GEOSYNTHETIC APPLICATIONS IN PAVEMENTS
TECHFAB INDIA INDUSTRIES LIMITED, is an ISO 9001-2008 certified organization, keen in introducing the most efficient and cost-effective solutions for the all the engineering geosynthetic problems. Techfab manufacture World Class Geosynthetic products at its state of art manufacturing units in Silvassa and Daman (UT) India, which exceed expectation and provide exceptional service around the globe since 2003. Towards this we have established offices in most of the metro cities in India and are headquartered in Mumbai
TechFab India's product portfolio is useful in a multitude of applications like Slope Protection and stabilization, Reinforced soil wall, Railway track bed stabilization, Pavement strengthening, Coastal protection , Landfill, Landscaping, Ports, and most of the Environmental engineering problems.
In India, infrastructure developments are at their highest peak at present since the country's new government came in power, says Mr. Manish Barot, Head – Technical Sales & Business Development, TechFab India. . As such, major projects are underway for highways, coastal highways, railways, port development, coastal and river training works, and solid waste management he added.
“During such developments, so many problems are also associated with the infrastructure constructions such as alignment of roads and railways through problematic ground conditions, constructions of roads railways nearby coastal area for better connectivity with the ports where ground conditions are poor and also the scarcity of natural resources (stone, sands, gravel, etc.), and high ground water table & drainage issues,” Barot says.
In his opinion, advanced applications need to be adopted by government authorities. “As a result, the last couple of years have seen various geosynthetic applications grow slowly, but will continue to grow day by day. The prominent manufacturing industries—like us—are putting in a lot of effort to educate the client, consultants and contractors, giving them examples and showing case studies from developed countries like the U.S., U.K., and in Europe where these types of applications are widely used and still in practice. We believe that this will definitely give good results in the future for growth of the geosynthetic industry in India.”
And Techfab India is geared up and ready to provide the best geosynthetic products to the industries to deal with different geotechnical solutions where conventional solutions has their limitations. In last couple of years, Techfab India has added additional manufacturing facilities for following products which are the present need of industries.
TechGrid PP Biaxial Geogrid
TechGrid PP Biaxial is an integrally formed biaxial geogrid that has been manufactured using punched and drawn procedure using quality polypropylene. The polymer has been stabilized using over 2.0% carbon black. The main applications of the TechGrid are Base and sub base stabilization in pavement , Trackbed stabilization in Railway and soil reinforcements.
The main mechanism of the PP Biaxil Tech Grid Geogrid is by giving the lateral confinement by interlocking of the aggregates , which
• Limits horizontal movements of aggregate
• Increases stiffness, at equal deformations it is possible to apply a higher load.
• Decrease in vertical stresses applied to subgrade and an increase of compressive horizontal stresses thus decreasing the possibility of crack formation

Lateral confinement of aggregates by PP Biaxial Geogrid for pavement and Track bed stabilization in Railway.
TechDrain Drainage Composite
A drainage composite TechDrain is used for drainage in pavement and retaining structures. It is a combination of a geonet and nonwoven geotextile. The geotextile used here is either needlepunched or a thermally bonded nonwoven geotextile, and the net/core used in between the two geotextiles or the one side geotextile is made up of high density polyethylene (HDPE).
When a geotextile is used on one or both sides of a geonet, the separation and filtration functions are always satisfied, but the drainage function is vastly improved in comparison to only geotextiles

TechCell Geocell
TechCell is a light weight yet strong, 3D honeycomb like cellular confinement system, which offer unique, eco-friendly solution for various civil engineering challenges. Engineered for diversity, TechCell can be utilised in various sectors such as roads, railways, ports and others.
Techcell Geocell are widely used in construction for erosion control, soil stabilization on flat ground and steep slopes, channel protection, and structural reinforcement for load support and earth retention.
Typical cellular confinement systems expanded on-site to form a honeycomb-like structure and filled with sand, soil, rock, gravel or concrete or available local soil or recycled materials.
The strength and stiffness of pavement layers determines the performance of highway pavements while aggregate use impacts the cost of duration of installation; therefore alternatives are needed to improve pavement quality using new materials with less aggregate usage or locally available materials or recycled materials, Geocells are one of the suitable geosynthetic reinforcement of granular soils to support static and moving wheel loads on roadways, railways and similar applications. But stiffness of the geocells was identified as a key influencing factor for geocell reinforcement, and hence the rigidity of the entire pavement structure.
