Construction of Odisha’s first geo-synthetic wall put on hold


Odisha Sun Times Bureau
Rajnagar, Jun 24:

The authorities have decided to put the construction of geo-synthetic wall near Pentha under Rajnagar block in Odisha’s Kendrapara district in abeyance as a portion of it ruptured allegedly due to use of low quality materials and faulty design.

A meeting was held in the state capital on Tuesday under the chairmanship of Engineer-in-Chief of Water Resources Department Janaki Ballav Mohapatra where it decided to stall the construction of the geo-synthetic wall which is being erected to minimise sea erosion due to high tides from the Bay of Bengal. The meeting also decided to send the construction materials for tests to check their quality and alter the process of erecting the synthetic embankment.

Dr Sanyasiraj Solankar from IIT-Chennai, Saline Executive Engineer, Jugal Kishore Tripathy and seven chief engineers participated in the brainstorming session.

Notably, 40 geotubes having length of 20 meters and height of 7.4 meters each have been placed inside the sea so far. A total of 204 geotubes are proposed to be fitted in the geo-synthetic wall on a 505-meter stretch to stop the sea waves from eroding the coastline. However, only 40 geotubes have been fitted as of now.

The authorities are contemplating changing the process of erection of the wall as they are finding it difficult to place stone packings in 120 meter out of the 505-meter stretch geotube due to high tides.

Besides, it is alleged that inferior quality construction materials are being used in the erection of geo-synthetic wall after a geotube burst recently.

The authorities have decided to send the materials used for erection of geo-synthetic wall–polymer ropes, geo tube, geo cloth– to various laboratories at Delhi, Mumbai, Chennai and Pune for testing. The construction of the geo-synthetic wall will be stalled till the report comes, a source in the department said.

“Stainless steel sheet pipes will be used in piling where it will be placed 20 feet below the sea along the 120-meter stretch. Geo tubes will be fitted at the back of these steel piles. Besides, the process of construction of geo tubes with the filling of water and sand will be changed. The insertion of water and sand is exerting enormous pressure on the tubes as a result of which it is collapsing,” Saline Executive Engineer, Jugal Kishore Tripathy said.

This geo-synthetic tube wall project is the second geotube built in India after West Bengal, which was constructed in 2008 spread over an area of 1 KM.

The World Bank project funded under the Integrated Coastal Zone Management (ICZM) Programme has approved Rs 31.15 crore for the laying of geo-synthetic tubes. While 75 percent of the project cost will be borne by the World Bank, 15 and 10 percent will be spent by Central and state governments respectively.


  1. It appears that the geotextile tubes were constructed with a woven polyester fabric. It has been our experience that polyesters exposed to calcarious materials such as seashells and ulta violet light will rapaidly deteriorate. We had a very unfortunate experience at Tampa Bay Florida. Please send me an e-mail address and I will send you photos of the failed tubes.
