Erosion Control

Erosion is caused by the migration of fine soil of sea or river banks due to strong currents. This ultimately poses a great danger to installations located on the banks. This is one of the most common problems with granular soil.

After dressing the eroded banks, Supertex geo-textile – manufactured from a synthetic fibre resistant to alkaline and acidic attack – is laid and anchored. A boulder rip-rap is formed on the geo-textile layer as a protective layer.

Supertex geo-textile functions as a filter and permits water to pass through without allowing the migration of fine soil. Since Supertex is resistant to deterioration caused by UV exposure and has good tensile and hydraulic properties, various geo-technical designers have come to prefer Supertex to encounter river and sea erosion in recent times.

Reinforced Earth Walls

For the construction of reinforced earth walls, modern designers prefer vertical constructions, with side concrete facia to add aesthetic value. Apart from visual appeal, this design helps avoid litigation problems of land acquisition mainly in urban areas, where flyovers with service roads are designed to ease traffic congestions.

Supertex geo-textile is widely used as a back filter behind the concrete facia. Several designers deem it a handy filter media to retail soil particles of backfill material in place, even as it allows the release of accumulated hydraulic pressure.

Filtration

Supertex geo-textile has become a handy solution for draining out accumulated water from areas like coal yards by using the French/Trench drain principle. Many construction engineers often encounter the problem of water-logging during the monsoon at unpaved but critical storage or working areas.

Perforated pipes wrapped with Supertex geo-textile allow water to drain out, retaining soil particles in place.

Separation

One of the major applications of Supertex geo-textile is as a separator between the subsoil and the aggregate layer of the roads. This protects the aggregate layers from sinking into the subsoil. At the same time, it also allows excess pore water to pass through.

As a result, the life of roads under dynamic loading conditions improves considerably. Depending on the condition of the subsoil, designers may use single or multiple separators at intervals to improve road quality. This is used for both paved and unpaved roads.

Paving

Asphalt-impregnated Supertex geo-textile functions as a moisture barrier and a stress-relieving interlayer. It provides several benefits to pavements, particularly by retarding reflection cracks. Thus, it reduces road maintenance coast, increases road life and improves pavement serviceability.

Protection

For the disposal of solid waste and hazardous landfill, structures are designed with an impervious geo-membrane layer along with geo-textile. Supertex geo-textile protects the membrane from succumbing to construction stress, due to its high tear strength and puncture resistance.

Supertex geo-textile is manufactured from synthetic polymers that have high chemical resistance to both acidic and alkaline pH as well as extremely high UV resistance. Apart from protecting the membrane, Supertex acts as a drainage gallery, ensuring that ground water contamination doesn’t take place.

Supertex is also used in the construction of ash-ponds, along with an impervious geo-membrane layer, which keeps the membrane from puncturing. In the absence of this structure, there is a danger of ground water contamination. This is because thermal power stations usually dispose fly ashes in ash-ponds.
