Problem Description

Solution Proposed

Considering the vital importance of the project for an effective growth of the city and protection of the environment, Consultants approved the use of Nonwoven Geotextile in the Himmatnagar landfill site. TechFab (India) Industries Ltd met all the tender specifications required for the Nonwoven Geotextile to be used in the landfill site. 

TechFab (India) Industries Ltd thereby successfully supplied TechGeo Nonwoven Geotextile with mass per unit area of minimum 500 Gsm. TechGeo (Nonwoven Geotextile) supplied was made of Polypropylene staple fibre, needle punched and UV stabilized as per the tender specifications. Third party testing of TechGeo was carried out at Central Institute of Plastics Engineering & Technology (CIPET) and was found satisfactory.

Execution On Site

TechGeo polypropylene staple fibre Nonwoven Geotextile serves multifold applications at a Landfill site, which are as follows:

TechGeo acts as a “Cushion” (protection layer) to protect to the Geomembrane liner which is used as barrier against all forms of liquids, gases etc. TechGeo protects the Geomembrane liner against any puncture from any external means.

TechGeo acts as a “Separator” (separation layer) at the landfill sites by preventing the mixing of two dissimilar materials above and below the TechGeo layer. Thereby the TechGeo prevents any clogging of drainage system.

TechGeo acts as a “Filter” (filtration layer) at the landfill site by preventing any soil particles from entering into the drainage system.

TechGeo acts as a “Drain” (drainage media) at the landfill site by allowing in plane drainage of water through it. The drainage of Leachate is carried out by other drainage mediums like drain board etc.
