Mumbai, Maharashtra, India | Municipal Corporation of Greater Mumbai
Road 14, Shivaji Nagar is location in Govandi near Deonar Dumping Ground, one of the largest dumping grounds in Mumbai, the road is adjacent to the dumping ground and due to the leachate of landfills, water accumulation during monsoon the nearby soil become marshy and the ground water table also rise which make the subgrade foundation of the pavement weak, so roads needs to be maintain regularly due to such problems. Looking at the advance solution available using Geosynthetics, MCGM (Municipal Corporation of Greater Mumbai) decided to construct pavement doing proper soil stabilization using Geosynthetics.
Due to above mentioned problem of soft marshy soil and high ground water table, the only prepared subgrade was not enough to act as foundation to pavement as it was not providing desired stability and resulting it in failure of existing road. Conventional solution for such problem is the Soil stabilization by adding suitable stabilizers to enhance the existing soil properties but it is uneconomical as well difficult to maintain the quality of the stabilized soil is such large quantum. After comparing cost and long term benefits of geosynthetics MCGM authority decided to use geosynthetics for subgrade stabilization.
Consultant has suggested using Techgrid Biaxial Geogrid and TFI Woven Geotextile at GSB level for this problem. The pavement section for given CBR and traffic data is designed as per IRC 37 2012. To enhance the performance of pavement a layer of Biaxial Geogrid as reinforcement and woven geotextile as separator layer are provided at GSB level.
The solution suggested here is less time consuming, easy to install, economical and provide durable solution with good life.
Project was executed in 2019. Client was happy with timely supply and quality of material. Roads are functioning as expected with low maintenance costs.
The road lies next to the Deonar Dumping Ground. Leachate from landfills, monsoon water accumulation, and a high groundwater table made the soil marshy, weakening the pavement subgrade and causing repeated failures.
Traditional soil stabilization using chemical stabilizers was uneconomical and difficult to maintain at such a large scale. The weak subgrade continued to compromise pavement durability.
Consultants recommended TechGrid PET Biaxial Geogrid and TechGeo PET Woven Geotextile at the granular sub‑base (GSB) level. This geosynthetic reinforcement stabilized the weak soil, improved load distribution, and provided a durable foundation.
Yes, the pavement section was designed as per IRC 37:2012, ensuring compliance with Indian Roads Congress guidelines for traffic and soil conditions.
Executed in 2019, the project delivered a stable, durable road with significantly lower maintenance costs. The Municipal Corporation of Greater Mumbai was satisfied with the timely supply, quality, and performance of the solution.
By applying advanced geosynthetics to solve urban infrastructure challenges, TechFab India demonstrated its ability to deliver sustainable, cost‑effective, and high‑performance road solutions in demanding environments.
