“In 2024, a coastal highway in Southeast Asia faced severe erosion during the monsoon season. Traditional stone revetments were costly and slow to deploy. TYNOD Geobags provided a fast, durable, and eco-friendly solution that stabilized the shoreline within weeks.”
Geobag from TYNOD
Geobag, also known as geotextile bag or sandbag, is a versatile and cost-effective geosynthetic product widely used in hydraulic engineering, environmental protection, and soil stabilization projects. It is made from high-strength, UV-resistant, and permeable nonwoven or woven geotextiles. Geobags are filled with local sand, soil, or other materials on-site, forming durable structural units for erosion control, slope protection, and shoreline stabilization.
With over 15 years of experience in the geosynthetics industry, TYNOD supplies a complete range of geobag solutions designed to meet the diverse needs of global infrastructure and environmental projects.
Types of Geobag
TYNOD offers various types of geobags to suit different construction and environmental applications:
Nonwoven Geobag
Made from high-quality nonwoven geotextiles, these bags provide excellent permeability and filtration performance. They are widely used for riverbank protection, slope stabilization, and landscaping works. Nonwoven geobags allow water to flow through while retaining soil particles, reducing erosion effectively.Woven Geobag
Woven geobags are manufactured using high-strength woven polypropylene or polyester fabrics. They feature low elongation and high tensile strength, making them suitable for applications that require structural stability and resistance to mechanical stress, such as coastal protection and embankment reinforcement.Customized Geobag (UV-Resistant or Coated Types)
For projects in harsh environmental conditions, TYNOD provides UV-resistant or specially coated geobags to enhance durability against sunlight, chemical exposure, and abrasion. These are ideal for long-term installations such as shorelines, seawalls, and river training works.Plantable Geobag
These eco-friendly geobags are designed to support vegetation growth, combining soil stabilization with ecological landscaping. They are often used in riverbank rehabilitation, green slopes, and eco-engineering projects.

Applications of Geobag
Geobags are used in a wide range of infrastructure, hydraulic, and environmental applications due to their adaptability, strength, and cost-effectiveness.
Riverbank and Shoreline Protection
Geobags are installed along riverbanks, canals, and shorelines to prevent erosion caused by water flow and wave action. When stacked together, they form stable revetments that absorb hydraulic energy and protect the embankment.
Slope and Embankment Stabilization
On slopes and embankments, geobags provide structural reinforcement and prevent soil erosion, especially in areas exposed to rainfall or flowing water. Plantable geobags can be used to combine engineering stability with natural vegetation.
Coastal Protection
In coastal engineering, geobags act as flexible armor units for seawalls, groynes, and breakwaters. Their ability to deform under hydraulic loads helps them adapt to settlement without structural failure.
River Training and Channel Works
Geobags are used in river training structures to guide water flow and protect the riverbanks from scouring. They are often used as an alternative to traditional stone pitching or concrete blocks.
Temporary Flood Control Structures
Due to their ease of handling and rapid installation, geobags are ideal for emergency flood control measures, such as temporary levees and dikes.
Environmental Rehabilitation Projects
Geobags support eco-engineering methods, helping to restore riverbanks, wetlands, and shorelines with vegetation while maintaining structural stability.

FAQ
What are geobags used for in coastal protection?
Geobags are widely used for coastal protection and shoreline stabilization. Filled with sand or soil, they act as flexible and permeable structures that help prevent erosion, dissipate wave energy, and reinforce embankments. Compared to rigid materials, geobags for coastal protection are easy to install, environmentally friendly, and cost-effective for both temporary and permanent solutions.
How long do geobags last in marine environments?
The lifespan of geobags in marine environments depends on the material type, UV resistance, and installation quality. Typically, high-quality polypropylene or polyester geobags can last between 5 to 20 years in harsh coastal conditions. When properly installed and covered with vegetation or additional protective layers, geobags in marine environments offer long-term stability and performance.
Can geobags replace traditional stone or concrete?
Yes, geobags can replace traditional stone or concrete in many coastal and riverbank protection projects. They offer several advantages: lighter weight, easier transportation, faster installation, and lower overall cost. Geobags also adapt better to ground settlement and irregular surfaces, providing a flexible alternative to conventional hard structures like riprap or concrete blocks.
How to choose between woven and nonwoven geobags?
Choosing between woven and nonwoven geobags depends on your project’s hydraulic conditions and performance requirements.
Woven geobags offer higher tensile strength and are suitable for high-energy environments like riverbanks or coastal seawalls.
Nonwoven geobags provide better filtration and permeability, making them ideal for drainage and erosion control applications.
Consider factors such as flow velocity, soil type, UV exposure, and expected lifespan to select the most appropriate type.
