Geotextile Fabric for NTPC Project: Effective Stabilization & Erosion Control 

Ocean Non Wovens supplied 24,000 square metres of geotextile fabric for an NTPC project at Badarpur, Delhi, and supported its installation on site. The geotextile was used for ground stabilisation and erosion control on a large site with difficult ground and a high water table.

• Functions: Ground stabilisation, erosion control

Background

The NTPC project was a large-scale infrastructure development covering facilities and the surrounding area. Badarpur lies close to the Yamuna floodplain, and the complex ground conditions and high water table meant the site needed reliable ground stabilisation. Geotextile was chosen as the solution.

Challenges

The geotextile had to be cost-effective and efficient for a project of this size. It needed the strength and durability to survive harsh site conditions, and the flexibility to install quickly over a large area.

On wet, soft ground, the problems are predictable. Fill and aggregate placed directly on saturated soil sink into it and mix with it, so more material is needed and the finished surface settles. Exposed soil on slopes and open areas washes away in heavy rain. A geotextile fabric addresses both: laid on the soil before the fill, it keeps the two layers apart and spreads the load, while letting water drain through; on slopes, it holds the soil in place under a cover layer.

Solution

Ocean Non Wovens supplied geotextile fabric made for the demands of the NTPC project. It had high tensile strength and good puncture resistance, and was resistant to UV radiation and chemical degradation for long-term protection of the site. The fabric was also easy to install, which reduced installation time and cost.

Ocean Non Wovens worked with the project team so the geotextile was installed correctly and to specification, with on-site support and technical assistance throughout installation.

Result

The geotextile provided ground stabilisation and erosion control, preventing soil erosion and improving the stability of the site. It also helped reduce construction time and costs.

For ground stabilisation, separation or erosion control on soft or waterlogged sites, Ocean Non Wovens also supplies geogrids and geomembranes. See more projects on the case studies page.
