Product Expertise: At the heart of geohazard mitigation activity

TechFab India’s Highest Quality Products for Rockfall Protection & GeoHazard Mitigation

TechFab India was founded in 2003 with the objective of providing world- class geosynthetic products and services to cater to the needs of infrastructure and construction sectors. TechFab India is now India’s leading manufacturer of geosynthetics in terms of the variety and high quality of our products and exceptional manufacturing capacity.

The company manufactures a very wide range of products at its three state-of-the art facilities located in Silvassa and Daman including TechGrid and TechGrid PP geogrids, TechStrap geostrips, TechGeo nonwoven geotextiles, TFI 3000 woven geotextiles, TechPave paving geotextiles, TGC reinforced nonwoven composites, TechTube geotextile bags and tubes, TechCell geocells, TechDrain PVDs and drainage composites and TechFab metal gabions. All these products have the prestigious GreenPro certification guaranteeing that its products are environmental friendly throughout its life cycle.

Having successfully met the challenge of ensuring adequate supplies of world-class indigenously manufactured geosynthetics for the growing needs of the rapidly expanding infrastructure sector, TechFab is expanding its business to serve the needs of geohazard mitigation. The effects of climate change and associated extreme rainfall events are triggering geohazards on an unprecedented scale, threatening lives, livelihoods, lifelines and property. The company has focused on the development of a new range of products to facilitate engineered structural measures for geohazard mitigation.

Landslides, rock falls, avalanches and other slope failures triggered by extreme rainfall events and developmental activities are increasingly becoming a major hazard in mountainous and hilly areas. Measures for controlling slope failures and protecting the lives of the people residing in these areas and the large number of tourists and pilgrims travelling to these locations are to be accorded the highest priority. Recognizing this critical need, Techfab India has established a state-of-the-art manufacturing facility at Haridwar, Uttarakhand to produce a new line of engineered high performance products made from high quality steel, which have extensive applications in slope stabilization and rockfall protection.

TechFab India’s range of specialty products specifically engineered for the mitigation of geohazards associated with slope failures includes the following product lines:

TechRhombus High Tensile Rope Net System

TechRhombus is a very strong, tough and flexible steel rope net system comprising high tensile steel wire ropes (1960 N/mm2) and steel wire knot (SWK) or high resistance clip (HRC) jointing systems which can be used for both active and passive rock fall protection. TechRhombus with Galfan/Galvanized coating has exceptional corrosion resistance.

In the simple drapery system for rock fall protection, TechRhombus is used as the primary mesh and a layer of double twisted hexagonal steel wire mesh is used as the secondary mesh. Both meshes are secured with top layer of anchors/rock bolts and top support rope secured with wire rope anchors.

TechSlope Mesh Flexible Slope Stabilization System

TechSlope Mesh is a very strong and flexible net made from high tensile steel wires which is used as a flexible facing system for stabilizing rock and soil slopes in combination with rock bolts / anchors / soil nails. The mesh is connected to anchoring elements using steel bearing plates or using a grid beam method. The product with Galfan coating has exceptional corrosion resistance. Adjacent TechSlope Mesh panels are connected using special connection clips. TechSlope Mesh facing systems have several advantages over conventional rigid facings like shotcrete.

Major advantages of TechSlope Mesh include:

  • High tensile strength
  • Light weight
  • Exceptional corrosion resistance with Galfan coating
  • Economical
  • Green solution

TechAnchor Self Drilling Anchors

TechAnchors are high performance self-drilling anchors with high tensile strength, excellent bond with soil and rock and exceptional durability. TechAnchors are available in various sizes and with protective coatings like zinc, epoxy etc. The anchors are supplied with all required accessories like drill bits, couplers, bearing plate and hex nuts. Several types of drill bits like cross, clay, jetting, segment etc. are available to suit different site conditions 

TechAnchor system is fully compliant to EN 14490. TechAnchors are designed to drill without casing in loose soils as well as rock. These have extensive applications in slope stabilization, retaining structures, foundations of structures, tunnelling and mining. The system can be used for both temporary and permanent applications.

With TechAnchors, there is no need for cased boreholes and there is increased productivity since drilling, insertion and grouting is done in a single operation.
