Geotextile tubes, also known as geotubes, are gradually replacing traditional anti-erosion and sand control structures such as dams and seawalls in coastal areas. Behind their rapid development lie remarkable technical advantages. In terms of material properties, geotextile tubes are usually made of high-strength and corrosion-resistant synthetic fiber materials. These materials have good tensile strength and UV resistance, enabling them to work stably for a long time in harsh natural environments, with a service life of up to several decades. In terms of construction convenience, geotextile tubes are easy to install and do not require large and complex construction equipment. They can be filled on-site according to actual engineering requirements, and their size and shape can be flexibly adjusted, which greatly reduces the construction difficulty and cost. In addition, geotextile tubes have outstanding ecological friendliness. They allow water and air to pass through freely, effectively intercepting sediment while providing habitats for aquatic organisms, which helps maintain ecological balance.

Based on the above technical advantages, geotextile tubes play a crucial role in coastal management and soil erosion control, effectively slowing down the rate of soil erosion in beach areas. At the same time, they are also used to purify waterways, ensuring the water safety of humans and fish. Geotextile tubes can be found in various water purification processes, such as sludge treatment, dewatering, and wastewater treatment. In addition, the increase in dredging operations has further promoted the development of the geotextile tube market.

In January 2024, the geotextile tube project in Kerala, India, received funding of over $18 million from the state government. In October 2022, the Indian village of Pedamainavanilanka also witnessed a geotextile tube project funded by the Indian government. The advancement of these projects not only reflects the government's emphasis on environmental protection and coastal protection but also injects new vitality into the development of the geotextile tube market. With continuous technological progress and the continuous expansion of application areas, geotextile tubes are expected to play an even greater role in the future, contributing to global environmental protection and infrastructure construction.
