; it is a porous fabric with high permeability. In this article, we will discuss the applications and uses of non woven geotextiles in civil engineering projects.
Soil Stabilization
Non woven geotextiles are used to improve the stability of the soil by preventing soil erosion and enhancing its load-bearing capacity. The geotextile layer is placed between the subgrade and the aggregate base, allowing for effective drainage while preventing the base material from mixing with the subgrade. So, it acts as a separation layer and supports the prevention of soil pumping when heavy traffic or rainfall results in forcing up the water through the base material is called soil pumping.
Waste Containment
Non woven geotextiles are commonly used in waste containment projects, where they are used to prevent the migration of contaminants into the surrounding soil and water sources. They are placed between the waste material and the soil and prevent the contamination of the soil and groundwater. Non woven geotextiles are also used in landfill liners to prevent leachate from escaping into the surrounding environment.
Road Construction
Non woven geotextiles are more often used in road construction to improve the strength and durability of the road surface. They are placed between the subgrade and the base layer of the road, preventing the migration of soil particles and providing reinforcement. The geotextile layer also helps to prevent the formation of cracks due to traffic loads and temperature changes.
Erosion Control
Non woven geotextiles perform fantastically in areas with high water flow or steep terrain for the prevention of soil erosion. They are used to stabilize the soil by providing a layer of protection that prevents soil particles from being washed away. Non-woven geotextiles are also used in shorelines and riverbanks for their stabilization, where they provide stability to the banks by stopping soil erosion.
Landscaping
Non woven geotextiles are often used in landscaping projects to control soil erosion and promote the healthy growth of plants. They are commonly used in the prevention of soil erosion on steep slopes and facilitate the planting of vegetation that helps to stabilize the soil. Another beneficial application of Non woven geotextiles is their use in gardens and flower beds to prevent weed growth and provide a stable foundation for the soil.
Retaining Walls
Non woven geotextile fabric is an essential component of retaining walls, as it provides stability and reinforcement to the structure. It is used to prevent soil erosion behind the wall and provide a stable foundation for the wall. The geotextile layer also helps to distribute the load of the wall evenly, preventing it from cracking or collapsing.
Drainage Systems
Non woven geotextiles are an essential component of drainage systems in civil engineering projects. They are used to create a drainage layer that promotes the efficient movement of water away from the structure or site. This plays a pivotal role in the prevention of water damage and soil erosion by directing the water to a selected location. Non woven geotextiles are also used to line drainage ditches and channels; they allow efficient water flow by avoiding the loss of soil particles.
