ROLE OF GEOBAGS AND GABIONS IN FLOOD PROTECTION
Floods, a natural calamity, can happen in just a moment. A once picturesque landscape with a meandering stream or calm river can, in minutes, transform into a raging deluge, powerful enough to cause

The world we live in today faces many serious threats, of which climate change and its detrimental impacts are things we cannot ignore. A rise in sea level is a known consequence of climate change. There can be massive environmental and socio-economic impacts due to flooding. Safeguarding people, property, and other valuable

Depending on sitespecific situations, geosynthetics offer cost-effective and longerlasting solutions to various construction and engineering purposes. The Geobags and Gabions, in particular, come to the rescue with their

Geobags Manufacturers in India, made Geobags of either heavyduty woven or nonwoven geotextiles like polypropylene, polyester, or polyethylene, the Geobags placed within steel Gabions or PP rope Gabions and placed at regular intervals impart stability to scour protection.

The Gabion baskets or wire mesh containers stacked together with locally filled material provide a stable structure for flood-prone waterways. The highly galvanized metal mesh is corrosion resistant providing a longer design life. Gabion flood barriers have welded wire mesh panels joined and reinforced with spiral joints giving them higher strength to withstand the powerful impact of water currents and other debris.
