Production Processes for Geosynthetics

Front

What are the main types of geosynthetics?

Back

Geotextiles, Geogrids, Geomembranes, Geocomposites, Geonets, Geofibres, Geostrap, Geomat, Geomesh, Geocells, Geotubes, Geobags, Geopipes, Geofoams.

Front

What are the raw materials used for geosynthetics?

Back

Synthetic fibres (e.g., Polypropylene, Polyester, Fibre Glass, Aramid) and Natural fibres (e.g., Jute, Coir, Sisal, Hemp).

Front

What is the significance of Jute in geosynthetics?

Back

Jute has better mechanical properties in dry state than conventional polyester/polypropylene fibres, is hygroscopic, eco-friendly, and has good adhesion with asphalt.

Front

What is the process of extrusion in the production of geosynthetics?

Back

Extrusion involves converting solid polymeric pellets into filaments, tapes, sheets, or films using a screw extruder.

Front

What is blown film production?

Back

A process where molten polymer is fed into a die, inflated to form a bubble, and cooled to produce tubular extrudate.

Front

What is calendering in the context of geosynthetics?

Back

Calendering is a process that involves rolling doughy plastic between hot steel rollers to produce sheets, commonly used for geomembranes.

Front

What are fibrillated slit film tapes?

Back

Tapes produced by splitting polymeric film or sheet into narrower strips, which are then drawn and reeled for weaving.

Front

What are the types of woven geotextiles?

Back

Plain, Twill, Leno, and Triaxial weaves.

Front

What is the difference between uniaxial and biaxial geogrids?

Back

Uniaxial geogrids are drawn in one direction to form rectangular apertures, while biaxial geogrids are drawn in both directions to form square apertures.

Front

What are geonets used for?

Back

Geonets are primarily used as fluid conducting cores, especially in drainage applications.
