Functions

Separation
In Separation, the geotextiles prevent intermixing
of adjacent dissimilar soils or fill.

Drainage
In Drainage, geotextiles are used to provide an
avenue for the flow of water through the plane
of the geotextiles. Geotextile acts as a passage,
trapping soil particles and preventing clogging
while letting fluids and gases move freely along its
plane.

Filtration
In Filtration, the geotextiles allow for adequate
liquid flow with limited soil loss across the plane of the geotextile.

Protection
Geotextiles extend the life of the lining
system/Geomembrane by protecting it from
punctures and excessive deformation.

Moisture Barrier
Though relatively impermeable, Geotextiles fabrics
have a high load-bearing capacity, and a rougher.

Reinforcement
Geotextiles provide tensile strength to the soil or
other materials which helps to resist deformation
and maintain the structural integrity of the
material.

Road Stabilization : Road stabilization is one of the most common applications of NASK geotextiles. In this application, the fabric is used to improve the structural integrity of roads and prevent damage caused by traffic, weather, and other factors. NASK Geotextile performs this function when impregnated with asphalt or other polymeric mixes rendering it relatively impermeable to both cross-plane and in-plane flow.

Sideways : Non-woven geotextile offers excellent separation, reinforcement, and drainage properties, and has several benefits such as improved durability, stability, and performance, preventing soil erosion reducing maintenance costs, and extending the lifespan of the road. Geotextile can also improve the drainage capacity of the road, reduce soil settlement, and prevent the formation of potholes and cracks. All these properties make it ideal for road construction.

Paved Blocks : The classic application of a geotextile as a liquid barrier is paved road rehabilitation, Here the non-woven geotextile is placed on the existing pavement surface following the application of an asphalt. The geotextile absorbs asphalt to become a waterproofing membrane minimizing the vertical flow of water into the pavement structure. Geotextiles are used in paved roads and runways to provide reinforcement, separation, drainage, and filtration. It helps to control the development of common pavement distress features such as rutting and cracking which can compromise the safety and durability of the runway and helps to distribute loads evenly.

Runways : This is accomplished by structural reinforcement of the base aggregate layer, controlling infiltration into moisture-susceptible layers, and preventing contamination of structural layers by the migration of fines from underlying soils. These functions help preserve and, in some cases, enhance the structural integrity of the constructed pavement layers.

Railroad Stabilization : This is accomplished by structural reinforcement of the base aggregate layer, controlling infiltration into moisture-susceptible layers, and preventing contamination of structural layers by the migration of fines from underlying soils. These functions help preserve and, in some cases, enhance the structural integrity of the constructed pavement layers.

Drainage System : In drainage, the geotextiles act as a horizontal drainage channel for liquids or gases. For underdrains constructed along pavements, the gravel-filled trenches lined with geotextiles allow water to drain into the trenches and separate or restrict soil materials, thereby preventing blockages that can reduce the flow of water and increase the risk of flooding and preventing damage to road structure and prolonging life of structure. For drainage, non-woven geotextiles are the preferred choice due to the small pore size and high flow capacity.

Roofing : Non-woven geotextile fabrics are also used in roofing applications to provide a protective layer between the roofing membrane and the underlying substrate to ensure the proper functioning and longevity of the roofing system.

Waste Containment : Non-woven geotextile fabrics are widely used in waste containment applications due to their superior strength, durability, and permeability properties. Waste containment refers to the process of safely storing or disposing of hazardous or non-hazardous waste materials to prevent environmental contamination and harm to human health.
